Ultrasonic Flowmeters
Ultrasonic flowmeters refer to a type of flowmeter developed based on the principle that the propagation speed of ultrasonic waves in a flowing medium is equal to the vector sum of the average flow velocity of the measured medium and the speed of sound waves in a stationary medium. They are mainly composed of transducers and converters, and there are different types such as Doppler method, velocity difference method, beam deflection method, noise method, and correlation method.
It is widely used in the flow measurement and control of petrochemical, steel and metallurgy, drainage, sewage treatment, and other agricultural production processes.
