Reading your propane tank fuel gauge is not complicated, but can be confusing. First, you must locate the gauge by looking under the dome of your propane tank. There you will find black numbers surrounding the circumference of the gauge and a pointer needle indicating a percentage.
Based on the physical properties of propane, tanks are considered full when the gauge reads 80%. This allows for any expansion of propane vapor. If your gauge ever falls below 20%, you should contact ThompsonGas immediately at 855-965-5577 for a refill.
It is safest to refill your tank before the gauge falls below 20%. Listed below is a handy chart to help you understand how much propane is in your tank based on readings from the gauge.
