摘要： An ultrasonic sensor assembly includes a flexible supporting material that has flexibility configured for allowing bending of the supporting material to conform to a cylindrical shape of a pipe. The assembly includes a plurality of operable sensor elements arranged in a matrix formation upon the flexible supporting material.

摘要： Systems and methods are disclosed herein in which multi-level square wave excitation signals are used instead of or in addition to fully-analog excitation signals to drive an array of transceiver elements to create a sound field. Use of multi-level square wave excitation signals produces acceptable transceiver output with reduced complexity, cost, and/or power consumption as compared with use of fully-analog excitation signals. In addition, use of such signals facilitates system implementation using application-specific integrated circuits (ASICs) and is not as restricted in voltage level and speed. At the same time, the benefits and applications of fully-analog excitation signals (e.g., acoustic holography, beam superposition, signal-to-noise ratio (SNR) improvements, suppression of parasitic modes, increased material penetration, potential for coded pulsing algorithms and suppression of side lobes in ultrasonic field) can still be achieved with multi-level square wave excitation signals.

摘要： An ultrasonic sensor assembly detects a characteristic of a pipe. The ultrasonic sensor assembly includes first and second transducer rings spaced apart along a length of the pipe. Each of the first and second transducer rings can transmit a first wave longitudinally along the pipe and receive a reflection of the transmitted first wave from the characteristic. The first transducer ring can 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. Methods of detecting a characteristic of the pipe are also provided.
