ABSTRACT:
An ultrasonic transducer for emitting and receiving sound pulses is mounted within a fluid whose temperature is to be determined. The transducer is disposed in operative association with a first target which is mounted by a bimetallic coil so that it moves in a known manner with respect to the transducer in response to changes in temperature in the fluid. A stationary target is also provided disposed a fixed, known distance from the transducer, for calibration purposes. The transducer is mounted within a fiberglass tube, as are the movable and stationary targets. The tube may be mounted at the bottom of a liquid (e.g. gasoline) storage tank with the transducer facing upwardly so that both the level of liquid within the tank, and the density of the liquid as related to temperature, can be determined utilizing the transducer and a computer for acting upon the transducer output.
