Propane tank monitor

Unfortunately the gauge Pine5008 posted won't do what you want. The problem is that a propane tank is liquid on the bottom and vapor on the top. RV's pull the vapor off the top and as the vapor comes off the top the liquid boils and releases more vapor to replace what was lost.

So the gauges that hook on the regulator will only tell you that you have pressure in the tank. The pressure will be the same whether you have a full tank, half tank, or 1/4 tank. Once the tank is empty the gauge will suddenly drop from full to empty. There really isn't much in between.

You are 100% correct. I bought a pair of the gauges because they were on sale at Kohl's for cheap and wanted to see how they perform.

I find that you can read the gauges and they both read the same all the time, but when a tank is nearing empty, it will suddenly drop to the very low end of the green range and you can tell when it's almost time to refill it. And you can tell at a quick glance when a tank is empty when it's in the yellow or red zone. In 2 camping seasons, strange as it may seem, it's been working for me.

Thanks opnspaces and myredracer for giving the OP a more accurate description of the gauge. In my defense, I only acknowledge three readings on my tanks, "full, not empty, and time to go to store". For someone like the OP, that wants a accurate reading of tank level, this gauge is not the solution.
