多普勒在超声波流量测量中的应用

Application of Doppler to Ultrasonic Flow Measurement

超声波流量计是流量测量中最有发展前途的三种途径之一,但目前国内外管道用多普勒超声波流量计的性能普遍不高。为了满足智能化、无接触流量测量要求,本文给出其具体实现方案,对该系统进行的实验,验证了本文提出的方法的正确性和有效性,并能够达到较高的测量精度。

Ultrasonic Flow meter is one of the most promising three methods in flow measurement .But present researches on Doppler flowmeters for pipe-flow measurement have poor performance .In order to meet the testing requirement of intelligent and non-con- tact, this paper give the project＇s software and hardware methods. The test results demonstrate the validity of all the methods pro- posed in this dissertation, and the test show that this intelligent ultrasonic flowmeter has high accuracy ~
