I hate to be the fly in the oitment but I had a Snake River that could never
get to work properly. In the end I believe it was due to the thickness of my
tank walls. The tank is integral to the hull and a very thick FRP layup. Great
concept that I was really hoping would be successful but in my case it was not
to be.

If the tank wall is too thich then the internal (PVC rod) sensor from Snake River
would still be an option wouldn't it? If I understand correctly this is a totally sealed
device using the same capacitance sensing technology, no moving parts, so it should
be just as immune to gumming up as the external sensor.
