Research on Improving the Reliability of Ultrasound Measurement

研究了一种超声波探头固定装置,并深入研究了该固定装置对超声波流量检测精度的影响。实验结果表明,随着探头固定装置载荷的增加,超声波信号幅值和传播延时随之增大并趋于稳定,流量测量的精度随着载荷量的固定而固定。该装置解决了一般非接触式超声波流量测量信号不稳定的缺点。

In this paper,a fixing device for ultrasonic probe is studied,and the effect of the fixing device on the accuracy of ultrasonic flow measurement is studied in depth.The experimental results show that the amplitude and propagation delay of the ultrasonic signal increase and tend to be stable with the increasing of the load of the probe fixing device, and the accuracy of flow measurement is stable with the fixing of the load.It solves the problem of unstable signal in general non-contact ultrasonic flow measurement.
