How much propane is left in my tank?
Most Inline propane gauges on the market are made for large BBQ tanks and are not very efficient when dealing with small volumes of propane.
The most accurate way to find out how much propane you have left in your Gas Growler is to weigh your tank. Most propane tanks come with two numbers stamped on the handle – the water capacity (“WC” - how much water the tank could hold) and “Tare Weight” (TW – the weight of the tank when it’s empty).
To measure how many pounds of propane are left in your tank, simply weigh it on a scale (a fish or luggage scale is a great portable solution) and subtract the TW number (ours should be 9.3lbs).
1 gal. of propane weighs about 4.2 lbs., so divide the weight that the above equation comes out to by 4.2 to find out how many gallons are left in the tank.
(tank weight - TW) ÷ 4.2 = Gallons of propane left in tank
Our "5 lb." tank holds about 1.2 gal. when full.
