What To Know Before Buying An RV Propane Tank Gauge


Getting the right propane tank gauge is crucial for the convenience of your road life. It all depends on a few significant factors. Here are the important things you need to remember when purchasing a gauge.

The Different Types Of RV Propane Tank Gauges

You might be unaware, but there are a few types of propane tank gauges that you should know. While ASME tanks have built-in gauges, DOT cylinders use various types of propane tank gauges. Here are the various types of propane tank gauges for RVs.

  • Horizontal Propane Tank Gauge

This type is suitable for high-capacity horizontal propane tanks. Most of these models easily snap on the crystal-shaped brass fitting on the tank’s side. Instead of color coded zones, these gauges show approximate fractions.

  • Magnetic Propane Tank Gauge

This type usually has a crystal indicator that changes color according to the temperature. When it gets heated, the color will change. The color turns back to its original state upon cooling.

However, these models tend to work well when you use plenty of gas, which is why they’re not as accurate as you expect.

  • Propane Tank Scale

This type offers decent accuracy since these gauges weigh the remaining gas in the tank. However, they require much effort to lift the propane tank when measuring it. For RVers, this can be a little inconvenient with limited space and time.

  • Pressure Propane Tank Gauge

This type is popular among RV owners because they’re a breeze to install and use. These models usually use color coded zones to indicate the different levels of gas pressure for easy reading.

However, they only show readings after the liquid propane has turned into gas, making them less accurate than propane tank scales. Nonetheless, these gauges are decent enough to show you the approximate amount of gas in your tank. Better models even take into account the changing ambient temperature for better accuracy.

  • Ultrasonic Propane Tank Gauge

This type uses a more accurate RV propane tank gauge sending unit to measure the tank’s remaining gas. These advanced models emit a sound frequency and track the total time the sound bounces back. Usually, they can be paired with a Bluetooth-enabled device to allow remote monitoring.

Sure, these units are super convenient; however, they belong to higher price points. Also, you need to charge the battery to ensure optimum performance regularly.

Benefits And Drawbacks Of Gauges For Propane Tanks

Utilizing an external gauge for your propane tank comes with both benefits and drawbacks. This part will discuss both sides to help you make a wise decision. Let’s begin with the benefits to help you understand why you should consider getting a gauge.

  • Tells You When To Refill: The main advantage of using a gauge is to determine the approximate gas amount left in your tank. No more guessing and running out of fuel at a bad time. With the color coded dials, it’s easy to see when you need to get a refill.
  • Quick To Install: These RV tank gauges are so easy to install because they don’t need tools. Just simply hook the gauge to the tank and tighten the connection. Most of these models come with a handwheel grip, which is easy to turn by hand.
  • Easy To Use: These gauges often come with color coded dials to show how much fuel is left on the tank. The dial usually shows three color zones: green (sufficient), yellow (low), and red (refill). When the dial hits the yellow zone, you must consider getting a refill to avoid interrupting the function of your hooked propane appliance.

Some gauges even connect to your smartphone via Bluetooth. These ultrasonic models monitor your tank’s contents within a specific range. For example, Tank Check LP shows the tank’s status as far as 50 feet.

  • Economical: Since these gauges tell you the approximate propane amount, they allow you to consume the tank wholly. Some gauges also come in Y-splitter forms allowing you to connect two propane appliances into a single tank.

On the other hand, here are a few downsides that you should be aware of when using a tank gauge.

  • Inconsistent Readings: Sometimes, readings may be inconsistent due to varying temperatures of the surroundings. During cold days, the pressure drops and shows less amount of fuel. Conversely, the warmer days seem to provide more accurate readings.

To avoid this problem, consider getting a unit that takes into account the varying ambient temperature. These models often have three different bars, representing different temperatures: cool, cold, and hot.

  • Possible Leaks: When you fail to tighten the connection between the propane tank and the appliance, there’s a chance that some gas might leak. To avoid this problem, use a pipe thread tape to secure the connection or opt for models with leak detection features.

Features To Look For On A Good Propane Tank Gauge

Buying a new propane tank gauge is easy if you know what things to look for. Here are important features to check before making that purchase decision to help you with your shopping needs.

  • Material

The best RV propane tank gauges are made of solid materials, like brass. Not only does brass look high class with its gold color, but it’s also resistant to corrosion. This material remains durable even if it tarnishes over time.

  • Ease Of Reading

Considering that the RV tank gauge’s main purpose is to monitor the gas supply, it’s only right that you pay much attention to ease of reading. The top-tier models provide color codes to indicate the propane level. Even from a glance, you’ll know right away what the gauge is telling you.

Usually, green means sufficient, while yellow means that you’re running low on gas. The red zone means that the tank is almost empty, so you better get a refill fast. In some models, they even make the dial glow in the dark to aid in nighttime use.

  • Compatibility

You want your gauge to have a universal fitting to connect to all types of gas tanks, regulators, and other propane appliances for versatility. Some of the top-quality models can fit all QCC1/Type 1 connection. Of course, the tank capacity also matters.

If you constantly use heavy propane tanks, ensure that the gauge suits 40-lb tanks at least. Regulator users can opt for gauges that can hook to 20-lb tanks.

  • Warranty

For your peace of mind, check the product’s warranty. Good tank gauges offer at least a 1-year warranty, while others go as far as offering a lifetime warranty. If possible, look for a longer warranty to have more confidence in the product’s quality.

You also need to check the warranty coverage to ensure that you get covered. Some manufacturers might be vague about these policies, so it’s wise to be meticulous on this part.

  • Extra Features

If you want to use your gauge outside the RV, look for a dust cap to protect the unit from any road debris. Safety features, like excess flow protection, ensure that you’re protected from gas leaks. Other models even offer thermal protection in case of fire.

DOZYANT makes top-tier propane tank gauges because they offer different types, such as a Y-splitter and a model that takes into account the changing surrounding temperature. Their basic model has the typical color indicators to show full, low, and empty.

AP Products offers top-rated ultrasonic gauges, like the Tank Check LP. This modern gauge uses Bluetooth to send details about the propane status directly to your smartphone. When it comes to price, Kohree is a reliable brand.

Most magnetic propane tank gauge reviews hail Master Chef as a great brand under this category. Magnetic Chef creates its magnetic propane indicator in different colors. It tries to measure propane in different seasons as possible.

How does an RV propane tank gauge work?

Instead of the propane level, these gauges rely on pressure to read the remaining gas in your tank. More specifically, these units measure the gas pressure being pushed out into the propane appliance’s hose. These products won’t take readings until you open the tank valve for gas flow.

Once you install the gauge on your propane appliance, you’ll notice that the dial points to the sufficient or green zone. The gauge will only start moving into the yellow zone once the propane tank is left with a quarter. You may still cook for one or two meals, but the gas flow has reduced, and it’s the right time to get your tank refilled.

When the dial points to the red zone, it means that the tank is almost empty. The propane is barely usable at this point because there’s not enough propane to pressurize and drive through the hose.

Are RV propane tank gauges accurate?

Yes, these gauges are pretty accurate, especially during regular or warmer temperatures. Reliable models can give the proper approximation of gas left on your tank. Though these pressure gauges may not be as precise as propane scales, these models are good enough to know when you need to get your next refill.

If you want accurate readings all season long, consider getting a model that factors in the varying ambient temperature. As you see, gas pressure drops during cold days, so the reading will show half empty on a basic model.

How to read RV propane tank gauges on a camper?

It’s easy! Just look at the different color codes. When the dial’s needle points to the green zone, it means the tank is full or sufficient. Pointing to the yellow zone means that the tank is running low on gas. The red zone means that the tank is almost empty, and you need to get a refill quickly.

Gauge models that consider the changing ambient temperature often have three bars to represent cold, cool, and hot days. Depending on the weather, find out where the needle is pointing and use the same color interpretations above.

What size are most RV propane tanks?

RV propane tanks usually come in 20 lbs, 33 lbs, 100 lbs, and 420 lbs. The 20-lb tank is usually 18 inches high and can hold about 5 gallons of propane. These lightweight tanks are popular choices for barbecues and grills.

The 33-lb tanks can hold about 8 gallons of propane. They’re slightly heavier than 20-lb tanks, but a single individual can still carry them.

On the other hand, 100-lb tanks can accommodate about 25 gallons of propane, while a 420-lb tank can fill about 100 gallons of propane. Both these tank sizes are heavy, so they might need a hand in carrying them.

How to set up and use?

The first thing you do is turn the gas off the tank. If your tank is stored under a barbecue grill, take it out for easy installation. Now that the tank is out of the grill, check whether the valves are closed. You might hear some hissing sound, but that’s normal because of the gas released when you unscrew the regulator.

Next, take the inline tank gauge and connect it to the propane tank. Hold it straight and tighten it down using the handwheel grip. Once tightened, put the regulator back on and tightened. You want the gauge positioned where you can see the dial clearly.

Now, open the valve, and the needle should move. The dial turns to the yellow zone when the propane tank is left with around 5 lbs. When this happens, make sure to get a refill to be safe.

Are all propane tank gauges the same?

No, not all propane tank gauges look similar. Since they’re made by different manufacturers, they may come in different sizes, styles, and features. We have digital propane gauge and smart propane tank gauge models that adopt wireless technology for convenience.

Most gauges use a large propane tank level indicator to tell you the remaining gas. Meanwhile, modern models use Wifi to allow you to monitor the gas levels in your phone.

While these gauges may not look the same, they serve the same purpose—to measure how much propane is left in your tank.

How much does 1 lb of propane weigh?

A pound of propane still weighs 1 lb. It only becomes a different story if you’re talking about a 1-lb tank because you need to consider the empty tank’s heft, around 14 ounces or 0.875 lb. Subtract 1 lb to 0.875 lb, you’ll get the actual weight of the propane—0.125 lb.

A gallon of propane weighs about 4.2 lbs at room temperature. Let’s say you have a 7 gallon propane. The weight will be 7 × 4.2 = 29.4 lbs. If you want to upgrade to a tank that can hold 100 pounds of propane, you’ll have to buy a 170-pound tank (70-lb empty tank plus 100-lb fuel).

At what percentage should I refill propane tank?

When you see that your propane tank digital gauge has almost reached 20%, it’s time to refill your propane tanks. Never let the tank fall below 20% because it can lead to serious problems, like refill leaks and rust. The latter issue is particularly serious, as it can hinder the detection of gas leaks.

Where can I fill propane near me?

Once your propane tank measuring device informs you that your tank needs a refill, call a good propane company or visit a propane refill station. Use a location finder to find the nearest station near you, or just type “propane service near me” in the Google search bar with location on.

If you’re near Costco, head there because they offer the most reasonable prices of propane. Some stores that might offer a propane refill include truck rental companies and local suppliers.


That wraps up our propane tank gauge review. If I have to pick the best RV propane tank gauge, my choice would be the DOZYANT 812-9229-S because it’s the most accurate during normal or warmer days. This unit is fairly priced, safe, and durable.

If you want to check the propane levels of more than one propane tank, GasSaf and CHULAN 2-pack gauge models are your best choices. The DOZYANT and Kohree Y-splitters are perfect for monitoring the propane levels of two propane appliances from a single tank. I recommend WADEO and GasPro as their gauges provide different gas pressure levels during cool and cold days for more accuracy.
