Abstract
An alternate construction and method for a magnetostrictive probe intended to be used as a tank monitoring device. Height determination, either water or fuel, is referenced to an ultrasonic pickup assembly located inside the shaft at the foot of the probe. With this inverse approach, height measurement uses the relative geothermal stability of underground storage tanks, or the temperature stability offered by the thermal mass of the fuel, to facilitate a tank level determination. At that new location, the detection circuit is isolated from the effect of magnetic risers, large temperature swings and other undesirable phenomenon that often affect magnetostrictive probe measurements that are referenced to the canister. Aside from its primary use as referred to by this disclosure, this probe could be adapted for any application necessitating precise knowledge of height or distance measurement in relation to the foot of the probe without using a reference magnet.
