Abstract
An apparatus for transmitting acoustic ultrasonic pulses and for receiving "echos" of the transmitted pulses, comprises a housing, an upstanding wall mounted on the housing defining the mouth of a well, and a transducer mounted in the housing so that the operative part of the transducer is located in the well. The well is substantially watertight and is provided with a jet for introducing water or other fluids to the well, or is pre-filled with fluid.
