Ultrasonic Flowmeter Related Information
Mar 23, 2018

Ultrasonic flowmeters are non-contact meters that measure both medium flow with large pipe diameters and media that are not easily accessible and observable. Its measurement accuracy is very high, almost no interference with the measured parameters of the media, in particular, can solve other instruments can not strong corrosive, non-conductive, radioactive and inflammable and explosive media flow measurement problems.

    However, ultrasonic flowmeters also have their own disadvantages in that the temperature range of the measurable fluid is limited by the degree of temperature resistance of the coupling material between the ultrasonic transducer and the transducer and the pipeline, and the measured fluid at high temperatures. The raw data of sound speed is incomplete. At present, it can only be used to measure fluids below 200°C. In addition, since the flow rate of liquid in general industrial measurement is often several meters per second, and the propagation speed of sound waves in liquid is about 1500m/s, the change in flow velocity (flow rate) of the measured fluid brings the largest change in sound speed is also 10-3. Magnitude. If the accuracy required to measure the flow rate is 1%, the accuracy of the sound velocity measurement needs to be in the order of 10-5 to 10-6. Therefore, the measurement flow of the ultrasonic flowmeter is more complicated than that of the general flowmeter.
