I don't know why you wouldn't want to have the probes in your tank. There is no electrical load on the probes nor current passing through the solution per se. The active part of the sensor is outside of the solution being measured. It is probably safer and more reliable than any "float" type of sensor and can be readily calibrated for each element of the probe for extremely accurate measurements. While I don't have them in a fuel tank, I have used this type of probe in many other applications including electroplating, rinsing, sensing, etc. etc. etc..

In that case, why not just use a site gauge. I have 7 foot long probes in my wing tanks running from root to tip of the outer wing panel. Because the tank thickness changes from root to tip, they are not linear. For wing tanks where the wing has dihedral there is no perfect system, floats or otherwise. Know what fuel you start with, know your fuel burn, and watch the clock. Larry Flesner P.S. for Robert. I'll be in Nashville on occasion as my daughter is moving there next month. I'd like to visit your project and promise not to track dirt into your sterile workshop. :-) _______________________________________________ Search the KRnet Archives at http://tugantek.com/archmailv2-kr/search.
