Ultrasonic flowmeter, the English name for the Ultrasonic flowmeter, is a device that uses the principle of velocity difference to measure the flow of liquid in the tube. It can be divided into clamp type and tube type, often with digital signal processing technology, multi-pulse technology, Error correction technology, etc. are used in combination to achieve the purpose of adapting to the environment and enhancing its reliability. Now it has been widely used in the fields of chemical engineering, electric power, petroleum, and metallurgy.
Ultrasonic flowmeters are mainly composed of ultrasonic generators, ultrasonic receivers, electronic circuits, flow display, and accumulation systems. Among them, the ultrasonic generator is mainly used for generating ultrasonic waves and emitting them into the fluid; the ultrasonic receiver is mainly used for receiving ultrasonic waves passing through the fluid; the ultrasonic waves are received by the electronic circuit after being amplified, converted, etc., processed by the electric signal. The form transmits the flow to the display and displays the result; the cumulative system completes the cumulative calculation of the flow.
