How To Read A Gauge

Your propane gas gauge is located under the dome at the top of the tank. Reading your propane gas gauge is not complicated. You’ll see bold black numbers encircling the gauge and a single pointer needle. The pointer will indicate a number that represents a percentage.

Due to the physical properties of propane, your tank is considered full at 80% (allowing for the expansion of propane vapor). A propane tank is in IMMEDIATE NEED of refilling at 20%. For your safety and protection, it is best to fill your tank BEFORE the gauge goes below 20%.

This chart shows how many gallons of propane you have in your tank at a given percentage.

TIP: Your Gauge Reads The Number of Gallons Remaining

200 Lb 420 Lb 500 Gallon 1000 Gallon
80% 48 Gal 99 Gal 400 Gal 800 Gal
70% 42 Gal 87 Gal 350 Gal 700 Gal
60% 36 Gal 74 Gal 300 Gal 600 Gal
50% 30 Gal 62 Gal 250 Gal 500 Gal
40% 24 Gal 50 Gal 200 Gal 400 Gal
30% 18 Gal 37 Gal 150 Gal 300 Gal
If a Gauge Reads less than %30.
20% 12 Gal 25 Gal 100 Gal 200 Gal
10% 6 Gal 12 Gal 50 Gal 100 Gal

If your tank size is not listed in the chart on this page, use the following formula:
Tank Size X Percentage = Gallons

Example:
A 150 gallon tank with a 50% gauge reading:
150 X .50 = 75 gallons
