  • Apparatus and method of fluid level measurement
    Patent number: 6895815
    Abstract: An apparatus for fluid level measurement comprises an upright tube (10) extending into a storage tank (12) substantially the full height distance of the tank (12). An acoustic transducer (14) is positioned at the top of the tube (10) and adapted to emit a sound pulse to be bounced off the surface (16) of the fluid level within the tube (10) and to receive a reflected pulse. Means is provided for measurement of the time of arrival of the reflected sound pulse. An acoustic coupling means is provided for the transducer (14) to shape and increase the amplitude of the pulse emitted from the transducer (14) together with an increase in the amplitude of the voltage produced by the transducer (14) in response to the received reflected pulse.
    Type: Grant
