Weigh the tank.
To measure how many pounds of propane are left in your tank, simply weigh it on a scale and subtract the TW number. For example, if a tank weighing 27 pounds has a TW of 17 pounds, there’s about 10 pounds of gas left – a little more than half a tank.
How do you read propane tank markings?
A propane tank’s recertification date is most often indicated by a letter instead of numbers. The letters A, B, C, and D, correspond with a quarter of the calendar year. The letter “A” would mean the tank had been recertified in January, February, or March, followed by the two numbers of the year.
What is the tare weight of a 20 pound propane tank?
Most 20 lb tanks have a tare weight of +/- 17 pounds when completely empty. This means a “full” propane tank should weigh about 37 pounds.
