Propane Gauges

Just wondering how the propane gauges work on my motorhome. On is on the tank and one is in the monitor panel. Does it work on pressure? If I went to a larger tank, does the monitor panel need to be recalibrated?

Hi Courtney,

I don't know the correct answer but this is the MFG maybe they can answer your question.

The gauges operate according to level, not pressure. The propane in your tank is in liquid form. You withdraw the gas vapors from the top of the tank, which is one reason why they never fill the tank over 80%. But the real volume is the liquid within the tank.

Pressure in the tank varies with temperature and would never be an accurate method of determining volume.

There is a float switch inside the tank, just like your basic gas or diesel tank sending unit, that will rise and fall with the volume. This sending unit includes an electrical resistor so that any remote display can calculate the level and display it as well. Many OEM monitor panels have the simple Empty-1/3-2/3-Full LEDs that light up but you can connect a SeeLevel monitor panel and tap into the wire at the LP tank and get accurate readings to within 2%.

The gage on the tank can be removed as it is operated via a magnet on the float mechanism. The tank is still a sealed vessel with the gage off. The gage can be with or with out an electrical terminal. You can and probably will have to transfer the gage for your present tank to the new one.
