The working principle of ultrasonic flowmeter
The acoustic flowmeter is a non-contact instrument which has been applied in recent years, which is suitable for the fluid and large diameter flow which is not easy to be contacted for measuring and observing. The flow measurement of open flow can be carried out by linkage with water level meter. The use of ultrasonic flowmeter than not in the fluid to install the measuring elements so that the flow of fluid will not change the state, no additional resistance, installation and maintenance of instrumentation can not affect the production line operation is an ideal energy-saving flowmeter.
At present, industrial flow measurement generally exists the problem of large diameter and big flow measurement, which is because the general flowmeter will bring difficulties in manufacturing and transportation with the increase of measuring pipe diameter, the cost increase, the energy loss increase, installation not only these shortcomings, ultrasonic flowmeter can be avoided. Because all kinds of ultrasonic flowmeter can be installed outside the tube, non-contact measuring flow, the instrument cost is basically independent of the size of the pipe diameter, while the other types of flowmeter with the caliber increase, the cost increases substantially, so the caliber of the larger ultrasonic flowmeter than the same function of other types of flowmeter function price superior. It is considered to be a good large diameter flow measuring instrument, the Doppler ultrasonic flowmeter can measure the flow of two phase medium, so it can be used to measure the dirty flow such as sewer and sewage water. In power plants, it is more convenient to use portable ultrasonic flowmeter to measure the large diameter flow rate of water turbine and the circulating water of steam turbine than that in the past. Ultrasonic flow can also be used for gas measurement. The diameter range ranges from 2cm to 5m, and is available from a few meters wide nullah, culvert to 500m wide river.
In addition, the flow measurement accuracy of the ultrasonic measuring instrument is almost unaffected by the measured fluid temperature, pressure, viscosity, density and other parameters, can be made into non-contact and portable measuring instruments, it can solve other types of instruments difficult to measure the strong corrosive, non-conductive, radioactive and flammable explosive medium flow measurement problem. In addition, in view of non-contact measurement characteristics, coupled with a reasonable electronic circuit, a meter can be adapted to a variety of pipe diameter measurement and a variety of flow range measurement. The adaptability of ultrasonic flowmeter is incomparable with other instruments. Ultrasonic flowmeter has some of these advantages, so it is more and more attention to product serialization, universal development, has been made into different channels of the standard, high-temperature, explosion-proof, wet-type instrument to adapt to different media, different occasions and different pipe conditions of the flow measurement.
