Best RV Propane Tank Gauge Reviews

1. dozyant pol propane tank adapter.

This propane cylinder gauge is one of my favorites, mainly because it is made of 100% solid brass. Having this construction material means that this gauge is pretty tough and highly resistant to denting and cracks. It is also pretty resistant to corrosion. With that, you can be sure that this gauge will last for many camping seasons.

Another reason why I like this propane grill gauge is that it does not require the use of any special tools to install. In fact, it does not require any kind of tool at all. There is a built-in hand grip for easy installation. It only took me less than a minute to get this product installed. It just needs to be hand-tight. Do not over-tighten or you might ruin the threads.

I am glad that I no longer need to disconnect the tank to check if there is still propane inside it. The gauge will let you monitor in real-time how much propane there is in your tanks. With that, you will surely find it easier to know when you need to get the tank refilled. It can save you from the hassle of driving out of the campsite and getting a spare propane tank.

Probably the best feature of this gauge is that if your RV uses the outdated propane connection, it will convert it so that it can use the modern connection types. I like this feature because it allowed me to use propane tanks with regulator valves, which gives an added layer of safety.

• Easy to install as it does not require the use of any tools
• Can monitor tank contents in real-time
• Can help figure out if tanks are leaking
• Converts outdated connection to modern propane connection type
• Needle and face of the gauge glow in the dark
• Needs to be removed to close the propane access doo

2. SHINESTAR Gas Pressure Gauge

With the help of this propane tank gauge level indicator, you can quickly tell if the contents are running low. The gauge is color-coded to help you understand the status of the propane tank quickly. Green means the tank still has a lot of propane, yellow means it is starting to run low, and red means it is almost empty, and you need to refill it.

I think the best feature of this propane tank level gauge is the presence of different dials – with each one corresponding to a temperature change. For instance, if you are taking a reading on a particularly hot day, the dial gauge that you should follow is the outermost one where the measurement completely encircles the gauge face.

This gauge is also easy to install, thanks to the hard plastic grip. You can connect the business end of the gauge on your RV’s gas inlet valve using just your hands and without the need for specialized tools. It prevents over-tightening of the fittings that will eventually lead to leaks.

Just like with the first propane gauge, this gas pressure gauge from SHINESTAR will be able to tell you if the propane tank has leaks. This handy safety feature just might save you and your family’s lives soon because you can detect dangerous leaks before you even strike a match.

• Easy to connect without the need for any additional tools
• Works effectively as a leak detector
• Comes with a color-coded dial, which makes reading easier
• Features different meters for different temperature shift readings
• Made from 100% durable brass construction
• The plastic grip is a bit fragile.

3. Camco Propane Gauge

This RV propane tank gauge replacement will fit into the older propane inlet valves that are in RVs, boats, and propane gas grills. I use this on my ten-year-old RV so I can use modern tanks, and it is working great as a converter.

The gauge’s dial is labeled clearly. It only takes a short glance for me to find out if the propane gas level is getting low. I no longer have to lift the tank to check if there is still enough inside for my next trip. I find this helpful because my lower back is not the same as it used to be.

The dial has three measurements. The one that reaches until the end is for when the temperature outside is a bit hot. It is because propane tends to expand when heated. The shortest measurement is for when the temperature is a bit cold. It is because you can expect this gas to contract when cooled.

The median is for when the outside temperature is right in the middle of the two extremes. This propane tank gauge for RV provides additional protection against leaking lines as well as thermal protection against open flames. You can tell if your tank or gas line is leaking when the needle gradually drops even if you are not using any propane.

• Provides extra protection against flames
• Can help find leaks
• Has a clearly labeled dial
• Useful as a converter for using modern fittings
• Made of durable materials
• Not that accurate when the temperature is cool

4. DOZYANT Propane Tank Gauge

One thing that I liked the most about this product is how easy it is to install and detach when needed. You do not need to use any special tools. You just need your hand. It is not recommended that you use tools for it as the risk of over-tightening is real. Using a tool like a wrench will make it very easy to over-tighten.

Also, brass is a relatively soft metal, so it might ruin the threading. I am also glad that this gauge can fit all RVs, grills, and boats that have Type-1 connection. It also acts as a converter so that you can connect it to more modern fittings. This gauge can accurately work on propane tanks that can hold up to 40 pounds of fuel.

If you have a larger propane tank at home, then you can also use this gauge on it. Another neat benefit of this propane gauge is that you can use it on regular propane tank cylinders and propane regulators with a hose and propane adapter. The latter feature is great when you are using it on your grill and smoker at home.

The large dial is excellent because I can quickly tell how much propane is still in the tanks. I do not need to squint my eyes to take a reading. Also, the dial is color-coded, so it only takes a glance to get an idea of the amount of gas left in the tank.

• Has a large clear, color-coded dial
• The needle and dial face glow in the dark
• Easy to install, as you do not need any tools during the process
• Also works as a converter from old fashioned fittings to modern ones
• Can also be used with propane lines with regulators
• Sticks out too much, preventing the closing of the access door

5. AP Products 024-1000 LP Tank Check Dual Sensor

This product is a neat little system that allows you to monitor the amount of propane left in two tanks accurately. It comprises of two sensors that magnetically attach to the bottom of the tanks. It also has a propane tank monitor that will let you check how much propane is left in both tanks.

Aside from the RV propane tank level indicator that already came with the package, there is also a free app that the user can use to get even more detailed readings. Just download and install the app, Bluetooth-pair the magnetic propane tank gauge with your smartphone, and you are done.

I also love the fact that it is easy to install. You just need to install the rubber “feet” that came with the package on the bottoms of the tanks to provide enough clearance for the sensors. After that, just slap on the RV propane tank level sensors at the bottom of the tanks. You can screw the monitor onto any flat surface on your RV.

If you do not want to ruin the dash of your RV, you can just use ordinary mounting tape. The monitor is not that heavy anyway. This propane tank scale is great because it comes with an app that can accurately measure the amount of gas there is left in two separate propane tanks. It removes all the guesswork, making the margin for error is small.

Aside from giving you a rough estimate, you will also gain an idea of the exact amount of propane left in the tank. There is one issue that should not exist if the manufacturer would just supply the correct component. The problem is with the rubber spacer that prevents the tank from damaging the sensors.

• Easy to install, no drilling required
• Accurately monitors the contents of two different propane tanks
• Comes with a monitor that you can mount easily on the RV’s dash
• Can also be monitored using a smartphone via the free app provided
• Can get extremely detailed information via the smartphone app
• The included rubber “feet” are very fragile.

6. GasSaf Propane Tank Gas Gauge

This propane tank gauge is compatible with anything that still uses a Type 1 connection, which is already outdated as it was used more than fifteen years ago. It allows the RV to use safer propane tanks with regulators. Also, it lets older outdoor grills use modern propane tanks while enabling them to connect to propane gas lines.

I can say that it helped me a lot because I do not need to remove the tank from its position to check if there is still enough in it. I used to give the tanks a good shake to get a feel of how much fuel is still inside, but now, I just need to take a look at the dial. I could just leave the tanks mounted on the RV.

Speaking of the dial, it is large and color-coded for ease of use. If the needle is still on the green part, then the tanks will have enough in them for a couple more camping trips. If the needle is in the yellow zone, then it might have just one more trip before it runs out. If that is the case, you should at least consider getting a refill.

If the needle is in the red, then there are mostly fumes left in the tank. My favorite feature is the automatic leak countermeasure. When the gauge detects a leak in the system, it will immediately regulate the flow of propane as a safety measure. I also like that this gauge can be installed without using any kind of tool whatsoever.

• Easy to install, does not even need any tools whatsoever
• Comes with an automatic leak safety countermeasure
• Color-coded dial, which promotes ease in reading
• Made of durable brass, making the gauge weatherproof and rustproof
• Can be used as a converter for older RVs to use modern connectors
• The hand heel is very brittle, lasts only a couple months before it cracks

7. Char-Broil Propane Tank Gauge

Just like the other gauges in this list, this one can also use a Type-1 connection but can accommodate a more modern connection without any other converter. With that, you are allowed to use a propane line with a regulator if this will be used for home grills and smokers.

The dial of this gauge is also very big and somewhat easy to read. The neat thing about having this gauge installed is that I no longer need to un-mount my propane tanks and give it a good shake to figure out if there is still enough propane inside. I can now monitor it in real-time and have a replacement tank ready before the one I am currently using runs out.

I also like that there are no tools required to install this propane tank gauge. There is a plastic hand heel around the fitting of the gauge that provides a good enough grip. With that, you can install and properly tighten the gauge. There is also a dust cover that you can place on the other end if you will not be using the propane inlet valve.

I am also glad to say that you can use this gauge to determine if there is a leak in your propane hose or tank. If the needle looks like it is dropping even if you are not using any propane equipment, then there is most likely a leak. If there is a leak, the gauge will automatically lower the amount of gas that it lets through as a safety measure.

• Can be used as a converter from a Type-1 to a modern fitting
• Color-coded dial makes it easy to read; it just takes a short glance
• The dial takes into consideration the outside temperature.
• Does not need any special tool for installation
• Can be used to find if the line has any leaks
• The angle of the dial is awkward.

8. DOZYANT Propane Splitter

This propane splitter is a great solution when you have two propane-using appliances but only one tank. It is because this product allows the use of one tank and two regulators. With that, it is a cheaper alternative to buying two separate tanks. I find it great when camping.

You can connect one end to the inlet valve of the RV and the other end into your outdoor grill or stove . There is no longer any need to buy a separate tank. The dial of this gauge is pretty big and easy to read. The dial is also color-coded.

There were many times when I have been saved from going on propane run just a couple of minutes after I arrived at the campsite. The gauge considers the ambient temperature. I like this feature because doing the tank shake thing when it is hot outside does not work that well. It is because most of the propane in the tank has turned into a gas.

It is very easy to install, too. The other gauges that I have used in the past need a wrench to tighten correctly. The problem with that is that you can easily over-tighten this kind of fitting when you are using a tool. Because you can fit and tighten it by hand, you cannot over-tighten this gauge unless you are extremely strong.

• Can connect two appliances to one tank
• Has a large high-contrast dial
• Color-coded dial for easier reading
• The gauge considers the ambient temperature.
• Does not need tools to install properly
• The angle of the splitter makes it awkward to use on an RV.

9. SHINESTAR Braided NPT RV Propane Pigtail Hose with Gauge

The thing that I liked the most about this product is that it allowed me to connect a separate propane tank to my RV, and not just rely on the one mounted on the underside of the camper. It is a nice option to have if you are thinking of going on an extended camping vacation.

This gauge comes with a very durable braided hose. One amazing thing about this supply hose is that you can expose it to the elements without suffering from any kind of damage whatsoever. It will even get stronger.

The supply hose is long enough that you can easily connect an external tank to your RV’s inlet valve. The hose also has enough length to connect a tank to an outdoor grill safely. The dial is large and clear. The measurements are also color-coded to guarantee quicker and easier readings.

• Has enough hose length to connect to an RV with ease
• Gives any user the chance to use an external propane tank
• Easy to install, just needs one wrench and a bit of Teflon tape
• Has a large and color-coded dial for easy reading
• The supply hose is weatherproof and quite resistant to punctures.
• The gauge does not consider the ambient temperature.

10. Manchester Tank G12846 LP Gas Tank

This product is both a digital propane tank gauge and a remote sender. In other words, you can use it as a normal analog gauge or wire it up to a meter that is on the dashboard of the RV. With that, it will allow the user to monitor the amount of propane left in the gas tank while inside the cockpit.

It is a lot easier to install than what most people think it is. It is just screwed into the valve for the direct read gauge and the ground wire connected on any metal near the sender, and the other threaded into the dashboard-mounted meter. If you want, you can do the installation yourself. However, if you want to be extra sure, have your mechanic install it for you.

I am glad that this meter can take accurate readings. It can tell you when the tank still has a quarter left inside. I can tell when I need to have the tank refilled without having to open the access door and peek at the propane gauge.

The gauge is also made of very tough materials. The main body is made of solid brass, and the dial has a thick glass lens that can survive a couple of direct blows.

• Can be used as an analog gauge and a digital meter
• Can be installed by anyone with minimal required skills
• Made of durable materials, the main body at least
• Gives accurate readings
• No need to open the access door to check propane levels
• Very difficult to remove and reinstall on other tanks

11. Dometic LPGC10 LP Gas Checker

It is not a gas gauge per se, but it does allow for the accurate measurement of propane gas levels quickly and easily. You just place the tip of the ultrasonic propane tank level sensor on the side of the tank. If the light turns green, then it means that the propane level is up to that height. When the light turns red, there is no propane at that height of the tank.

This tool is very compact. It is just the size of a pen, so you can keep it inside of the pocket, or inside the glove box of your RV. You can also get one for use at home. Use it to check the tank on your grill or if you have an outdoor gas range. You do not need much space for this nifty little appliance.

Another thing that I liked about this propane checker is that you can use it on different kinds of propane tanks. I have used this on steel tanks, and it worked fine. Also, the manual says that it can work on aluminum tanks. Just make sure that you press the tool perpendicular to the tank side to get a more accurate reading.

My favorite benefit of this device is that it is very easy to use. Just press the end of the device onto the outside of the tank until it lights up. There are no buttons to press, no dials to twist, and no numbers to decode. You just need to wait a couple of seconds for the device to light up. If it does not, then it must mean that you are not holding the device perpendicular to the tank.

• Very small, compact, and easy to store
• Easy to use; there are no switches to flip or
• Can be used on aluminum and steel propane tanks
• Easy to decipher, no numbers or buttons to press; the color-coded dial will let you know when to buy
• Only takes a few seconds to get a reading; just make sure that the tool is perpendicular to the tank
• It can only be used accurately on 20lb tanks; anything larger will yield to wrong measurements.

12. Cuisinart CTG-200 In-line Propane Tank Gauge

Cuisinart is one of the brands that you can trust when it comes to kitchen appliances and accessories . This propane tank gauge of theirs is a winner as well. It lets the user closely monitor how much propane is still left in a 20lb tank in real-time.

This fuel gauge is very easy to install. You can easily and quickly connect this by yourself and without using any tool whatsoever. There is a built-in hand heel grip on both ends of the device that lets you connect one end to the propane tank and the other end to the regulator valve and hose.

Using this gauge will eliminate the need for the old-fashioned way of figuring out how much fuel there is in the tank, which is lifting and shaking it. It also provides a more accurate reading.

It is a very sturdy piece of hardware. The gauge itself is made of 100% solid brass and comes with thick, beefy O-rings. If you will be using this for an outdoor grill, you do not need to worry about leaving it at the mercy of the elements. It is because it will not rust.

• Very easy to install
• Can accommodate tanks up to 20lbs
• Monitors fuel levels in real-time
• The dial is big and color-coded for easier reading.
• Weatherproof and rustproof
• The gauge does not consider ambient temperature

Best RV Propane Tank Gauges Buying Guide

How Does an RV Propane Tank Gauge Work?

Propane tank gauges are inline pressure gauges. In other words, it does not work like the fuel gauge in your car. What it does, instead, is measure the amount of gasoline in the tank. A propane tank gauge measures the pressure inside the tank.

A propane tank, when full, has a lot of pressure built up inside of it. It will cause the needle of the propane tank gauge to spike up. When you start to use up the contents of the tank, the pressure will begin to drop, and so will the needle on the dial.

Usually, propane tank gauges are color-coded according to the amount of gas that is still inside the tank. Green means the tank is always full, yellow means you need to order a new tank or have the one you have refilled, and red means it would not even light up your grill.

Technically, when the pressure gauge is on the red, it does not necessarily mean that the tank is empty. There might still be a pound or so of liquid propane left inside, but that is not enough to create enough pressure to guarantee adequate gas flow through the outlet, gas line, and into the burner.

It is the reason why you need to get your tank refilled while the gauge is still on the yellow. Other propane tank gauges are not reliant on inside gas pressure at all. The most accurate ones are those that are miniature heavy-duty digital weighing scales. These are attached at the bottom of the propane tanks. They then send signals to a digital monitor at the cockpit.

Do I Need a Propane Tank Gauge for my RV?

Yes, and if you do not have it yet, you should get one as soon as you can. Your RV relies on propane for so many things – from cooking your food, keeping the refrigerator running, and keeping the interior of the vehicle comfortably warm.

If you are blissfully unaware that your propane tanks are running low, your next camping trip will be less than ideal. It is even possible for it to become horrid. Having a propane tank gauge will inform you when you need to have the tanks refilled, or if you still have enough for one more camping trip.

How to Change/Remove/Install an RV Propane Tank Gauge?

Modern propane tank gauges are pretty easy to install. If you will be using an outdoor grill, then you just have to connect the inlet fitting on the propane tank. Most gauges these days have hand heel handles. These handles allow users to connect them by only using their bare hands.

It is essential to just hand-tighten the gauge onto the propane tank. If you over-tighten the fitting, then it would strip the threading of the fitting and cause a leak. Once you install the gauge on the tank, you can then connect the other end to a gas regulator and gas line.

It is somewhat the same procedure when connecting the gauge on an RV, but you need to connect the outlet end into the input fitting of the RV and the other end to a propane tank.

How Do I Check the Level of my RV Propane Tank?

If you are from the old school crowd, the way you would measure the amount of propane left in the tank is to pick it up and give it a shake. Then you would make a rough estimate based on the amount of sloshing noises you hear coming from inside the tank. The problem with this method is that it is very inaccurate and hard on the back.

If you have a propane tank inline pressure gauge, you just need to take a peek at the dial, so you will have an idea of how much fuel is still left. The dials of propane tank gauges are often color-coded for easier reading. If the needle is in the large green zone, then that means the tank is pretty much still full.

If the needle is in the yellow zone, then it means you need to get your tank refilled. If you let your propane go down to the red zone, there is not enough pressure inside the tank to push even a bit of propane to the burner.

Some tank gauges are calibrated in such a way that they will also factor in ambient temperature when giving a reading. These gauges usually have three scale indicators. The longest one is for high ambient temperatures, the one in the middle is for cool weather conditions, and the shortest one is for cold days.

The reason for the different lengths of the indicators is that the pressure inside the tank increases when it is hot outside and decreases when it is cold.

Are Propane Tank Gauges Accurate?

If properly calibrated, inline propane tank gauges are pretty accurate. However, you will not get a definite amount from them. You will only be getting a rough estimate of the contents because these gauges rely on gas pressure inside the tank.

Another issue with inline pressure gauges is that their readings will also depend on the ambient temperature because propane expands when heated. It means that you might get a higher reading when it is hot outside compared to when it is a cooler day, but in reality, the amount of propane is still the same.

Then there are the gauges that work similarly to a weight scale. These are calibrated according to the full weight of the propane tank. These are pretty accurate when they are calibrated to work on a specific size of a propane tank.

How Long Does Propane Last in an RV?

It will depend on how much you rely on all the modern amenities of your RV. For instance, if you will be using the propane tank for grilling or whatever, then a full 20lb tank of propane might be good enough to take with you for maybe three or four overnight camping trips, with minimal use of the gas grill.

If you will be very frugal and save gas where you can, then a 20lb tank can last for an entire camping season. If you want an even more detailed computation of how long your propane tank will last, then you can use any one of the many calculators that you can find online.

You just need to find out how many BTUs of heat your propane appliances make, which you can usually find on the manufacturers’ website. If you cannot find the specific BTU of your appliances, you can search for the average BTUs those appliances create.

You just need to input the total BTUs your appliances create and the size propane tank you are using. You will then get a result telling you the total number of hours the tank will last. From that result, you can pretty much figure out how many camping trips you can get from one full tank.

How Do I Know if My RV Propane Tank is Low?

If you are not using a propane tank gauge to measure the contents of the tank, there are some signs that you need to keep an eye for. If you notice these signs, then you need to get your propane tanks charged back up.

First, you will notice that your food cooks slower than usual. If the pressure inside the propane tank starts to lower the amount of gas, then it can push through the line and into the burner. If the flames are not as high as they used to be and if they are not quite as hot as they were before, those are indicators that you will be running out of propane real soon.

Another sign that your propane is getting low is when you notice that your RV’s refrigerator is not as cold as it used to be. If your refrigerator could not even make ice cubes, then that is a clear indicator of low propane levels.

Another method involves weighing the tank using a luggage scale. First, you need to take note of the “tare weight” of the tank. It refers to the weight of the tank when empty. Weigh the tank using the luggage scale and subtract the tare weight from the value you get from the scale.

Usually, 20lb propane tanks are filled with 17 pounds of propane. If there is just a pound or so of propane left in the tank, then it is pretty much empty already.

Care and maintenance

The neat thing about propane tank gauges is that they require very little maintenance. However, they do need a bit of TLC now and then, so they will perform as expected.

First of all, you should wipe the dial of the gauge clean as often as you can. A clear dial glass will allow you to read the needle much easier. If you will be installing a gauge on your RV, make sure that the dial does not hit the access door.

Use the same damp rag to give the bronze parts of the gauge a good cleaning. You might need to provide these parts with a bit more elbow grease as dirt and dust can get into the many pits on the bronze. You do not have to polish it or anything. You just have to get it clean as much as you can.

The neat thing about inline propane tank gauges is that you can use them to tell if there is a leak on the gas lines or if there is something wrong with the regulator. If the needle on the gauge is dropping considerably, even if you are not using any of your propane appliances, then there is a leak somewhere between the gauge and the propane tank.

Buying Guide

The old-school method of measuring if there is still any propane left in the tank is to lift it and give it a shake. Aside from being tiring, it is also very inaccurate. It is better to use a gauge to get a more accurate reading of the contents of a propane tank.

Here are some of the things you have to look for when shopping for a new propane gas tank gauge:

The Type of Gauge – There are different kinds of gauges, with each one working differently. One of the types you can choose is the weight gauge. This type uses the weight of the tank to figure out how much propane is still left. It is not recommended for RVs because you will need to lift the tank and place it on the gauge to get a reading.

You can also go for pressure gauges. These units are just basic pressure gauges that measure the content of the tanks based on the amount of gas pressure inside. These types are the most popular at present.

However, they are not that accurate and prone to pressure changes due to the temperature. Also, they do not give accurate readings. They just say full, low, and almost empty. Another type is the magnetic gauge. It works by tracking changes in temperature inside the tank.

It also displays different colors depending on the level of propane left. The downside is that you need to buy a number of these gauges since their range is very short.

Lastly, there is what we call as the ultrasonic gauge. It is the most high-tech of the propane gauges. It uses ultrasonic sound waves shot inside the tank. The receiver in the gauge measures the time the sound waves bounce back and then uses that to calculate the amount of fuel left inside the tank.

Build Quality – Just like with anything else, the quality of the materials used for making the gauge, and also how the gauge was built, will significantly impact how it performs. You need to search for gauges that were made by reputable companies. Take note that they will be more expensive than other no-name gauges, but rest assured that they will be worth the extra cost.

Your Budget – Take the amount that you are willing to pay into consideration as well. Having a budget in mind will make it easier to limit the number of choices you have. It is because you will automatically eliminate the ones that you cannot afford.

However, you should not set your budget so low that you can only afford to buy cheap brands. Provide yourself with a little wriggle-room so you can still purchase the higher quality gauges.

Best RV Propane (LPG) Tank Monitor (Level Sensor)

Enjoy this article? Do us a favor and hit share!

I woke up freezing cold during a late fall camping trip, do you know why?  I ran out of propane and that caused my furnace to stop.  The inability to monitor your RV’s propane level can leave you without gas, just when you need it most.

Don’t let this happen to you too.

RVs come with all kinds of monitors and sensors.  Fresh water and sewage tank levels, smoke detectors, carbon monoxide sensors, battery monitors.  Unfortunately, one thing is missing on most RVs, a propane tank monitor.

If you aren’t lucky enough to have a rig with a factory propane monitor this process probably sounds familiar to you:

• Remove your tank cover (or open the storage bay)
• Disconnect the line to the tank’s valve
• Un-hook the bracket or tank clamp
• Lift the tank and guess how full it is

If you have done this a few times you know its’ not much fun, and unless you know the empty weight of your tank and can set it on a scale.  You are still just guessing at exactly how much propane is left.

Think for a minute about everything in your camper that runs on propane.

• Water Heater
• Refrigerator
• Outdoor Range or Grill

Being able to monitor the level of your RV’s propane tanks quickly and easily is a great way to avoid being stuck, unable to use any of those appliances.

So, how can you tell how much propane is left in the tank?

If your RV didn’t come with a level sensor and monitor from the factory there are a few great options out there.

Option 1: See-through (translucent) propane cylinders

One option is to swap out your steel propane cylinder for a composite model that allows you to see the level of the propane.  Viking is large manufacturer of composite propane cylinders.

Click here to see the Viking 17lb cylinder reviews on Amazon

Pros of composite propane tanks

• Can see propane level
• Lighter weight

Cons of composite propane cylinders

• Dimensions may not match steel
• May be difficult to have re-certified

Option 2: Propane level sensors

Before looking at the sensors on the market let’s take a quick look at the ways you can check the level in a propane cylinder and what the advantages of each are.

Types of propane level sensors

If you would rather stay with a traditional steel propane tank there are 4 common types of propane level sensors available.

• Ultrasonic Sensors
• Pressures Sensors
• Temperature Sensors
• Weight Sensors

You probably already know that propane tanks are sized by weight not volume.  Common RV sizes are 20, 30 and 40 lbs.  This is not the weight of the tank, it is the weight of propane the tank can hold.  If you have ever taken a tank to be filled, you probably noticed that the tank is filled on a scale to measure the weight of propane being added.  This makes weight one of the most accurate ways to check your tank as well.

Ultrasonic propane level sensors

Ultrasonic level sensors measure the actual level of the liquid propane in the cylinder.  They are placed on the bottom of the tank and emit a high frequency sound.  The level in the tank is calculated by measuring the time for the sound wave to reflect off the surface of the liquid propane.  Check out this Wikipedia page for more information on how ultrasonic sensors work .

Ultrasonic sensors can be monitored by a remote display or using an app on your smart phone.  This makes them ideal for RVs.

Propane tank pressure sensors

As propane is used up the pressure in the tank will decrease.  You can install a gauge between your tank and regulator that will measure the tank pressure.  This type of sensor doesn’t give an exact measurement, because the tank pressure can be affected by other things like temperature.

Pressure gauges will usually have 3 readings

There are 2 downsides to this type of sensor.  First, when it reads low, you don’t know for sure when you will run out.  Second, then cannot be remotely checked.  You have to be at the tank to see the level.

Propane tank temperature level sensors

Propane is stored as a liquid in the tank.  When propane is used it boils and comes out of the tank as a gas.  This process takes heat away from the metal tank cooling it down.  You can read more about how that happens here .  This is why you might have noticed while grilling burgers that the bottom half of your tank is covered in sweat or frost, while the top half is still dry.

Magnetic indicators are available that show where the temperate shift is at by changing color.  These indicators are usually only a couple inches tall so if you want to cover the whole tank you will need more than one.  They are around $10 so even if you purchase 4 of them for 2 tanks you aren’t out too much money.

Like the pressure gauge these have a few downsides.  They only work when you are using propane, because if the liquid isn’t converting to a gas there won’t be a temperature change.  Like the pressure gauge this indicator cannot be remotely checked.

Propane tank weight sensors

Weight is a very accurate way to measure the level in a propane tank.  You can buy scales designed to set your tank on.  You can also find spring loaded scales the tank hangs from.  The problem with this type of measurement is RV propane tanks need to be securely held in place when you are traveling down the road.  So, while weight sensors are the best choice for your back-yard grill, they don’t work well for your RV unless you plan to take them off before you travel.

If your RV is parked in a seasonal site where it won’t be moving and you can unstrap your tanks this is an option.  Just remember to secure the tanks before you move again.

Propane level indicator comparison

Below are my 4 favorite propane level indicators.  I have chosen 1 model of each type for this comparison.

Top Pick – AP Products (Mopeka) LPG TankCheck Ultrasonic LP Sensor

Click here to check pricing for the Tank Check System on Amazon

How do you check the tank level?

You can monitor the level of your tanks in 2 ways, via a smartphone app or with the standalone monitor.  Sensors can be paired with the app and the monitor at the same time, this allows the best of both options.

Tank check app

The tank check app is free and available for Android and iOS.  The app allows you to add as many sensors as you would like.  You could have 2 sensors on your RV, but you could also have one on your backyard grill or any other propane powered device.

When using the app you can setup alarms to notify you when a tank gets low.

Tank Check stand-alone monitor

The included stand-alone wireless monitor can be installed permanently in your RV and can be checked just like your water and battery monitors.  For a less permanent installation some adhesive Velcro strips could be used to mount the monitor.

The stand-alone monitor can be paired with 2 tank sensors.  The propane level is displayed with 5 LEDs for each tank.  Pressing the tank 1 or 2 button displays the level of the corresponding tank.

How long do the tank check batteries last?

The sensor and monitor are powered by a CR2032 watch style battery (don’t worry, they come with the system).  The Sensor battery life is about 1 year, the monitor should last even longer depending on how often you check the level.  If you replace the batteries each spring when you get ready for the camping season you shouldn’t have any problems.

Additional Sensors

Additional sensors are available, but only 2 can be paired to the monitor.  If you need to replace a sensor you can pair the replacement with your original monitor panel.

Tank Check System Specifications

Troubleshooting and User Impressions

• Spacers are included to make sure the weight of the tank doesn’t sit on the sensor. These were made of rubber and didn’t hold up.  They are now aluminum and are more durable.  If you have the old style you can Contact Mopeka to get the new version.
• The tank must be stationary to get an accurate reading. If the propane is sloshing around in the tank the level will not be accurate.
• Users have verified the sensors work down to -22 degrees F, but the batteries will not last long at very low temperatures.
• Placing the sensor off center can cause bad readings. The sensor has to be pointed straight up for the ultrasonic waves to properly reflect back off the surface of the liquid propane to the sensor.

Value Pick – Camco Propane Gauge/Leak Detector (Pressure Gauge)

Check the Camco Propane Gauge price on Amazon

How the Camco Gauge works

This gauge is more of a warning indicator than a level gauge.  Because pressurized propane is stored in liquid form the pressure in the tank doesn’t begin to noticeably drop off until the liquid is nearly gone.  That means this gauge will stay in the green for a while.  Then it will move quickly through the yellow and then red ranges indicating the tank needs to be refilled.

To check the gauge you have to look at it, there aren’t any fancy alarms or notifications.  When the gauge is in the green there isn’t much to worry about, but once it gets into the yellow range you should check it more often to make sure you don’t run out of LP gas.

Why is it better than other pressure style propane gauges?

Most gauges have a dial with a single scale the Camco gage has 3 scales, hot, cool and cold.  The outside temperature can affect the pressure in the tank so this eliminates the guesswork when the temperature is extremely hot or cold.

Other Options

I am including these options because in some cases you may want to use them, but for most people, I recommend choosing one of the previous models.

Original Grill Gauge

Another downside of this scale is that it is only designed for 15 and 20 lb tanks.  If your RV has a larger 30 or 40 pound tank you can still use it.  You would have mark the gauge after lifting an empty tank, because the larger tank will not read empty on this gauge.

Check the current Grill Gauge price on Amazon

GasWatch TVL214 Digital Tank Scale

Check price and reviews for the GasWatch on Amazon

GrillPro 00030 Magnetic Gas Level Indicator (temperature sensor)

2 of these indicators would be needed if you want to cover the full range of most tanks.  If you are only concerned with when the tank is getting close to empty you could just place one indicator near the bottom.  Or you could reposition the indicator as the level decreases.

This is without a doubt the lowest cost option, so if you want to give it a try, you wouldn’t be out much cash if you aren’t happy with it.

There are several reviews on Amazon stating that this indicator does not work.  I am guessing that they didn’t understand the principle behind this gauge.  If you are running a grill or stove for awhile this gauge should work just fine.

If you still haven’t decided which propane tank monitor to choose for your RV let me suggest you give the TankCheck System a try.  For around $100 it isn’t going to break the bank, but it will provide the most convenient way to monitor the level in your RV’s propane tank.  It is also the only model I reviewed that comes with everything you need to monitor 2 tanks.

If you have any of these products please leave a comment below with what you like or don’t like about it.

Thanks for sharing.Amazing content

I had an app in my previous phone where I held the phone next to my tank, hit a button, and a tone emitted which then displayed the gas level in my tank. I can’t find it anywhere now. What gives?

Ernest, I’ve never heard of that app, but if you find it please let me know. I would love to try it myself. Thanks, Jason

I got Rochester gauge brand new and still showing inside the motorhome full and on Propane tank showing half what I should do to fix it? I already replace the gauge clip on it whit 2 small wire come out of it, connect properly whit the existent wire. Please back to me Denis

Denos, I don’t have any experience with the Rochester gauge. It does sound like a wiring or electronics problem. Maybe someone else will have some advice for you. Thanks, Jason

I used the Camco Propane Gauge Leak Detector to connect to my RV propane tank so I wouldn’t be surprised next time it runs out. Works exactly as you would expect. No complaints. Just keep in mind that once it starts moving to the yellow, RUN, do not walk to the refill station. This does not work like a gas tank: it works by pressure: so once it starts to drop that low it is a lot closer to empty than you would think.

Thanks for the information. Jason

I just discovered that U-Haul sells empty 20 lb propane tanks with float gauges. Of course you’ll want to refill them, not exchange, but it’s got to be a more accurate level gauge than the temperature measurement or ultrasonic gauges, and it’s virtually free since the price is about the same as any empty tank.

Thanks, I had no idea they did that. Do you remember if they had larger tanks or was it just the 20lb size? Jason

I never know how much gas is left in the propane tanks and the last thing I want to do is run out in the middle of canning something. GASLAND is a great tool to determine when it’s time to switch the tank. It isn’t an exact measure but it gives you a general idea of whether there is enough left for the task at hand.

Previously, I always worry because I don’t know when I will run out of propane. It was too inconvenient so I bought Dozyant. Luckily it installs easily, just screws it on between the tank and the supply hose

The Camco propane tank gauge replacement is compatible with older propane inlet valves used in RVs, vessels, and propane gas grills. This is what I use on my ten-year-old RV to allow me to use modern tanks, and it works perfectly as a converter.

Your RV Holding Tank Sensors Explained

By Kelly Beasley

As you probably already know, most modern-day RVs come equipped with 2-3 camper holding tanks .

One holds fresh water, another holds sink and shower water, and one more that holds toilet waste.

These are called the RV gray water tank  (sink/shower), the camper black water tank (toilet), and the fresh tank (clean water).

There are RV holding tank level sensors that keep track of how full or empty any given tank is at any given time... or at least that is what the sensors are SUPPOSED to do.

However, more often than not, one or two of your RV waste tank sensors will mis-read due to obstructions inside the tank.

This is super common, so if you are experiencing RV tank level indicator sensor malfunction, don't stress it.

Here you will learn all about your RV holding tank sensors, how they work, and how to correct sensor issues.

Why Do I Need RV Tank Sensors?

You only need (need is a strong word) RV tank sensors when you dry camp.

Contrarily, if you camp ONLY in campgrounds with full hook-ups, you do not need tank sensors. Why? Because you'll always be connected to utilities so you don't use the tanks.

The job of a holding tank level sensor is reading how empty or full the tanks are. When you're connected to water and sewer, there's no need to fill any of your tanks for long or at all.

You benefit more from holding tank sensors if you camp without utility connections.

Because now you are self-contained. You store your wastewater inside your waste tanks. They are only so large.

Therefore, you want to know when they are getting close to empty (freshwater) or full (gray and black) so you don't run out of water or overflow your toilet or sinks/shower drain.

Let's dive a little deeper into why you don't need to use your waste tank sensors when you are in a campground with full hook-ups.

Fresh Water Tank:

Instead of filling your freshwater tank with water, you'd connect your water hose to the city water infill.

An outside water hose attachment on an RV.

Then, the water coming into your RV goes directly into the pipes, bypassing that holding tank.

Therefore, there's no filling of the tank and no need to know how much is in there.

Black Tank:

You also don't NEED your black tank sensors to tell you when your toilet tank is full.

You can either dump your black tank once a week or so, or you will 'see' or hear when it's time.

How will you see or hear it? Because your toilet either won't flush anymore, or it will 'burp' before that time comes, and boom, you know it's time to dump.

When it comes to the gray tank , if you are connected to a sewer, your can keep your gray valve open so it never fills up.

Hence, there is no need for tank sensors to tell you when you must find a dump station to go dump into.

Technically, if you ALWAYS camp with full hook-ups, you don't need to use your installed waste tank sensors.

When Do You Need To Use RV Holding Tank Sensors?

RV tank sensors are helpful when you are camping without full hook-ups, meaning when you are dry camping.

When camping like this, there's no water or sewer connection.

Therefore, your freshwater tanks hold the water you need for washing dishes, showering and that you rinse stuff with.

Your gray tank collects and holds that waste water. Your black water holding tank collects and holds the toilet water.

Now your sensors are handy to tell you when they are getting (freshwater) close to empty or getting close to full. When that time comes, it's time to dump and fill.

Two Different Sensor Types

There are two different types of holding tank sensors: probe style and capacitive style.

Probe-style sensors are by far the most commonly used in recreational vehicles. This is because they are cheap, and most manufacturers want to put the least expensive components into an RV as possible.

Probe-style sensor

Tank levels showing in thirds

These probe-style sensors protrude into the tank, passing through the tank wall. The interior portion of the sensor is what actually 'reads' the tank levels.

An electrical wire that connects to the RV tank level monitoring system will be on the outside of the probe.

Because of the way this type of sensor works , and because there are only 3-4 sensor positions in total, these systems aren't capable of giving a precise level reading. They are also susceptible to giving false readings due to contamination (as we will discuss in the next section).

A more accurate and more expensive monitoring system uses capacitive sensors mounted on the outside of the tank. There is no intrusion into the tank like probe-style sensors, so they don't suffer from the false reading issue.

Monitor showing levels in percent

These capacitive sensors also give far more accurate readings of the tank levels, displaying the levels in a percentage. They will show an accuracy of around 8%, which is a lot better than a probe sensor setup.

You will typically find this style of a sensor on upper-end recreational vehicles.

How Do RV Holding Tank Sensors Work?

The most common RV holding tank sensors work by checking if a simple electrical circuit is open (not making contact) or closed (making contact).

RV tank level sensors form a low-wattage open circuit. As long as there is no liquid or something else completing the circuit from the inside, it stays open.

Along comes liquid levels above each sensor, and that liquid completes that circuit.

So, if the fluid in the tank is up to the halfway mark, the half mark sensor closes, showing it as half full.

Each RV holding tank level indicator sensor has a wire that runs from the sensor to the RV tank level monitor panel. There, it displays the level inside each tank.

Great as that sounds, it's a flawed design, as things other than liquids can get caught on the other side of the sensor, causing a misread.

This includes toilet paper, struvites , food particles, grease, etc.

The issue is not necessarily a sensor problem. Instead, the RV tank sensors may work just fine.

It's that there is debris caught inside the tank causing the monitor to display a false reading.

To take proper care, be sure to use toilet paper safe for RV  use (better yet, don't flush your paper at all), and try to keep as much dishwashing waste (food debris and grease) from going down your drain.

There is a style of RV water tank sensor that mounts to the outside of the tank and uses electronics to measure the capacitive difference in liquid levels inside the tank.

This system is much more accurate than a traditional probe-style RV water tank level sensor but costs more, so you will typically only see it on higher-end RVs.

However, these exterior mounted RV tank gauge sensors don't collect debris like internally mounted sensors and therefore are practically immune to showing false readings.

What Is A Tank Monitor?

A tank monitor is a small electrical panel in your recreational vehicle that displays the level of your camper's tanks. (It most likely also displays information about other systems and may allow you to control certain appliances.)

The RV holding tank monitor panel receives an electrical signal from the RV water tank capacity sensors and converts that into a visual representation of the tank level.

A basic tank monitor panel

How Do You Read An RV Tank Monitor?

To read your RV tank monitor, first, you must locate yours. Some are displayed out in the open. Others are behind a cabinet door.

The monitor panel has a display that is very simple to read. Some give a percentage full; others give '1/2 full, 3/4 full,' etc.

Some are digital, and others have lights that come on next to a level when you select to see how empty or full a tank is.

RV tank monitors are very simple to read. You most likely will need to press a button to display the reading, and each tank may have its separate button.

How Do You Clean The Sensors On An RV Holding Tank?

Cleaning the sensors on an RV holding tank of goo or debris may be a little tricky. It's likely easiest in your black tank. But we shall cover both the black tank and the gray tank.

(Freshwater tank sensors rarely get contaminated with anything if you only put water into that tank, as directed.)

Read on to find out how to clean RV holding tank sensors.

How Do You Clean Grey Water Tank Sensors

You may need to clean your grey water tank sensors if they get blocked by soap scum, grease, or other residue and debris buildup on the tank walls.

To fix it, the offending stuck residue or buildup causing a reading problem needs a rinse from the walls to clear that sensor.

We believe the first method here to be the most effective solution.  But you could try the dishwashing liquid treatment  first since it is cheaper and you might have the right soap on hand.

• We like the Unique Sensor Cleaner product. It uses bacteria to dissolve all of the solids in a tank. To use, fill your tank to FULL. Add treatment. Leave at least 12 hours for everything to dissolve. Drain. Check sensors. If still reading incorrectly, repeat.
• You might try a dishwashing liquid first as a deep clean per the instructions found here . For some, this works as an effective solution.

Liquid RV Tank Sensor Cleaner

The easiest and most effective way to clean RV tank sensors is to use the Unique Sensor Cleaner product. This is especially true when it comes to cleaning RV black tank sensors.

Unique's Sensor Cleaner uses probiotic bacteria and enzymes to dissolve what is causing sensors not to read correctly. They claim it is the most powerful sensor cleaner available.

To use, fill up your tank with water to at least cover the topmost sensor. Shake the bottle of sensor cleaner and pour half of it into the tank.

You don't have to drive your RV. Instead, you just let this solution sit for at least anywhere from 12 to 72 hours (the longer, the better, usually).

Dump and rinse your black tank. Repeat the procedure if necessary.

How To Clean RV Black Tank Sensors

The process of RV black water tank sensor cleaning is similar to the grey tank. Use an enzyme or bacterial treatment as mentioned above.

The easiest way to clean black tank sensors is to use the Unique Sensor Cleaner . This liquid enzyme eats away at what is causing the sensors to read incorrectly.

Yes, it can be as easy as that!

Additionally, you can try using a wand with a sprayer to knock off the offending material on the tank walls and sensors. However, this will only work if the problem is caused by loose debris.

If all else fails, there are professional tank cleaners that will give your tanks a deep clean, including the sensors.

Marshall Uses Black Tank Sensor Cleaner

My (Marshall) black tank sensors haven't been reading correctly for years. I'm pretty sure they stopped reading accurately in the first year of ownership.

7 1/2 years later, I finally decided to see if I could get them working again. No time like the present, right?

I used 1/2 a bottle (the usual 'dose') of the Unique Sensor Cleaner product in a full black tank that I filled with fresh water.

After leaving it to sit for four days, I drained the tank, filled it with fresh water to flush it, and drained it again.

(The instructions on the bottle say to let it sit at least 12 hours, while their website suggested 72 hours, saying the longer, the better. So I went with around 96 hours just because I could.)

I observed the black tank level indication after the initial drain, filled it up, and then drained it again.

What do you know? The sensors are working as they should!

The question now is how long it will be before they stop working again? Time will tell. Overall, this was a super-simple process to get my probe-style sensors reading accurately again.

Try it if you have misbehaving sensors (the treatment won't fix electrical issues, obviously, just 'crud on the sensors' problems). It may do the trick for you as well!

Using An RV Tank Wand To Fix RV Black Water Tank Sensors

There is an RV tank wand or two manufactured to insert into your bathroom toilet.

There, the wand sprays down the interior walls. This works best if your bathroom toilet is installed directly above or near the tank mounted under it.

Find out where your toilet is from your black water tanks. If reasonably close, you can try to clean your black tank sensor using this manual method.

Just keep in mind that this method will only work if the cause of the sensor inaccuracy is loose debris and not the build-up of other material.

There's a product called the Camco Flexible Swivel Stik . This works if your toilet is close to the tank.

The product has a bendable stick, so even if your drain line has a bend in it, the tip can reach down into your tank.

Connect it to a garden hose and let 'er rip! Be VERY CAREFUL that you don't let the tank fill up and overflow.

Best to do this procedure when connected to a ground sewer outlet so you can open the RV waste valve assembly  for your black water holding tank.

This way, you cannot overflow the tank into your RV. Allow the sprayer to clean while you lower and lift the device, so you get as much coverage on the walls as possible.

Then, remove, and test your monitor and tank sensor to see if you get a correct indication.

How Do You Know When Your Holding Tank Is Full?

There are a few ways to know when a holding tank is full without using your RV tank sensors.

Black Tanks

Your black tank offers two ways to know you're close to being full sans the holding tank sensor. 

I haven't bothered with seeing how my black tank monitor reads for years now. Instead, I rely on these two things:

• You learn how long you can go on a trip before needing to dump. It stays consistent if your habits/number of people using it doesn't change.
• Your toilet(s) will announce when they are almost full. Once the sewage level starts to creep up the pipe leading from the toilet down into the tank, it will 'burp' when you flush. You'll notice it. Hard to miss this sign that your tank is very close to being full.

Your gray tank also offer ways to know they are full without using your RV holding tank sensors.

• Similar to your black tank, you will learn how long you can go on a trip before your tank is nearing full.
• Backing up. Your sink and or your shower pan will stop draining. (Usually, your shower shows first, as it's the lowest drain.) This means your tank is full. Bingo! No RV tank sensor is necessary!

How Do You Calibrate RV Tank Sensors?

Calibrating RV tank sensors is easy. This has nothing to do with the sensors not working properly.

You don't calibrate when you're getting incorrect readings. You do it when you want to change exactly WHEN the tank shows as almost full or full.

You may decide you need a few days notice before, say, your black tank is actually full.

Then, once it says full, you know you have x number of uses or days until you need to move and dump.

However, most of the lower-end brands have monitors/sensors that are not able to be calibrated.

Higher-end models MAY have monitors that can be calibrated. You know if yours are able to be calibrated if you see small holes on the monitor itself.

Neither mine nor Marshall's RV holding tanks have monitors that can be calibrated. Ours are very common and look like this:

No calibration holes

If yours does have the holes, here's how you calibrate:

Fresh Tank:

This is the easiest one.

• Fill your tank with water.
• Go inside, push fresh water tank button.
• Insert a screwdriver into the hole above the fresh button.
• It should read full. If it doesn't, turn to the right until it glows full.
• If it shows full, turn it slowly to the left until it turns off.
• Then turn it right until it glows red.

Gray Water Holding Tank

Do you really want them to have ZERO room to spare when they read full?

If you want a little bit of wiggle room, keep this in mind when calibrating.

• Fill your grey tank until the monitor says it's 3/4 full.
• Next, add water down your shower drain until your monitor reads full.
• If you want it to show only when it's ABOUT to overflow, fill until you barely see the water creeping up towards the drain.
• There, calibrate the monitor to say full.
• If you want more wiggle room, once you see the water rising, dial it forward (to the right) until it is 'over' full.

Black Water Tanks

Do this the same way you did the gray tank sensor if you want some wiggle room to know you can still go a day or so once it hits your holding tank level indicator hits the full mark.

Best to do this when connected to a sewer. (But NOT while at a dump station.)

• Fill tank until it reads full.
• As soon as your black tank says full, start adding water in one-gallon amounts at a time. And count the gallons.
• This will let you know how many gallons are truly left once it says full.
• Once you can see the liquid when you open the toilet flap, you've reached the number of gallons you had remaining.
• If you want more warning time, dial the sensor back a touch. If you wish for less warning time, dial it forward a little.

RV tank sensors aid RV owners in knowing how full or empty their tanks are.

Though people can live without them, they help keep track of your tanks when you're dry camping.

That said, the gray tank and RV black tank sensors often give incorrect readings at the monitor panel due to blocked sensors.

Sensor issues are pretty easy to resolve by using an RV sensor cleaner.

If you only camp with full hookups, you'll rarely need to use your RV tank monitor system.

But when you do dry camp, you'll be happy you have an RV tank level sensor in every tank!

If you regularly use an RV holding tank sensor cleaner, you're less likely ever to have problems with your RV holding tank monitor system.

If they don't work, don't let that stop you from getting out there and camping! Your RV tank monitor panel and sensors are a luxury, not a necessity!

I dedicated myself to living the full-time RV life for over 6.5 years, immersing myself in the unique quirks and joys of the boondocking lifestyle and gaining a wealth of knowledge and experience along the way. In December 2020, my business partner and I made the transition to part-time RVing, but in January 2023, we hit the road once again, this time in our trusty vans. My mission is to help others embrace the RVing lifestyle with confidence and excitement, armed with the knowledge and resources needed to make the most of their adventures. I believe that the more you know, the more you can truly appreciate and enjoy the freedom and flexibility of the open road.

I really appreciate the section on cleaning grey tanks. My black tank has a built-in cleaning system and it works really good. I wish manufacturers would install them on grey tanks too. I’ll try unique on my grey tank that is reading full all the time. This is a 2021 trailer I purchased last week so I don’t know what the previous owner put down the grey tank. I never had this problem on my last trailer

I disagree with leaving grey tank valves open all the time when hooked up to a campsite sewer. Water enters the tank from the top of the tank and splashes food particles, grease and other contaminants on the sides of the tank, then the water drains out leaving a nasty film on the walls that dry out and create problems with sensors and draining. I let mine fill and then drain. I’m a strong believer that water is your friend when it comes to grey and black tanks.

Good points! Yeah, it might be a best practice to keep the grey closed until one dumps. Either way, most people have problems with the sensors working after usually a short time. Most of them/us just give up. We are currently trying a new product (to us) on our new van tanks (We only have grey tanks now). We’ll see how it goes. Only been 6 months!

We hope your black tank sensors continue to work with the system you have in place and we hope your grey gets to working correctly soon.

I disagree with your methods and statements of monitors not necessary. I have bad smells when black tank full, no thanks. Also I choose to stay on top of tank levels versus worrying about them. Thanks but I will use monitors.

Yes, and to each their own! I found mine to be useless and I simply knew when my tank was getting full per how much I used it, how long it had been, and by seeing/hearing what I saw when I flushed. We’re happy to hear yours work for you, you appreciate them, and you will continue to use them. Cheers!

Best RV Propane Tank Gauges for RVs and Trailers

May 20, 2020 by RV Chick Leave a Comment

Since the majority of RVs do not have propane gauges, I recently had to research a wide variety of different gauges.  And if your RV’s refrigerator runs on propane, running out during a trip can have dire consequences for your food safety if you don’t have enough battery power to run it until you can get the tank filled.

There are some different options for propane gauges that you might want to consider for RVs and camping, particularly the feature that shows the levels based on the outside temperature.  If it is a gauge for a home BBQ, it is easy to lift the tank to see how heavy (or not) it is.  But because propane tanks are secured onto an RV, it isn’t as easy to do the quick lift test.  So I prefer the gauges with different levels depending on the outside temperature.

There are not any reliable digital propane gauges yet unfortunately.  There are some stickers that affix to the side of a propane tank as well, but they are also notoriously unreliable, not something you want to discover is wrong when in the middle of boondocking in your RV somewhere.

Camco Propane Gauge with Leak Detector

Camco is an RV brand standard, so this gauge is nearly as popular as the Flame King one, and is much easier to find in stock.  It is a much more budget friendly option as well.

On the gauge it includes markings for levels depending on the outside temperature, as the temperature outside can impact the reliability of any gauge. I prefer this one, as it is one of the only ones that takes into account the outside temperature… something that might not be as crucial for a home BBQ, but something much more important when it is powering an RV refrigerator!

It also has leak protection, adding an additional layer of safety for this valve.

After installing this one, you need to begin the propane flow before it will begin registering the propane levels properly.

• Type 1 connection for gas grills, RVs and boats

SHINESTAR Propane Tank Gauge With Temperature Settings

This is another popular propane gauge.  Like the Camco version, this one also takes into account different temperatures outside in order to get the most accurate propane levels in the tank.

• Convenient Gas Level Indicator - Effortlessly monitor the gas level in...

DOZYANT Propane Tank Gauge Level Detector

The Dozyant gauge is a popular gauge but it can be hard to find in stock due to that popularity.  It is easy to attach and is usable for propane tanks up to 40 lbs in size.  The gauge is easy to read and can be installed easily without any special tools.

This doesn’t take into account outdoor temperatures though.

The only caveat is you need to ensure there is enough room to install this, depending on where the propane is on your RV or trailer.

Camplux Propane Tank Leak Detector Gauge

Another gauge with built in propane detector.  This follows the industry standard with levels and leak detection.

Ask The RV Engineer

7 ways to measure your rv propane tank levels.

If you’ve read my guide to calculating how long your propane tanks will last, then you know estimating the answer involves math (yuck). And your forecasts will never be 100% accurate. If a 40-degree cold front blows in, you could burn through propane twice as fast as anticipated!

If you don’t want to whip out a calculator before every trip … there’s an easier way.

You would think that RV manufacturers would have automatic fuel gauges for your propane tanks. Kind of like you have a fuel gauge for your gasoline, right? Or at least something like an oil dipstick, which you can check occasionally?

Wrong. Most stock RVs don’t come with propane tank level sensors.

You gotta get your own. To whit, I have listed eight methods below. (Foreshadowing: Number 8 is my favorite!)

RV Propane Things To Know

• Propane tanks are measured by volume, not weight.
• Portable “vertical” propane tanks are certified by DOT.
• Fixed “horizontal” tanks are certified by ASME.
• Generally, steel DOT propane tanks must be recertified every 12 years.
• Common sizes are 20, 30 (33), and 40-lb tanks
• The tank poundage (e.g. 20 lbs) is the nominal weight of the propane the tank can hold when full, although the actual amount might be less to allow for expansion and pressure relief. It’s all part of the RV propane safety system.
• Your RV propane system powers your furnace, water heater, stove, oven, and absorption refrigerator.

0. Go With Your Gut

Many RVers have been camping 40 years and never, ever thought about their propane tanks. If you are a summer-only camper, a single propane tank might last you an entire year!

But it only takes one experience waking up on a November night at 3:20 a.m. with the furnace out, shivering under your covers, cursing your partner ( how could he forget to check the tanks?! ), to change your way of thinking.

1. Auto-Changeover Regulator

Most RVs nowadays come with A) at least two propane bottles and B) an automatic changeover valve propane regulator. And that little device makes all the difference.

An auto-changeover regulator drains one propane tank dry and then automatically switches to the next. Most have a red/green indicator to show which tank is empty. You simply connect both tanks to the regulator, open the valves on each tank, and let the regulator work its magic!

When the regulator detects an empty primary tank, it will switch to the other cylinder and change the indicator to red. You can remove the empty cylinder without disrupting the flow of propane; the regulator has a built-in check valve. Here’s an excellent forum description of how an automatic propane change-over regulator works.

You never know how much propane remains in your primary tank – but that’s OK. You simply know one tank is totally empty and needs refilling. So long as you keep an eye on your regulator, you’ll never run out of propane!

• Fairly inexpensive ($55-$95 for auto changeover propane regulator)
• Simple visual indicator
• Doesn’t show actual tank levels
• Requires manual monitoring
• Regulator often hidden underneath cover
• No good for RVs with only one tank

2. The Hot Water Hack

Here’s an oldie but a goodie, straight from Jeff Foxworthy’s You Might Be a Redneck If …

• This method requires a pot (about 4-6 cups) of hot water. Doesn’t have to boil (although boiling is usually alright). Lukewarm water won’t work.
• While running a propane appliance (that part is crucial!), pour a bucket of hot water over your propane tank.
• After the hot water has slightly cooled (usually just a few seconds), run your hand down the side of the propane tank. You should feel a definite temperature change somewhere on the wall. That’s the spot the liquid propane is turning into gas. That’s how full your propane tank is.

This method works because when liquid propane evaporates to a gas, it absorbs a LOT of heat. We engineers would call that the latent energy of an endothermic phase change – but yeah, no on else cares.

Sometimes, you can feel the temperature difference with a dry hand, but because water absorbs heat 25 times faster than air, it works much better!

By the way, a “full” propane tank isn’t really full. DOT propane tanks are generally filled about 80 percent by volume to allow for expansion. You aren’t being cheated; you’re being kept safe.

• Basically free
• Good party trick
• Time-consuming and annoying
• Wastes water (important when boondocking)
• Can be difficult to reach propane tanks underneath covers
• Can’t be used for propane bottles stored in compartments, like in 5th wheels

3. Magnetic Temperature Strip

These $8 strips work essentially the same way as the hot water trick: T hey detect the temperature differences on the tank sidewall.

Again, these strips have the same limitations as the hot water method: Must be manually monitored, only works while propane is running.

One isn’t long enough to cover your whole tank; you’ll need to purchase several if you want full-scale readings. Otherwise, stick it to the bottom of the tank and monitor it for when the LP gets low.

Watch for color shifts on the temperature-sensing crystals. 

• Black, Dark Blue: COLD – Liquid Propane
• Green: MEDIUM – Transition Zone
• Red, Orange: WARM – No Propane

These are also known to blow off tanks exposed to the wind. Fair warning.

• Less work than hot water method
• All cons of the hot water method
• Only measures small section of tank
• Can’t read in the dark (or direct sunlight)
• Can blow or fall off

4. Pressure Gauge

Many RVers have purchased a $20 propane tank gauge at some point in their RVing career. Most, to be honest, move on.

These gauges are not, shall we say, renowned for their accuracy. These gauges simply measure the outlet pressure of the tank, and there are several big problems with this:

• The outlet pressure (somewhat) varies depending on the rate of propane flow. So these gauges only work well when propane is being used!
• The outlet pressure varies depending on the ambient temperature. So the pressure changes if it’s a hot day or a cold day!
• The outlet pressure of a tank, all other things being equal, is mostly constant regardless of its fill level. The pressure only begins to really plummet when the tank is darn near close to empty.

So these gauges, despite their appearance, aren’t really incremental gauges. They’re empty/not-empty indicators. Once the needle falls to yellow, head for the propane store!

If you see one with a simple “Full-Low-Empty” gauge, you know it’s junk.

If you want a simple pressure gauge, get the Camco version. It has a dial indicator with levels divided by temperature (aka Cool Day, Cold Day, Hot Day).

• Effortless to install
• Works with any DOT propane tank
• Easy to read
• Not very accurate
• One gauge required for each tank
• Can’t read in the dark

5. Weigh The Tank

Weighing the tank is one of the most accurate methods.

You can weigh a tank many different ways, though.

• You can give it the ol’ bicep test: Disconnect the tank from its bracket, lift the thing, shake it around, and mutter, “Hmmm … doesn’t feel quite empty.”
• Or you loosen the tank from its bracket and lift it with a fish scale or grill gauge crane scale. Do a little math on your smartphone calculator (subtract tare weight from measured weight), and you’ll know exactly how much propane you have left.
• Or, best of all, you can use a dedicated propane scale.

Several companies, like Flame King, make halo propane scales for 20-lb, 30-lb, and 40-lb DOT portable propane tanks. You need one scale per tank. Each scale – usually shaped like a halo – is mounted underneath your tank.

These scales are wireless and battery-powered. Most connect to your smartphone through a Bluetooth connection. You’ll need to download the company’s app to monitor your tank LP levels. I don’t know of any RV tank halo scales that have a digital readout directly on the halo (it would be almost impossible to read, wouldn’t it)?

I like the idea of a weight scale, but they can present their own problems. They just aren’t compatible with many RVs.

They need a flat surface to sit on. They might not be compatible with tank bottom spacers or stabilizers.

• Remote monitoring
• Incremental gauge readings
• Need a smartphone
• Must tare different tanks (steel vs aluminum, for example)
• Not compatible with many RV designs

6. Translucent Tank

This is some next-level stuff. You can buy a composite fiberglass propane tank with semi-translucent walls. Viking and Ragasco are major manufacturers.

These tanks are … controversial, to say, the least.

Some say they’re safer because they don’t explode at high temperatures; they just melt. Some prefer them because they’re about 40% lighter than a steel tank.

Others hate ‘em. They break easily. They don’t fit the same equipment as regular propane or aluminum tanks. They cost a $100, minimum. They can’t be swapped out. They have shorter interval inspection periods. YMYL.

• Lightweight!
• Resistant to corrosion
• Easy visual inspection
• Dimensions may not match steel cylinders
• Must be recertified more often

7. Infrared Thermometer/Camera

If you’re a techno-overachiever, then I have the solution for you: Buy a thermal imaging camera. Turn on your stove. Point the camera at your propane. See how much propane is left.

It’s genius.

(It’s also $500, minimum).

The poor man’s version is a simple infrared thermometer, like you use for taking a child’s temperature. Point the thermometer at the tank to find the thermal transition zone.

I can’t, in good faith, recommend this method. I have a fragile ego, and if anyone caught me “taking the temperature” of my propane tank, I would be so embarrassed, I would shrivel up on the spot.

• Keeps your hands clean
• No remote monitoring
• Definition of overkill

7. Ultrasonic RV Propane Tank Sensors

This solution, my dear friend, is the best way to measure your propane tank levels. What you need is a battery-powered, magnet-mounted, ultrasonic propane tank sensor.

Popular manufacturers include Mopeka, Lippert, and AP Products.

These round sensors fit in the palm of your hand.

• Stick ‘em to the bottom of your propane tanks (use some double-sided tape if you dont’ trust the magnets).
• Download the manufacturer’s app.
• Connect the sensors to your smartphone or tablet via Bluetooth.
• Then you can monitor the actual amount of remaining propane anytime you want! You’ll normally need to be within about 50 feet of the sensor for it to transmit.

RV tank propane sensor is the only solution that ticks off everything we need: accurate results, incremental readings, and remote monitoring.

The AP Products Tank Monitoring system comes with its own wireless monitor, which you can install almost anywhere inside your RV! Here’s an excellent write-up I found online guiding you how to install the AP Products system.

Other systems, like the Lippert Smart Propane Tank Sensor, require a smartphone. If you’re annoyed by that fact … well, then you probably aren’t reading this paragraph. You stopped after the Hot Water Hack (which has worked well for 20 years, so why fix what ain’t broken?)

P.S. You may need a tank halo spacer or spacer feet depending on how your propane tank is mounted and which system you purchase.

• For the AP Products system, if you have a 40, 30 or 20-lb DOT propane tank, spacers are usually required. These spacers prevent the tank from crushing the wee sensor underneath!
• With the Lippert sensor, no halo spacer is required. The ultra-thin sensor won’t get squished.

Pro Tip: You can increase the interval reading time of the sensors to extend sensor battery life!

• Accurate results!
• Incremental readings
• Instant results
• (Might) require smartphone

In today’s RVing, the regulation of propane often influences various aspects of travel as many appliances on recreational vehicles happen to be gas-powered. Because of that, prior to heading out, RVers tend to think of gauges for propane tanks as must-haves. If you put a solid RV propane tank gauge on your rig, you could easily keep an eye on the gas supply, adjust operations of appliances and optimize outdoor experiences. 

With new models reaching the market from time to time, people have countless options once it comes to gauges for propane tanks of recreational vehicles. Nevertheless, if you fail to get a firm grasp on available models, you would have trouble grabbing the best propane tank gauge for your rig.

Generally, the rather wide diversity of individual liking and taste means there is no such thing as the best RV propane tank gauge for everyone. That being said, if you wish to make the most of your money, it’s suggested that you take a look at the following models.

Why This Is The Best:

Easy to set up and simple to maintain, GASPRO TG321-2 is a fantastic RV propane tank level indicator that never fails to please its users. Boasting a QCC1/Type1 connection for universal application, the gauge made by GASPRO could pair with multiple tanks between 5 and 40 pounds. In addition to that, with a color-coded dial, TG321-2 permits owners of recreational vehicles to check up on the remaining propane with relative ease. For RVers that value ease of reading, GASPRO TG321-2 is the best RV propane tank gauge at its price range.

Instead of showing the gas level as soon as installation finishes, TG321-2 only starts measuring as propane begins to flow. Since the gauge of GASPRO possesses a high level of reading accuracy, RVers would be able to soundly manage gas supply and regulate propane consumption. The minimal measurement error of GASPRO TG321-2 means it’s a snap to detect gas leaks too which is a big plus on the road. In the case that you prioritize preservations of gas, you have to consider adding TG321-2 of GASPRO to your shortlist. 

Introduced to the market at a reasonable price, GASPRO TG321-2 suits the shopping budgets of the average enthusiasts of RVing. Hence, squeezing the gauge from GASPRO into the spending plan is going to be just a walk in the park. 

We have all done it. With our small tanks that do not have a Gage. We think we have enough to do the job. Weather it be cooking or fueling your fire pit for the evening. Then it happens. Your tank is empty. At the moment I have it on a 15 pound tank, it works just as well on my 30. I have not used it on anything smaller as I have no use for them. I highly recommend this product being as how I am now a full time RVer. Shared by Daniel R.

Other models happen to be designed with regulating functions so they could double as regulators in use which eliminate the need to install separate regulators. 

Propane tank gauges for RV come in all sizes and shapes but market models could be classified into four types: pressure, weight, magnetic and ultrasonic. 

• Pressure Gauges : As propane leaves gas tanks, pressure would change and pressure gauges rely on that to measure remaining propane. Models of the types take just a couple of minutes to install and their maintenance is a breeze as well. On the downside, as the tank pressure is affected by several factors, the reading accuracy of pressure gauges is mediocre. 
• Weight Gauges : The working principle of weight gauges resemble that of pressure gauge but instead of pressure changes, they measure remaining propane using weight changes. Models of the types have decent reading accuracy so they allow owners of recreational vehicles to determine how much gas they have with reasonable precision. However, people have to spend considerable time and stamina every time they use weight gauges. 
• Magnetic Gauges : Designed to track changes in temperatures, magnetic gauges give a good account of themselves in lots of environments. Owing to the marvelous compatibility, models of the types could attach to an assortment of gas tanks with relative ease. Magnetic gauges only display readings when people use propane though. 
• Ultrasonic Gauges : By emitting high-frequency sounds that reflect off the gas tanks, ultrasonic gauges prove capable of measuring remaining propane with top-notch accuracy. Also, it’s possible to pair models of the type to mobile devices through applications so enthusiasts of RVing don’t have to go to the tanks to check readings. That being said, it may take a bit of time for owners of recreational vehicles to properly install ultrasonic gauges. 

There is no connection between the brand of a tank gauge and its field performance. Therefore, if you find a model that meets all of your criteria, feel free to buy it without bothering about which brand it comes from. Still, In the case that you care about reputability, you should remember the names below.

 How To Read Rv Propane Tank Gauge

1. Locate the propane tank gauge on your RV. It is typically mounted to one side of the RV and will be shaped like a circular disc with several numbers or lines around it.

2. Read the numbers from left to right, starting at “0” or “Empty.”. The first number you read should indicate how many gallons of propane are still in your tank (For example, 0-20).

3. Look for a smaller line between each numbered increment that indicates tenths of a gallon (For example, 1/4 = 2 1/2 gallons). If there isn’t any marker between two increments, then assume that means zero tenths of a gallon.

4. Determine where your current level falls within those numerical increments by leaning over and looking inside the tank itself; if you can see part way up the side wall then measure accordingly based on what’s visible inside the tank (For example 25% full would equal 5 gallons total).

• Locate the propane tank gauge: The propane tank gauge is typically located on the side of a recreational vehicle (RV) near the top, or it may be mounted to a bulkhead wall inside the RV
• Identify what type of gauge you have: There are two main types of gauges used for RV propane tanks – an analog dial and a digital readout. Make sure you identify which type your RV has before proceeding further so that you can interpret the readings correctly
• Check for any obstructions in view: Before reading your RV’s propane tank gauge, make sure there are no objects blocking its line of sight such as trees, shrubs, or grass clippings that could obscure its visibility from where you’re standing
• Read the Gauge: To read an analog dial-style gas meter, look at where the needle is pointing – if it’s in between two numbers then take note of both numbers and add them together; divide by two to get an accurate reading with decimal places if needed (example 1/4 + 3/4 = 2/2 = 1). For digital readouts simply record what number is displayed on screen without making any calculations necessary!

How to Read Propane Tank Level Indicator

Checking the level of propane in your tank is easy with a propane level indicator. All you need to do is locate the gauge located at the top or side of your tank, usually marked “Gauge” or “Level”. You’ll see a series of arrows that indicate how much gas remains in your tank – full on the left and empty on the right.

The further along an arrow points, the less fuel is left. If none of them are visible, then it means that your tank has been completely emptied out.

How to Read Dual Propane Tank Gauge

Reading a dual propane tank gauge is simple and easy to do. To begin, locate the two tanks that make up your propane system, as well as their respective gauges. Each should display a percentage reading between 0-100%.

This indicates how full or empty each of the tanks are; when one tank reads empty (0%), it’s time to switch over to the other full tank (100%). This will ensure you always have access to an adequate supply of fuel for your needs.

Rv Propane Tank Level Indicator

RV propane tank level indicators are a great way to keep track of the amount of propane in your RV’s gas tanks. These devices measure the volume and pressure inside the tank, giving you an accurate reading of how much fuel is left. They can also be used as part of a system that alerts you when it’s time to refill your tanks so you never run out while on the road.

Rv Dual Propane Tank Gauge

The RV dual propane tank gauge is a device that allows you to easily monitor the amount of fuel in your two propane tanks. It works by measuring the pressure inside each tank and displaying it on an easy-to-read digital display.

This ensures that you never run out of fuel unexpectedly, as you can always know exactly how much is left in each tank at any given time. The gauge also serves as a safety measure, allowing you to detect low levels of fuel before they become dangerous or cause damage.

How to Read a Propane Tank Label

Reading a propane tank label can be an important part of safely using propane for your home or business. It is important to know that the label will include safety information, such as how to correctly store and handle the tank, as well as how much propane it contains.

Additionally, the label will also provide details about its expiration date, manufacturer’s name and address, grade of fuel contained in the tank, and other pertinent information. Be sure to read all labels carefully before handling any propane tanks.

How Do I Read My Propane Tank Gauge?

Reading the propane tank gauge is a simple process that will tell you how much fuel remains in your tank. Most residential tanks have an analog dial type of gauge, which displays a numerical reading on the scale indicating how full or empty your tank is. Some tanks also have an additional low-level indicator that signals when it’s time to refill.

To read the gauge, start by locating it at the top of your propane tank and make sure that nothing is obstructing its view (such as dirt, debris or vegetation). Once you’ve established line of sight with your tank gauge, use a flashlight to illuminate the area so you can clearly see all numbers on the faceplate if need be.

Then take note of what number appears on both sides of the needle – this will give you a good indication as to whether or not there’s enough fuel left in your propane tank for continued usage.

How Do I Know If My Rv Propane Tank is Low?

If you have an RV propane tank, it is important to make sure that it stays full and properly maintained. To do this, regularly check the level of the propane in your tank so you can tell if it’s getting low. One way to do this is by inspecting the outside of your tank for a gauge or dipstick mounted near the top.

This will usually show two numbers – one indicating how many gallons are left in the tank, and another showing how much pressure is inside. If either number dips below certain levels then you know your tank needs refilling as soon as possible. Additionally, some tanks may have an alarm system installed which will sound when there’s less than 10% gas remaining in the cylinder, prompting you to refill before running out completely.

How Does an Rv Propane Tank Gauge Work?

RV propane tank gauges are an essential part of any recreational vehicle owner’s toolkit. They enable you to monitor the amount of propane left in your tank, so you can make sure that you don’t run out unexpectedly. Most RV propane tanks come with a factory-installed gauge which consists of a simple float and needle valve combination, allowing for easy monitoring.

The float is typically attached to the bottom of the tank and works by rising or lowering depending on how much gas is in it. As more gas is added to the tank, the float will rise; as gas leaves it, it will lower – this movement causes the needle valve to move up or down accordingly and provide an accurate indication of how much fuel is remaining in your tank at any given time. With regular use, these gauges help ensure that your RV never runs out unexpectedly!

What is the Best Rv Propane Tank Level Indicator?

When it comes to RV propane tank level indicator the best option is the Camco 57363 Propane Tank Level Indicator. This product works by easily and accurately telling you how much propane you have left in your tanks so that you can plan accordingly for your next stop. It features large, easy-to-read dials which allows users to monitor their gas levels at a glance without having to guess or worry about running out of fuel mid trip.

Additionally, this model is designed with an adjustable bracket which makes installation quick and easy – no tools required!

Assessing RV Propane Tanks: ASME Tank Rundown

• Description
• Discussions

On most motor homes or RVs, the ASME tank or, in layman’s terms, the RV propane tank, is responsible for fueling a number of your vehicle’s most important appliances, including the oven, stovetop burners, water heater, furnace and refrigerator. Because propane gas is required to power so many of the components you use on a daily basis when you’re touring the country in your RV, it’s important to know at least a little bit about the makeup of and proper maintenance procedures required for a standard RV propane tank in an ASME system.

To help you get to know your RV propane tank, Dave Solberg pulls back the cover on his demo vehicle’s ASME tank and discusses some expert tips for maintenance and filling that will apply to any model. He highlights a few of the important aspects of the typical RV propane tank that you should consider when taking it to your nearest certified fill station for safe filling and when monitoring it while out on the road.

What to consider when filling your RV propane tank

Dave begins the fill and maintenance process by walking you through the components on the outside of the tank, which can usually be found permanently mounted on the passenger side of your vehicle. Follow each step of the process and you’ll ensure your tank lasts forever!

One thing you should pay attention to on your RV propane tank is the proper fill level. Due to the fact that propane expands at hotter temperatures once inside the tank, OPD valves on ASME tanks only allow you to fill up to 80 percent of the total provided capacity. Tanks should only be filled by professional technicians at certified stations, where they are filled by the gallon since the tank cannot be removed to weigh it.

It’s important to note that while they are filled by the gallon, propane tanks are designated by pounds. However, trailer-mounted propane tanks are typically removed and filled by pounds as they are weighed on a scale. Propane weighs 4.2 lbs per gallon, thus an 80lb ASME tank on a motorhome could hold up to 19 gallons, however the OPD valve limits it to 80 percent, which would be approximately 15 gallons.

Additionally, users should make a note of the fact that RV propane tank covers and doors do not have locks in the event of an emergency. Located on the passenger side of the vehicle and permanently mounted to the frame of the RV, you don’t want to have to fiddle around with keys in response to a time-sensitive issue. If you have any questions about your particular model, be sure to refer to the user manual or an expert at your fill station.

Other things to keep in mind

In addition to fill limits, Dave introduces a few other aspects of ASME tank maintenance that you should consider. He teaches you the proper way to utilize the propane tank monitor on the inside of your vehicle, which allows you to keep an eye on your fill level.

Furthermore, he explains why it’s so important to turn off all pilot lights for appliances such as refrigerators, furnaces and water heaters when taking your vehicle to a certified fill station. A certified technician will almost certainly check to see you’ve done so prior to filling your tank, but it’s always recommended that you take care of this step prior to heading for the station.

And that should just about do it! Remember Dave’s expert advice for maintaining your RV’s ASME tank, and you’ll guarantee that your propane is in proper working order and you won’t run into any issues when you least expect it!

7 Responses to “Assessing RV Propane Tanks: ASME Tank Rundown”

I just bought a 2007 aljo limited and I was wondering how to light the pilot for the hot water heater??

We smell propane, furnace won’t light, alarm sounds when try to start generator? RV service not available until July 2, any ideas? Thank you, Karen

Does anyone know if replacement propane tanks are available for 1996 Roadtrek Popular, and if so where? Ours is leaking. Thank you.

My sister and husband were traveling yesterday when the pressure relief valve started leaking on the propane tank in their 1997 class c motorhome. The service center they went to for help insisted that the tank is too old to be fixed. They told them that ALL RV tanks are REQUIRED to be changed every 10 years. Their motorhome is a 1997, always stored inside, and there is surface rust on the tank. But it is the relief valve leaking. They service center is replacing the tank and all the gas lines and fittings because it has to be done every 10 years and they insist it is illegal for the just the valve to be replaced. My sister asked them just to remove the tank then and cap the lines. They refused to do so also saying it would be illegal to do also. If the tank is removed, it must be replaced with a new one. Thoughts?

Your video was OK, I would change it to show the FILLER Valve, Fixed liquid level gauge, relief valve, and then the site gauge. Explain that The Fixed liquid level gauge is required to be open while filling to prevent overfilling the tank. Relying on the site gauge or the filler valve IS NOT CORRECT. A few of the filler valves have failed in the past. Another comment is that Motor fuel tanks (Motorhome tanks) are not required to be inspected prior to filling. A good thing to know is the letters W.C. which stands for WATER CAPACITY, which is the capacity of the tank IN GALLONS. The maximum the tank should be filled is to 80% of the W.C. (I.E. 100 Gal. Tank @80% = 80 gallons propane. One last comment, some older tanks might not have the 80% shut feature, That is why you use the fixed liquid level gauge.

Are motor homes allowed in tunnels that have a 20# tank at the entrance in with the restrictions?

We always level our motor home when using it but are you saying that we also need to be sure it is level when we store our motor home until the next time we use use it?
