Abstract
An ultrasonic transducer system has at least one ultrasonic transducer. Each ultrasonic transducer includes a housing having a wall that is made at least in part of an organic structural material that is substantially impervious to water; and an ultrasonic sensor element located at least in part within the housing and positioned to transceive ultrasonic signals. The wall is preferably cylindrical in shape and made of polyvinylchloride plastic. An electrically grounded shield is within the housing and adjacent to an interior wall surface. The ultrasonic sensor element may be a piezoelectric copolymer film ultrasonic sensor element.
