When the ultrasonic beam propagates in the liquid, the flow of the liquid will make the propagation time change slightly, and the change of the propagation time is proportional to the velocity of the liquid. At zero flow rate, the time required for the two sensors to transmit and receive sound waves is exactly the […]
