Abstract: The principle and application information of ultrasonic flow meter are provided to you by excellent flow meter and flow meter manufacturers. Fundamentals of Ultrasonic Flow Meters Fundamentals and Types of Ultrasonic Flow Meters Ultrasonic waves carry information on fluid flow rates as they propagate through a flowing fluid. Therefore, the flow rate of the fluid can be detected by the received ultrasonic waves, and then converted into a flow rate. . More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are details of the principle and application of ultrasonic flowmeters. Fundamentals of Ultrasonic Flow Meters Fundamentals and Types of Ultrasonic Flow Meters Ultrasonic waves carry information on fluid flow rates as they propagate through a flowing fluid. 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. Acoustic wave flowmeter is a kind of non-contact instrument that has been applied with the rapid development of integrated circuit technology in the past ten years. 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, the current 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, and the cost will increase and the energy loss will increase. Not only these shortcomings, but also the ultrasonic flowmeter 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 current shortcomings of ultrasonic flowmeters are mainly that the temperature range of the measurable fluid is limited by the temperature resistance of the ultrasonic transducer aluminum and the coupling material between the transducer and the pipeline, and the original data of the sound transmission velocity of the measured fluid at high temperature. incomplete. At present, my country can only be used to measure fluids below 200 ℃. In addition, the measurement circuit of the ultrasonic flowmeter is more complicated than that of the general flowmeter. This is because the flow velocity of the liquid in general industrial measurement is often several meters per second, and the propagation velocity of the sound wave in the liquid is about 1500 m/s. 3 orders of magnitude. If the accuracy of measuring the flow rate is required to be 1%, the measurement accuracy of the speed of sound needs to be in the order of 10-5 to 10-6, so there must be a perfect measurement circuit to achieve this. The reason why the technology can be practically applied under the premise of the rapid development of technology. Ultrasonic flowmeter consists of three parts: ultrasonic transducer, electronic circuit and flow display and accumulation system. The ultrasonic transmitting transducer converts electrical energy into ultrasonic energy and transmits it into the fluid to be measured. The ultrasonic signal received by the receiver is amplified by the electronic circuit and converted into an electrical signal representing the flow, which is supplied to the display and totalizer for display. and accumulative. In this way, the detection and display of traffic is realized.
