How to Read Your Propane Tank Gauge
First, you need to know the size of your tank. Then, look at your gauge, which is located underneath the hood-type cover on top of your tank. The gauge will look similar to the one shown below.
To leave room for the gas to expand, your propane tank is considered full at 80%. So, if your tank gauge reads 70% and your tank size is:
- 58 gallons, then you have 41 gallons
- 118 gallons, then you have 83 gallons
- 120 gallons, then you have 84 gallons
- 250 gallons, then you have 175 gallons
- 500 gallons, then you have 350 gallons
