Abstract:
1. A magnetostrictive probe adapted to monitor liquid level comprising: an ultrasonic pulse signal detection assembly apparatus situated at the foot of the probe, a wire tensioning assembly system located in line with the waveguide inside the canister located at the top of the probe, a bottom compression assembly located inside a sealed tube, the sealed tube containing a ferromagnetic wire which is placed vertically in the tank so as to approximately reach the bottom of said container, and extend above the fill level of said container, a float for each type of liquid to be measured, whether one liquid or two or more liquids which are separated due to density differences, a magnet in each of said float(s), which interacts with magnetic fields, generated in said magnetostrictive wire by current pulses to generate ultrasonic waves that travel in both directions along said wire, a circuit which converts said wire signal to digital pulses for transmission to a central control located away from said probe assembly and which serves to analyze said data for operator presentation in usable formats, a series of temperature sensors at points along said probe for said circuit data conversion for transmission to said external control.
