Our local propane dealer tells me that they only true measure is by weight. That would be great if the tanks each sat on a scale in my 5er.
Cosmic is correct. When you get a tank filled, they go by weight, not volume (which is different at different temperatures). As far as I know, there is no way to determine the volume of a gas cylinder or tank by using a pressure gauge. The pressure is the same whether full or nearly empty. Just think about this - does your refrigerator, stove, water heater, etc operate any differently as the tank gets lower, by volume? No. Because the pressure is the same all the time until the tank is empty.
I've seen no gauges that would convince me otherwise.
