Second, the measuring principle:
100 h series portable ultrasonic flowmeter by using the theory of measuring the ultrasonic transmission time in the pipeline.Medium (liquid) flow velocity in the pipe, and a lag between the time of ultrasonic propagation along the downstream and upstream of medium with linear relationship.As long as measure the ultrasonic propagation time of downstream and upstream respectively, can be obtained on the basis of the linear relationship at various points along the pipeline route on the velocity of the instantaneous average flow velocity.In this way, the medium flow can be obtained by flow rate, pipe cross-sectional area and the Reynolds number.
When ultrasound beam propagation in the liquid, the flow of the fluid produces small changes will make the travel time, and the propagation time of change is proportional to the liquid flow rate, which can calculate the flow rate of the liquid.
