Product Overview

External clamp type ultrasonic flowmeter basic principle is that ultrasonic waves propagate in the flowing fluid, carries

the fluid flow rate related information. Therefore, by means of the received ultrasonic sound waves, the flow velocity of the

fluid can be detected and converted into a flow rate. According to the detection method, the ultrasonic flow meter can be

divided into different types of propagation velocity difference method, Doppler method, beam shift method, noise method

and correlation method. Ultrasonic flow meter is a kind that began to be applied in recent decades with the rapid

development of integrated circuit technology, can measure fluid of almost all the clean and uniform liquid.
