MGL Avionics User Forum

I have two capactive probes connected to my Odyessy G2 system. Calibration works as normal but every time i refill the fuel tanks the probes no longer read correctly. At times they are off as much as 6 gals pn an 18 gal tank. I’ve recalibrated several times but they only work for a short time before they are off again. The lower and top calibration voltage is right on the money . I can’t depend on them.

MGL does not make capacitive fuel probes.

What fuels are you using ? Note that you cannot use automotive fuels with capacitive probes. The dialectric constant of mogas is not controlled and varies wildly. These probes can only used with avgas or jet-a1.
