What You'll Learn
Understanding the different types of gauges
Float Gauges
Float gauges are the most common type of gauge found in propane tanks. They operate similarly to the fuel gauge in a vehicle, with a floating arm that measures the level of liquid propane in the tank. As the propane level drops, the float gauge also drops, indicating the amount of propane left. While float gauges are widely used, they may not be fully reliable due to their moving parts, which can be subject to wear and tear over time.
Face or Dial Gauges
Face gauges or dial gauges are the ones that users typically interact with to determine the amount of propane in their tank. These gauges indicate the number of gallons of propane in the tank, expressed as a percentage. While they are generally dependable, they may not show the exact amount of propane and should be used for approximate measurements only.
Fixed Liquid Level Gauges or Bleeder Valves
Fixed liquid level gauges, also known as bleeder valves, are primarily used during the tank filling process. These gauges provide an accurate depiction of the propane level in the tank when refilling. The bleeder valve is designed to release liquid when the propane level reaches 80%, indicating to the delivery driver that the tank is at its maximum filling capacity.
Pressure Gauges
Propane pressure gauges are valuable tools for monitoring the pressure inside the tank. While propane is generally at a constant pressure, pressure gauges can help ensure that the pressure remains within safe limits. However, it's important to note that pressure can vary with temperature, resulting in lower pressure during cold months and higher pressure in the summer.
Weight Gauges
In some cases, weighing the propane tank can be a simple way to verify the accuracy of the gauge. By placing the tank on a scale and deducting the tare weight (stamped on the collar), you can determine the weight of the propane. Typically, propane weighs approximately 4 lbs per gallon, so dividing the total weight by 4 will give you the number of gallons in the tank.

Reading the fuel level percentage
Firstly, it is important to note that not all propane tanks have the same gauges. However, their purpose is the same: to show how much propane is left in the tank. Most gauges are ""float gauges", which use a floating arm to measure the level of liquid propane in the tank. As the level drops, so does the float gauge.
To determine the percentage of propane left in your tank, you can use the following methods:
- Calculate the number of gallons of propane remaining: This involves reading the gauge to determine the number of gallons left and then dividing the BTUs (British Thermal Units) of one gallon of propane (approximately 92,000 BTUs) by the BTU rating of your appliance. This will give you an estimate of how long the propane will last.
- Weigh the propane tank: You can verify the accuracy of the gauge by weighing the propane tank and deducting the tare weight (usually stamped on the collar) to find the weight of the propane. Since propane is typically 4 lbs per gallon, you can calculate the total number of gallons by dividing the total weight by 4.
- Use a scale or a sonar Bluetooth device: As mentioned in a Reddit post, using a scale or a sonar Bluetooth device like the Mopeka sensor can help eliminate the guesswork in determining the actual amount of propane in the tank.
- Use the hot water method: Another method suggested in the same Reddit post is to pour warm water down the side of the propane tank and then run your hand down the tank. The point at which it feels colder indicates the level of propane.
It is recommended to refill your propane tank when the fuel gauge reads 20% or below. If you use propane for home energy, it is also advised to contact your propane provider when the gauge reads 30 percent to schedule your next delivery.

Calculating how long the propane will last
To calculate how long your propane will last, you need to determine the number of gallons of propane gas remaining in your tank. Propane tanks have gauges that show the level of propane in the tank, usually as a percentage of capacity. For example, if your 500-gallon tank is showing a gauge reading of 60%, that means you have 300 gallons of gas remaining (500 x 0.6).
You can also weigh your propane tank to verify the accuracy of the gauge. Deduct the tare weight of the tank (stamped on the collar) from the total weight, and this will give you the weight of the propane. As propane is usually around 4 lbs per gallon, you can then divide the weight of the propane by 4 to get the number of gallons.
Once you know the number of gallons of propane remaining, you can calculate how long it will last by determining the BTU rating of your appliances. BTU stands for British Thermal Unit, which is a measurement used to rate how much energy it takes to produce heat. One gallon of propane contains roughly 92,000 BTUs. By dividing the BTUs of one gallon of propane (92,000) by the BTU rating of your appliance, you can calculate the number of hours it will take to use one gallon of propane. For example, if your appliance has a BTU rating of 40,000, it will take 2.3 hours to use one gallon of propane (92,000/40,000 = 2.3).
It is important to note that propane is stored as a liquid under pressure, and the pressure remains constant until you run out of liquid. The gauges measure this pressure, so they may not be accurate in determining the exact amount of propane left. Additionally, fluctuations in temperature can cause variations in the percentages displayed on the gauge. As such, it is recommended to refill your gas once your fuel gauge reads 20% or below to avoid running out of propane completely.

Determining when to request a refill
It is recommended to refill your tank when the gauge reads 20% or below. This is because, if a propane tank runs out of gas completely, air may enter the system, potentially causing damage to the tank and putting out pilot lights. This can be dangerous and may require a professional inspection before the gas can be turned back on.
To calculate how long your propane will last, you can determine the number of gallons of propane gas remaining in your tank by reading the gauge. Then, find the BTU rating of your appliances and divide the BTUs of one gallon of propane (roughly 92,000 BTUs) by the BTU rating of your appliance. This will give you the number of hours it will take to use one gallon of propane. For example, using your gas stove for one hour and 25 minutes will burn one gallon of propane.
Alternatively, you can weigh your propane tank and record the weight. By deducting the tare weight of the tank (usually stamped on the collar) from the total weight, you can calculate the weight of the propane. As propane is usually around 4 lbs per gallon, you can then divide the weight of the propane by 4 to get the total number of gallons.
You may notice fluctuations in the percentages on your fuel gauge during quick temperature swings, as propane is stored in a liquid state under pressure and expands with heat.

Verifying the accuracy of the gauge
Verifying the accuracy of a propane tank gauge is important to ensure you have enough fuel for your needs. Propane tank gauges are not always accurate, and there are several methods to check their readings.
One way to verify the accuracy of your gauge is to weigh your propane tank. You can do this by placing the tank on a scale and recording its weight. Then, deduct the tare weight of the tank, which is usually stamped on the collar, to get the weight of the propane. Typically, one gallon of propane weighs around 4-6 lbs. So, to calculate the number of gallons, divide the weight of the propane by the weight per gallon.
Another method to check the accuracy of your gauge is to use the hot water method. Pour warm water down the side of the propane tank and then run your hand down the outside of the tank. The tank will feel cold at and below the propane level and warm where there is only air. This method can help you verify the level of propane in your tank.
Additionally, you can calculate the amount of propane in your tank by multiplying the tank's capacity by the reading on the tank gauge. For example, if your 500-gallon tank shows a gauge reading of 60%, you have 300 gallons of gas remaining (500 x 0.6 = 300).
It is worth noting that propane is a compressed liquid, and the pressure in the tank remains constant until you run out of liquid. Therefore, the gauges that measure pressure are not very accurate and will only show a significant change when the tank is almost empty. Gauges with a float inside the tank are more accurate, as they show a constant pressure until the tank is empty, at which point the gauge will immediately show empty.
If you want a more precise and convenient method to verify your propane levels, you can invest in a Mopeka sonar Bluetooth device or their propane sensors. These gadgets can be installed at the bottom of your tank and provide an accurate reading without the need for manual calculations or estimations.
By using these methods to verify the accuracy of your propane tank gauge, you can ensure that you have a better understanding of your propane levels and can make informed decisions about refilling your tank.
