ABSTRACT:
Ultrasonic fuel gauging apparatus for a fuel tank having a plurality of ultrasonic fuel level sensors for sensing fuel levels at respective predetermined locations in a tank based on echo ranging; a memory means for storing sensor data; and a state device for interrogating each of the sensors by controlling the application of transmit pulses to each of the sensors and for receiving output signals corresponding to return echoes, the state device operating in response to a sequential state counter.
