How Ultrasonic Flow Meters Work

Abstract: The working principle information of ultrasonic flow meter is provided to you by excellent flow meter and flow meter manufacturers. As ultrasound waves propagate through a flowing fluid, they carry information on the fluid velocity. Therefore, the flow rate of the fluid can be detected by the received ultrasonic waves, and then converted into a flow rate. According to the detection method, it can be divided into propagation velocity difference method, Doppler method, and beam. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the working principle of ultrasonic flowmeters. As ultrasound waves propagate through a flowing fluid, they carry information on the fluid velocity. Therefore, the flow rate of the fluid can be detected by the received ultrasonic waves, and then converted into a flow rate. According to the detection method, it can be divided into different types of ultrasonic flowmeters such as propagation velocity difference method, Doppler method, beam shifting method, noise method and correlation method. Ultrasonic flowmeter is a kind of non-contact instrument that has only been used in the past ten years with the rapid development of integrated circuit technology. It can be linked with a water level gauge to measure the flow of open water. The use of ultrasonic flow ratio does not need to install measuring elements in the fluid, so it will not change the flow state of the fluid, and no additional resistance will be generated. The installation and maintenance of the instrument can not affect the operation of the production pipeline, so it is an ideal energy-saving flowmeter. As we all know, industrial flow measurement generally has the problems of large pipe diameter and large flow measurement. This is because the general flowmeter will bring difficulties in manufacturing and transportation with the increase of the measuring pipe diameter, increase the cost, increase the energy loss, Not only these disadvantages are installed, but ultrasonic flowmeters can be avoided. Because all kinds of ultrasonic flowmeters can be installed outside the pipe and non-contact flow measurement, the cost of the instrument is basically independent of the diameter of the measured pipe, while other types of flowmeters increase the cost greatly as the diameter increases, so the larger the diameter of the ultrasonic wave The function price ratio of the flowmeter is superior to that of other types of flowmeters with the same function. Considered to be a better large-diameter flow measurement instrument, the Doppler ultrasonic flowmeter can measure the flow of two-phase media, so it can be used for the measurement of dirty flows such as sewers and sewage. In power plants, it is much more convenient to use portable ultrasonic flowmeters to measure large-diameter flow such as turbine inlet water and steam turbine circulating water than the past peeling tube flowmeters. Ultrasonic flow juice can also be used for gas measurement. The applicable range of pipe diameter is from 2cm to 5m, and it can be applied from open channels and culverts with a width of several meters to rivers with a width of 500m. In addition, the flow measurement accuracy of the ultrasonic measuring instrument is hardly affected by the temperature, pressure, viscosity, density and other parameters of the measured fluid, and it can be made into a non-contact and portable measuring instrument, so it can solve the strong measurement problems that are difficult to measure by other types of instruments. Flow measurement problems for corrosive, non-conductive, radioactive and flammable and explosive media. In addition, in view of the characteristics of non-contact measurement, coupled with reasonable electronic circuits, one instrument can be adapted to measure various pipe diameters and various flow ranges. The adaptability of the ultrasonic flowmeter is also unmatched by other instruments. Ultrasonic flowmeter has some of the above advantages, so it has been paid more and more attention and is developing towards product serialization and generalization. Now it has been made into standard, high-temperature, explosion-proof and wet-type instruments with different channels to adapt to different media, different Flow measurement for occasions and different pipeline conditions. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Working Principle of Ultrasonic Flow Meter'
