Bob,
In my former life, I was a process control tech [Lexan process] and our cap probe systems used 4-20 ma output which was dropped across a 250 ohm resistor to give 1-5 VDC. I'd think 1-5 V would be a good place to start. Robert Shaw, Drexelbrook were a couple of manuf that we used. Earl

If there is enough demand, and a reasonably standard output
format, I could make a circuit for measuring capacitance and
reporting it to an MFD. With only a little more effort it could
detect water or alcohol in the fuel and set an alarm. The size and
weight would be negligible compared to the sensing tube. Who would
know what output format would be appropriate?
