The difference between Doppler ultrasonic flowmeter and time difference ultrasonic flowmeter

　　So what is the difference between these two types of ultrasonic flow meters? Let’s take a look together with Supmea.

　　The first type: Doppler ultrasonic flowmeter uses the phase difference method to measure flow velocity, that is, a sound wave of a known frequency moves in the fluid. Since the liquid itself has a moving speed, the frequency or phase of the ultrasonic wave between the two receivers (or transmitters) changes relatively. By measuring this relative change, the liquid velocity can be obtained; the second type: time difference ultrasonic flowmeter uses the time difference method to measure flow velocity, that is, a sound wave of a certain speed changes its propagation time between the two receivers (or transmitters) due to the flow of the fluid. By measuring this relative change, the fluid flow velocity can be obtained. At present, the time difference ultrasonic flowmeter is used.
