摘要
文章研究了超声水流量检测换能器的工作原理和结构,从满足超声水表和超声流量计使用特性要求的角度提出了评价超声换能器性能的综合指标以及环境和介质影响量等指标,设计了配套的全性能台式试验装置。
To study the working principle and structure of the ultrasonic water flow detection transducer, a comprehensive index of evaluating performance for ultrasonic transducer is submitted. And the environment and medium impact index is proposed from the point of the application characteristics of the ultrasonic flowmeter. A complete set of full per- formance test device is designed.
