摘要
超声流量计是通过检测流体流动时对超声束(或超声脉冲)的作用,以测量体积流量的仪表。文章主要讨论传播时间法、多普勒(效应)法用于测量封闭管道,液体流量的工作原理。
The supersonic flowmeter through the examination fluid flow when to ultra sound beam(or supersonic pulse) the function to apparatus of measuring volume flow.The article focused on the dissemination of time method,the law of Doppler(effect) uses in measuring tube closure, the working principle of liquid flow.
