一种超声流量计的设计

摘要

In this paper,an ultrasonic flowmeter is designed by the use of difference method.It can measure gas flux,which can avoid the shortcoming of touching flowmeter such as short utility time and discommodious installing.It has high precision,good anti-jamming ability and bright prospects for application.%本文采用时差法设计了一种超声流量计,用于测量气体的体积流量,避免了接触式流量计寿命短、安装不方便等缺点。该设计精度高,抗干扰能力强,具有广阔的应用前景。
