i don't believe you get a pressure change until just before running out
(when there's no more liquid), and by that time, it's too late.

That brings up a different question. *How come there are so many people on
the Amazon review site that say the things work? *I figure one quarter of

Not so. *I had an RV with a propane tank with a float gauge just like
an auto gas gauge.


The float guage would be accurate since it uses the fluid level inside
the tank to determine the level. Most of the guages being discussed
are not float type guages and can only measure pressure of the gas.
Your guage must be included into the construction of the container and
that is not the case with portable containers.




reliable, temperature independent way of measuring remaining gas.
