What is the principle and function of ultrasonic flowmeter? When ultrasound propagates in a flowing fluid, it carries information about the fluid velocity. Therefore, by receiving the ultrasound signal, we can detect the fluid velocity and further convert it into flow rate. According to different detection methods, ultrasonic flow meters can be divided into types such as propagation velocity difference method, Doppler method, beam offset method, noise method, and correlation method. Ultrasonic flowmeter is a non-contact instrument suitable for measuring fluids that are difficult to contact and observe, as well as large pipe flow rates. It can be linked with a water level gauge to measure the flow of open water. Since it does not change the flow state of the fluid and does not generate additional resistance, the installation and maintenance of ultrasonic flow meters do not affect the operation of production pipelines, making it an ideal energy-saving flow meter. Ultrasonic flow meters have significant advantages in measuring large pipe diameters and large flow rates. The common problem with current industrial flow measurement is that with the increase of measuring pipe diameter, general flow meters will bring difficulties in manufacturing and transportation, such as increased cost, increased energy loss, and cumbersome installation. However, ultrasonic flow meters can avoid these problems. The cost of ultrasonic flow meters is basically independent of the size of the measured pipeline diameter, while other types of flow meters will have a significant increase in cost as the diameter increases. Therefore, the larger the diameter, the better the functional price ratio of ultrasonic flow meters compared to other types of flow meters with the same function. The Doppler method ultrasonic flowmeter can measure the flow rate of two-phase media, making it suitable for measuring dirty flows such as sewers and sewage. In power plants, using portable ultrasonic flow meters to measure large pipe flow rates such as water turbine inlet and turbine circulating water volume is much more convenient than traditional pitot tube flow meters. Ultrasonic flow meters are also suitable for gas measurement. The applicable range of pipe diameter is from 2cm to 5m, and it can be used for channels ranging from several meters wide open channels and culverts to 500m wide rivers. The accuracy of flow measurement of ultrasonic flowmeter is almost unaffected by parameters such as temperature, pressure, viscosity, density, etc. of the measured fluid. It can be made into non-contact and portable measuring instruments to solve the flow measurement problems of strong corrosive, non-conductive, radioactive, and flammable and explosive media that are difficult to measure with other types of differential instruments. Ultrasonic flow meters have non-contact measurement characteristics, and one instrument can adapt to measuring multiple pipe diameters and flow ranges with multiple resistant chains. The adaptability of ultrasonic flow meters is incomparable to other instruments. Ultrasonic flow meters have some of the advantages mentioned above, so they are increasingly being valued and developing towards product series and universality. At present, ultrasonic flow meters have been made into standard, high-temperature, explosion-proof, and wet type instruments with different channels to adapt to flow measurement in different media, occasions, and pipeline conditions.
