TRANSDUCER FOR ULTRASONIC FLOW METER

摘要

An ultrasonic transducer suitable for use in ultrasonic metering of fluids at extreme temperatures. The ultrasonic transducer includes a piezoelectric crystal, low-density epoxy encasing the piezoelectric crystal, and a cylindrical reinforcing sleeve embedded in the low-density epoxy. The sleeve includes fiber mesh, and surrounds the piezoelectric crystal.
