The following is a detailed introduction for you:Intuitive and convenient measurement:Using pointers or dials for display, flow data can be directly read without complex conversion, simple operation, and easy on-site observation.Range width ratio:It can maintain stable measurement over a large flow range, and the same flowmeter can meet the measurement needs of different flow rates under various working conditions, with strong applicability.Low pressure loss:The internal structure design is reasonable, and the resistance generated when the fluid passes through is small, which will not excessively affect the pressure of the fluid in the pipeline, ensuring the stable operation of the system.Easy installation and maintenance:Supports multiple installation methods and does not have strict requirements for the installation environment; And with a compact structure, the daily maintenance workload is small, reducing maintenance costs and manpower investment.Diverse materials and corrosion resistance:The shell and internal components can be made of various metal materials, such as stainless steel, Hastelloy, etc., which can adapt to the measurement of corrosive media and expand the application scenarios.Fast response speed:Sensitive to changes in traffic, able to track traffic fluctuations in a timely and accurate manner, and monitor traffic data in real-time.Can achieve remote transmission:In addition to on-site display, accessories such as transmitters can also be equipped to convert flow signals into standard electrical signals for remote transmission and control.
