采用时间差法来测水的流速，用流速乘上截面积就是流量了。 The WLV-100H handheld ultrasonic flowmeter uses the time difference method to measure the flow rate of water. Multiplying the flow rate by the cross-sectional area is the flow rate. According to the flow of water, it is divided into upstream and downstream. In simple terms, one sensor probe is installed upstream and downstream, which can transmit ultrasonic waves, upstream transmits an ultrasonic wave, and downstream reception generates a transmission time; meanwhile, the downstream sensor also transmits an ultrasonic wave The signal, the one received upstream, generates another time. The two time lengths are different, and their time difference is a function of the water velocity. In this way, the water velocity is carried on the ultrasonic wave, and the flow rate can be obtained through calculation.
