Those magnetic jobbies that you put on a cylinder. Can anybody tell me how they work, is it temperature?

Are they any good, and would they work on a small cartridge like a Colemane propane or CampinGaz butane?

Given that the small cartridges are never really a problem - as you should always have enough replacements to keep you going -  they are a bit academic, but appeal to me as another cool gadget to have.

The only reliable method is to weigh the cylinder.

The magnetic indicators show the point of differential temperture, but this only applies when gas is actually being drawn off at a sufficient rate.

Enough said. One for the “garbage bin of history” me thinks. Forget I ever asked.

Thanks guys.
