Abstract
A magnetostrictive position sensing device is disclosed where a probe assembly surrounding a waveguide is anchored at one end to the bottom of a tank and terminates in a transducer assembly attached to the top of the tank. The probe assembly compensates for differential coupling between two sections of the probe assembly. The sensing device also includes one or more fluid level floats movably surrounding a portion of the probe.
