I have a standard hand-held Benzomatic propane torch, probably 35+ years ol d. Fortunately I have never run out of gas in the middle of an important p roject, and I do have 3 hardware stores within a five minute drive. But I sometimes do projects late at nite after the stores would be closed, and it would be nice to know when my propane cylinder (~2.75" diameter, 11" long) is about to run out. I could weigh an empty cylinder, but that could be tomorrow or late next ye ar, I don't have a clue how much my present cylinder has been used. Ideas ???
