摘要:
目前的泄漏检测定位技术大多基于时间差,定位精度受时间差和声波速度的影响较大。文章采用一种基于声波幅值衰减的泄漏检测定位技术进行管道泄漏检测,实验表明,基于声波幅值衰减的泄漏检测定位技术可在不计算声速和时间差的前提下实现泄漏定位,其定位精度与衰减因子计算精度有关。
Abstract:
Most of the leakage locate method is based on the time difference, whose location accuracy is greatly affected by timedifference and acoustic wave velocity. In this study, a leakage location method based on acoustic wave amplitude was applied on theleakage location of pipe. The results show that this method can locate leakage without calculating acoustic velocity and time differenceand the locate accuracy is affected by attenuation factor calculating accuracy.
