LES-01型超声波流量计利用超声波脉冲沿荷顺流方向和逆流方向传播时间的倒数之差来测定流速V,从而求得流量的值。文中分别介绍了该流量计的工作原理、主要技术指标以及性能特点,并对误差进行了分析。
The LES-01 ultrasonic flowmeter measures the flow velocity V using the difference between the reciprocal of the ultrasonic pulse in the downstream flow direction and the upstream flow direction to determine the value of the flow rate. This paper introduces the working principle of the flowmeter, the main technical indicators and performance characteristics, and the error was analyzed.
