Hi

Here is a page that has an article about building a capacitive fuel gauge
for homebuilt aircraft.  It should work just as well for oil.

----- Original Message ----- I'm not certain if a conductivity type probe
would work in this application. The material in the tanks is comprised of a
lot of oil which I believe is not conductive. In fact it's used as a coolant
in big transformers, etc. Am I off base here?
