How can I measure the amount of LPG gas remaining in a cylinder?

use a regulator having upstream pressure guage for fully filled LPG cylinder of known volume or else the weight. Record teh initial reading on the guage. As the LPG is consumed, the reading of pressure guage decreases and weight will decreases. Record that reading. Difference between the pressure readings or weight readings will tell how much gas is remaining.

pour some hot water on the tank. You will see the line where the liquid is inside.

There should be a tare weight stamped on the collar of the cylinder. Propane (LPG) weighs 4.25 lbs per gallon, so you should weight the cylinder and subtract its tare weight to determine the net weight of of the liquid gas within. Then divide that net weight by 4.25 pounds per gallon to determine the gallons remaining in the cylinder. If the cylinder contains liquefied natural gas (LNG), then divide by 5.66 pounds per gallon.

If you weighed the cylinder when it was full, and if you know what the original contents were supposed to be, you can weigh it now to see how much is left.
