Is there any hardware and program to find how much gas remains in the cylinder? it will be useful for people who have only one cylinder to book for the next one before they totally run out of gas. Is it possible to find one like that?
Yes...thaz possible by measuring the weight of the cylinder. May be by an analogue or a digital weighing platform. When the gas level reduces, so will the weight. remainder will be the weight of the cylinder. Cheers
