Several settings use propane tanks, including residential, commercial, and agricultural. Regardless of the use, you will read the tank gauge in a similar way. Just like you would monitor the fuel level in your car, it is important to keep an eye on your propane tank gauge regularly.
The propane gas tank gauge is under the dome at the top of the tank. You’ll see bold black numbers encircling the gauge and a single pointer needle. The pointer will indicate a number that represents a percentage.
Your tank stores propane as a liquid, and it expands and contracts as outside temperatures rise and fall. We fill propane tanks to 80% of capacity, giving the fuel plenty of room to expand. A propane tank is in immediate need of a refill at 25%. For your safety and protection, it is best to fill your tank BEFORE the gauge goes below 25%.
This chart shows how many gallons of propane you have in your tank at a given percentage.
Take note of the gauge attached to the tank. Gauges with numbers from 5 to 95 indicate the percentage of gas in the tank. If your tank has a gauge that ranges from 0 to 300, this indicates pressure not percentage.
If you let your tank run empty, national safety codes require a qualified professional must inspect your propane system. Additional fees could apply.
