I have a standard hand-held Benzomatic propane torch, probably 35+

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
year, I don't have a clue how much my present cylinder has been used.
Ideas ???


There are tank level indicators.

Got any for the 14.1 or 16 oz tanks like the OP is talking about?

Principle is the same and they should work on any tank. They just show
temperature at different levels. But, one of the things I tried and did
not work well. The IR thermometer mentioned sounds like a good idea but
one would cost probably more than 10 full propane bottles.
