Thanks for the info. I might try to replicate your circuit and see if I get the same results. I'd like to compare your sensor to the commercial one.

Another issue I have with the existing monitor in my RV is the LP gauge is not very accurate. I did find that the gauge on the tank is a 0-90ohm resistive sensor. I am not sure if it is 0ohm when empty or 90ohm when full - or vice versa.

At any rate I am thinking of perhaps replacing one of the resistors on the board in the RV with a potentiometer so I can calibrate it. But my mock up board does not have a LP function, so I would have to tinker with the one on-board.

That will not happen for awhile - at least until it is warm enough outside.
