How to Check the Propane Level

There are two ways to check the propane level in your tank:

Weigh the tank. A full propane tank will weigh more than an empty tank. You can use a kitchen scale to weigh the tank and compare it to the weight of a full tank.
Use a propane tank gauge. Propane tank gauges are available at most hardware stores. They attach to the tank and measure the pressure inside. The higher the pressure, the more propane is in the tank.
