Fuji Ultrasonic flowmeter is a non-contact flowmeter that has been applied in recent decades with the rapid development of integrated circuit technology, suitable for measuring fluids that are not easy to contact and observe and large pipe runoff. Together with the water level gauge, it forms an open channel flowmeter that can measure the flow of open water. The use of ultrasonic flowmeter does not need to install measuring elements in the fluid, so it does not change the flow state of the fluid, does not produce additional resistance, and the installation and maintenance of the flowmeter does 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 a large diameter, large flow measurement difficulties, this is because the general flow meter with the increase of the diameter of the measurement pipe will bring manufacturing and transportation difficulties, cost increase, energy loss increase, installation not only these shortcomings, ultrasonic flow meters can be avoided. Because all kinds of ultrasonic flowmeters can be installed outside the tube and non-contact flow measurement, the cost of the flowmeter is basically unrelated to the diameter of the pipeline being measured, and other types of flowmeters increase with the diameter, the cost increases significantly, so the larger the diameter of the ultrasonic flowmeter than other types of flowmeters with the same function, the more superior the functional price ratio. It is considered to be a better large-pipe runoff measuring instrument, and the Doppler ultrasonic flowmeter can measure the flow of two-phase media, so it can be used for the measurement of sewage and sewage and other dirty flows. In the power plant, it is much more convenient to use portable ultrasonic flowmeter to measure the large pipe runoff such as the water intake of turbine and the circulating water of turbine. Ultrasonic flow juice can also be used for gas measurement. The application range of pipe diameters is from 50px to 5m, from open channels and culverts a few meters wide to rivers 500m wide.

In addition, the measurement accuracy of Fuji ultrasonic flowmeter is almost not affected by the temperature, pressure, viscosity, density and other parameters of the measured flow body, and can be made into non-contact and portable measuring instruments, so it can solve the problem of flow measurement of strong corrosive, non-conductive, radioactive and flammable and explosive media that are difficult to measure by other types of instruments. In addition, in view of the non-contact measurement characteristics, coupled with a reasonable electronic circuit, a flowmeter can be adapted to a variety of pipe diameter measurement and a variety of flow range measurement. The adaptability of ultrasonic flowmeter has the advantages that other meters cannot compare. Ultrasonic flowmeter has some of the above advantages, so it is more and more attention and to product serialization, universal development, has been made of different channels of standard type, high temperature type, explosion-proof type, wet type instrument to adapt to different media, different occasions and different pipeline conditions flow measurement.
