Abstract:
1. An ultrasonic sensor assembly for detecting a characteristic of a pipe, the ultrasonic sensor assembly including: a first transducer ring encircled to circumscribe around the pipe and attached to the pipe; a second transducer ring encircled to circumscribe around the pipe and attached to the pipe at a spaced location from the first transducer ring; and a test apparatus operatively connected to the first and second transducer rings and being configured to communicate with the first and second transducer rings; each of the first and second transducer rings being configured to transmit a first wave longitudinally along the pipe and receive a reflection of the transmitted first wave from the characteristic, the test apparatus and the first transducer ring further being configured to use results related to the reflection of the transmitted first wave to guide a second wave along the pipe that is received by the second transducer ring.
