The structure and working principle of ultrasonic flowmeter

Ultrasonic flowmeter is a kind of principle of velocity difference method is used to measure the liquid flow in pipe installation, can be divided into external clip-on and pipe sections. In the field of chemical industry, electric power, petroleum, metallurgy, etc widely used. Working principle: ultrasonic flowmeter by examining the impact of fluid flow on ultrasound to measure liquid flow, its use is 'time'. First, use the probe 1 emission signals, 1, fluid through the pipe wall, wall was on the other side of the probe after 2 to receive; In probe 1 transmitting probe 2 also send the same signal at the same time, after wall, fluid and wall 1 2 1 received by the probe; Due to the existence of the velocity of the two time ranges, lag, so according to the time difference can be obtained by flow velocity, flow value is obtained. Structure: ultrasonic flowmeter is mainly composed of ultrasonic generator, ultrasonic receiver, electronic circuit, flow display, accumulated system a few most. Among them, the ultrasonic generator is mainly used to produce ultrasonic and launch it to the fluid; Ultrasonic receiver is mainly used to accept through the fluid after ultrasonic; Ultrasound after being received by electronic circuit amplification, transformation, and so on will flow in the form of electrical signals transmitted to the display screen to display the results; Cumulative system complete flow accumulative calculation. Of the structure and working principle of ultrasonic flowmeter is to introduce you to them and if you want to know more the knowledge of the flowmeter, can focus on our website updated, or direct telephone consultation, service hotline: 15093660266.
