摘　　要：超声波流量计不需要破坏管道的内部结构便可知道管道内部的液体流速,与其他流量计相比更优越。文章采用超声波“v型”时差法来测量管道内部液体的状况,利用多次脉冲法提高了测量精度,采用52单片机对流速和方向进行实时处理,测量结果能够实时显示。本装置在非侵扰流体流速测量方面具有一定的实用价值。The non-invasive nature of ultrasonic flow-meters is prominent among many flow-meters.It does not need to destroy the internal structure of the pipe to know the liquid condition inside the pipe.The ultrasonic“V-shaped”time difference method is used to measure the condition of the liquid inside the pipeline,and the multiple pulse method is used to achieve the demand of high precision.The 52 single-chip microcomputer is used to carry out micro control and calculation,and the relevant results are displayed by LCD display screen.The device can be used to measure the liquid flow rate and flow direction change in non-transparent pipes.
