How To Read A Propane Tank Gauge?

To figure out how much gas is in your propane tank, use some basic math. Simply multiply the tank’s capacity by the tank gauge’s reading. For instance, if the gauge on your 500-gallon tank reads 60%, you still have 300 gallons of gas in the tank (500 x 0.6).

Propane is a popular fuel source used in many homes and businesses for heating, cooking, and other applications. For larger propane tanks, such as those used for commercial or industrial purposes, it can be more challenging to determine the level of propane remaining in the tank. However, there are several methods you can use to check the propane level in a large tank.

How to check propane level in large tank?

Modern propane tanks come with a gauge that allows you to check the amount of propane still in the tank. Check your tank’s gauge by looking for a circular dial that resembles a speedometer. It is typically found next to the fill pipe at the top of your propane tank.

Method 1: Gauge Reading

Many large propane tanks come equipped with a gauge that indicates the level of propane remaining in the tank. The gauge typically displays the percentage of propane remaining in the tank, which can help you estimate how much propane is left. To read the gauge, locate it on the tank, and look for the numbers that indicate the percentage of propane remaining. Keep in mind that gauges can sometimes be inaccurate, so it’s a good idea to use other methods to confirm the level of propane in the tank.

Method 2: Weighing the Tank

Another method to check the propane level in a large tank is to weigh the tank. To do this, you will need to know the tare weight of the tank, which is the weight of the tank when it is empty. You can find the tare weight on the tank label or by contacting the propane supplier. Once you know the tare weight, you can weigh the tank using a scale and subtract the tare weight to determine the weight of the propane remaining in the tank. Propane weighs about 4.24 pounds per gallon, so you can convert the weight of the propane to gallons by dividing by 4.24.

Method 3: Using a Dipstick

A dipstick is another tool you can use to check the propane level in a large tank. To use a dipstick, you will need to purchase or make a dipstick that is long enough to reach the bottom of the tank. Lower the dipstick into the tank until it touches the bottom, then remove it and observe the propane level on the dipstick. You can mark the dipstick with a permanent marker to indicate the level of propane remaining in the tank. Keep in mind that this method can be messy and is not always accurate.

Method 4: Ultrasonic Sensor

Another method to check the propane level in a large tank is to use an ultrasonic sensor. An ultrasonic sensor uses sound waves to measure the propane level in the tank and can provide an accurate reading without the need to open the tank or use a dipstick. Ultrasonic sensors can be purchased or rented from propane suppliers or equipment rental companies.

How to check level in a propane tank with a Gauge?

A propane tank gauge is a small device attached to the top of your propane tank. Its purpose is to tell you how much fuel is left in the tank so that you can determine when it is time to refill. Propane can be used for many different things, from generators to stoves and grills, and reading a propane tank gauge is an essential part of using it safely.

Tanks for propane are typically equipped with a gauge which can assist in determining the amount of propane that is still inside the tank. This is how you can check the propane level inside a tank using an gauge:

  1. Find your gauge: It is normally situated at one of the sides of the propane tank close to the valve.
  2. Take a look at the gauge: The gauge indicates the amount of propane left inside the tank. If the gauge reads 100%, it signifies that the tank is fully filled A reading less than 5% means the tank’s empty and requires to be filled with new propane.
  3. Be aware of any indicators that are color-coded: Certain propane tank gauges come with indicator colors that assist in determining the amount of propane left inside the tank. Green is typically a sign of a full or near full tank while red means it is empty and requires refilling.
  4. Adjust the temperature: It’s crucial to remember how propane expands or contracts when fluctuations in temperature. This could affect how accurate the gauge is, in particular in the event that temperatures have recently fluctuated. The gauge’s reading can be adjusted according to the fluctuations when necessary.
  5. Verify using other methods: Although gas tank gauges in general are accurate but it’s always an excellent idea to check the level of propane that remains in the tank by other methods, like the tank being weighed or using dipsticks.

The most common gauge is a float gauge, which uses an arm inside the tank that rises and falls with the level of liquid propane. As the float drops, the percentage indicated on the gauge decreases.

Float gauges aren’t 100% reliable because they don’t show the exact amount of fuel in the tank. The best way to know if you have enough propane is to weigh the tank and subtract its “tare weight.”

It’s a simple process that works with most tanks. Most propane tanks are stamped with a tare weight – the empty or empty pound weight of the tank when it’s complete.

When you’re ready to fill the tank, weigh the tank again and deduct that from its total weight. This will give you an accurate reading of how much propane is in the tank.

If you don’t have a float gauge, or yours isn’t working properly, you can still check the amount of gas in the tank by reading the gauge percentage. When the gauge percentage is lower than 20%, it’s time to schedule a refill.

Another option is to use a household scale. A propane tank usually weighs between 17 and 19 pounds when empty, so that a full tank will weigh somewhere between 20 and 22 lbs.

A household scale is easy to find, and it can help you measure the gallons of gas in your tank. The only downside is that it’s a bit of an investment, so you may not want to use it for your larger propane tanks.

How to read a propane tank percentage gauge?


The reading of a propane tank’s percent gauge can be a straightforward process. The gauge usually is placed on side of the tank. It comprises a dial with numbers that range from 0 to 100. These are steps that you must take:

  1. Find the propane tank’s percent gauge located on uppermost part of the tank.
  2. Check your gauge’s dial. It is generally color-coded in yellow, green and red. The green zone indicates that the tank is filled The yellow zone indicates that it’s partly full, while the red area signifies that it’s nearly empty.
  3. Use the gauge dial to find the tank’s percentage level. The percentage level is shown by the number below an indicator on gauge dial.
  4. Determine the approximate amount of propane left in the tank by calculating the percent of the level. For instance, if the gauge shows that tank half full, you can calculate that the tank is stocked with about half of the propane capacity left.

It is important to note how accurate the propane tank’s percentage gauge varies based on various factors, including the temperature and the pressure of the propane in the tank. It is always recommended that you have an alternate plan to check the level of propane for example, using an propane tank scale or tapping the sides of the tank, and listening for a sound that is hollow (indicating it is not completely empty).

You can usually find your tank’s gauge under the hood-type cover on top of your tank. It will have a dial that looks like a speedometer with numbers from 5-95.

These numbers on your gauge indicate the percentage of how much propane in your tank. To determine how much propane is left in your tank, you must multiply the gauge’s percentage by the size of your tank.

For example, if your 57-gallon tank is at 40%, you will have about 22.8 gallons of propane.

There are several ways to check your tank’s level, including using a gas monitor and calling a professional to refill the tank. But the easiest way to do this is to look at your gauge.

If your propane tank is still at 80%, call a propane delivery company to get your tank filled. This will ensure that you’ll never run out of fuel.

It’s also important to note that your propane tank gauge readings will fluctuate throughout the day. This is normal and doesn’t mean there’s a problem with your tank or gauge.

This is because propane naturally expands when the temperature outside is warmer. It will increase nearly 17 times its original volume when the temperature rises by just one degree Fahrenheit. This means that your propane gauge will read higher around noontime than at night.



If you use propane for your home heating, clothes drying, cooking, fireplaces, backup power, and outdoor living, it’s important to know how to read the gauge on your tank. Whether you have signed up for automatic delivery or you’re monitoring your tanks, knowing how to read the gauge can save you money and aggravation.

Propane is a liquid that expands and contracts to depend on the temperature of the weather. The gauge on your tank will tell you how much of it remains.

The gauge on your tank will be a round dial that looks like a speedometer with numbers from 0 to 95. It’s located under the dome lid on top of the tank. It’s also called a face gauge or dial gauge.

It can be difficult to read the numbers on a propane tank gauge, especially if you have never had one before or aren’t sure where it is. But it’s not hard to learn how to read the gauge on your propane tank and avoid a run-out.

First, you need to know how many gallons your tank is. This can be easily determined by looking at the numbers on your propane tank gauge and applying a simple math formula.

If the gauge on your tank shows that you have a 50% percentage, that means there are 125 gallons of propane remaining in the tank. This number is calculated by multiplying the percentage by the size of your tank in gallons.

Once you’ve calculated the number of gallons left in your tank, you can determine how long you will have to wait for a refill. A good rule of thumb is to call for a refill when the gauge on your tank reaches 25 percent filled or less.

When the float gauge on your propane tank shows that you have 10% of your fuel left, it is time to schedule a refill. If your tank is below 20%, it must be inspected, and a new delivery must be scheduled.
