Abstract

The arrival time detection probability and the measurement range of transit-time ultrasonic flow meters are undermined by the sound drift effect. One solution to this problem is utilizing a phased-array beam steering technique to compensate the bend of the ultrasonic beams. The design, the fabrication and the characterization of two-dimensional flexural ultrasonic phased arrays is investigated in this paper. A meter body with an inner diameter of 146 mmis machined to accommodate the arrays, and flow tests are carried out at different flow rates ranging from 0 to 2500 m 3 /h. Experimental results indicate that, with the increase of flow rate, the optimum steering angle of arrays increases from 30° to 40.5° when ultrasonic beams travel upstream and decreases from 30° to 22.5° when ultrasonic beams travel downstream. This proof-of-concept design demonstrates the potential of the flexural ultrasonic phased array as an accurate, economic, efficient, and robust solution for gas flow measurement.
