ABSTRACT:
A magnetostrictive transducer measuring system for precisely measuring the liquid level of fuel in an underground tank. The system provides for the measurement of the position of one or more transducer magnets in a tube that are positioned along a length of the transducer wire therein, with one of the magnets fixed in the tube to provide a reference position. A current pulse is applied to the transducer wire and sonic pulses are simultaneously produced through the interaction of the magnetic field of the transducer wire and the fields of the magnets. The sonic pulses are detected by a sensor and the time interval between the detected sonic pulses is determined to determine the distance between the magnets.
