Capacitive senders OTOH, I'm less sure about. Recently doing a calibration on a buddy's new build - I expected no change in reading for the last 2 gallons before full as the wing root would already be full. But there was some change in reading. Huh? Perhaps pressure change was being detected?
Mine have always been very accurate no matter how full or empty. The idea behind capacitance senders is, from what I understand, that the measured capacitance is irrespective of attitude...that it should be the same in any orientation (all the fuel in one bay, or distributed evenly across the bottom, or top, or aft, or whatever). The two plates are measuring the capacitance of the total volume between them.
