Characteristics and working principle of balanced flow meter

1. Characteristics: High linearity and good repeatability: The balanced flow sensor has a symmetrical porous structure, which can balance the flow field, reduce eddy currents, vibrations, and signal noise, and greatly improve the stability of the flow field.

. The linearity has been improved by 5-10 times compared to orifice plates, and the repeatability has been increased to 0.15%, ensuring high measurement accuracy and stability. Low requirements for straight pipe sections: Due to the stable flow field and pressure recovery twice as fast as orifice plates, the requirements for straight pipe sections are greatly reduced. The straight pipe section before and after the balanced flowmeter is generally 3D in front and 1D in back (D is the diameter of the pipeline), and the minimum can be less than 0.5D, thus saving installation space. Low permanent pressure loss: The porous symmetrical balance design reduces turbulent shear forces and vortex formation, reducing kinetic energy loss. Under the same measurement conditions, the permanent pressure loss is reduced by 2.5 times compared to the orifice plate, saving operating energy costs. Resistant to dirt and easy to block: The porous symmetrical balance design reduces the formation of turbulent shear forces and eddies, and reduces the formation of stagnant dead zones. Ensuring the smooth passage of dirty media through multiple holes reduces the chance of fluid hole blockage and improves measurement reliability. Directly replaceable orifice plate: The balanced flow Porous balance flowmeter

meter has the same usage method and appearance as the orifice plate, and can be directly replaced. No changes in piping or related instruments are required, saving costs for upgrading and renovating enterprise instruments. Wide flow measurement range: The performance of a balanced flowmeter allows its flow rate to range from minimum to supersonic. The minimum Reynolds number can be below 200, and the maximum Reynolds number is greater than 107; The B value can be selected from 0.25 to 0.90, which meets the measurement requirements under different working conditions of rock collapse. Long term stability is good: the significant reduction of turbulent shear force reduces the direct friction between the medium and the throttling element. The B value remains unchanged for a long time, and the entire instrument has no movable parts, ensuring long-term stability. Measurable high temperature and high pressure medium: The working temperature can reach 550 ° C, and the working pressure can reach 42MPa. Suitable for flow measurement under high temperature and high pressure conditions. Measurable for complex working conditions: It can measure various mixed gases, gas-liquid two-phase media (such as moisture), slurries, multiphase water flows, vibrating water flows, electromagnetic interference media, rough circles, and bidirectional flows. Suitable for flow measurement under complex working conditions. Safer and more reliable: The instrument is welded using internationally advanced automated welding equipment and undergoes non-destructive testing technology. Operating under special conditions is safer and more reliable, ensuring measurement accuracy and stability.
