How To Read A Propane Tank Gauge

Many propane users are confused when looking at their propane tanks. Understanding how much propane is left in your tank can save you hundreds of dollars and prevent unfortunate situations where you run out of propane. Learning how to read your propane tank gauge is very easy and useful!

Keep in mind not all propane tanks have gauges. Here’s an article on how to tell how much propane is left in a tank without a gauge. Below is a detailed step-by-step process on how to understand what your propane tank is telling you!

Step 1: Open The Lid

Start by opening the lid of your propane tank to reveal what’s underneath. There are multiple components under the lid. Here is a picture of the typical components you will see:

Step 2: Identify the Gauge

The propane tank gauge will look like a circular dial that has a red or black needle indicating the fuel level. The purpose of the gauge is to show you how much propane is left in the tank. Most gauges are “float gauges” (like a vehicle’s fuel gauge). The gauge reads the level of liquid propane in the tank utilizing a floating arm and drops as the propane level drops. Learning how to read the gauge will help you know when it’s time to request a refill.

Some things to keep in mind:

  • The numbers on the gauge represent how full the tank is as a percentage.
  • Propane expands and contracts as temperatures rise and fall.
  • Propane tanks are filled to about 80% capacity due to the natural expansion of the liquid.
  • Therefore, if your propane tank reads 80%, that means it is full.

Below is a chart to help understand how many gallons are left in your propane tank:

Gauge Reads 120-Gallon Tank 250-Gallon Tank 500-Gallon Tank 1,000-Gallon Tank
80% 96 200 400 800
70% 84 175 350 700
60% 72 150 300 600
50% 60 125 250 500
40% 48 100 200 400
30% 36 75 150 300
20% 24 50 100 200
10% 12 25 50 100

 

Step 3: Close The Lid Slowly

Close the lid of the propane tank slowly and safely while keeping your fingers out of the way.

Helpful Hints About Propane Deliveries

If you choose to monitor your own tank levels and call for deliveries when you deem necessary, try not to let the tank level drop below 20%. For homes that depend on propane as the primary heat source, the propane level can diminish very quickly if the temperature outside gets cold. Therefore, we recommend calling when your propane tank has about 30% left.
