ABSTRACT:
An ultrasonic fuel-gauging system has several probes each having a transducer mounted at the lower end of a still well. The transducers are connected to a processor, which measures the height of fuel above the transducers within the still wells. The processor also measures the resonant frequency of each transducer and from this calculates fuel density. The system calculates the mass of fuel in the tank from the density and the volume as calculated from the heights.
