Relevant information: Measurement principle of ultrasonic Doppler flowmeter 1. Basic working principle: The measurement principle of ultrasonic Doppler flowmeter is based on the Doppler effect in physics. According to the acoustic Doppler effect, when there is relative motion between the sound source and the observer, the frequency of the sound perceived by the observer will be different from the frequency emit

ted by the sound source. The frequency change caused by relative motion is proportional to the relative velocity of two objects. In the ultrasonic Doppler flow measurement method, the ultrasonic transmitter is a fixed sound source, and the solid particles moving with the fluid act as the "observer" of relative motion with the sound source. Of course, it only reflects the ultrasonic waves incident on the solid particles back to the receiver. The frequency difference between the emitted sound waves and the received sound waves is the Doppler frequency shift of the sound waves produced less due to the motion of the solid particles in the fluid. Since this frequency difference is proportional to the fluid flow velocity, the measured frequency difference can obtain the flow velocity, and thus the fluid flow rate can be obtained. Therefore, A necessary condition for ultrasonic Doppler flow measurement is that the measured fluid medium should be a two-phase medium containing a certain number of solid particles or bubbles that can reflect sound waves. This working condition is actually one of its major advantages, that is, this flow measurement method is suitable for measuring two-phase flow, which is a problem that other flow meters cannot solve. Therefore, as a highly promising two-phase flow measurement method and flow meter, the ultrasonic Doppler flow measurement method is increasingly being applied. 2. The flow equation assumes that the angle between the ultrasonic beam and the fluid velocity is, the ultrasonic propagation velocity is c, and the velocity of suspended particles in the fluid is the same as the fluid velocity, both of which are u Taking the reflection of an ultrasonic beam on a solid particle as an example, t
