Product features
High linearity and good repeatability: the characteristics of symmetrical porous structure, can balance the flow field, reduce the vortex, vibration and signal noise, the stability of the flow field is greatly improved, so that the linearity than the plate increased by 5 to 10 times, repeatability increased by 54%, 0.15%.
The requirements of the straight pipe segment are low: due to the stable flow field, and the pressure recovery is twice as fast as the hole plate, the requirements for the straight pipe segment are greatly shortened, and the front and rear straight pipe segments are generally 1D after the front 3D, the minimum can be less than 0.5D.
Reduction of permanent pressure loss: A balanced design with porous symmetry reduces the formation of turbulence shear and vortex, reduces the loss of kinetic energy, and reduces the permanent pressure loss by 2.5 times compared to the plate under the same measurement conditions.
Anti-dirt is not easy to block: porous symmetrical balance design, reduce the formation of turbulence shear and vortex, thereby greatly reducing the formation of the dead zone, to ensure that the dirty media smoothly through multiple holes, reducing the chance of fluid holes blocked.
Direct replacement of the hole plate: the balance flow sensor and the hole plate have the same use method and shape, so can be replaced directly, do not require any piping changes and related instrument changes, suitable for the whole plant energy metering transformation of the hole plate to balance flow meter.
Long-term stability is good: due to the obvious reduction of the turbulence shear force, the direct friction between the medium and the throttle, its beta value remains unchanged for a long time, the whole instrument is immobile parts, so it can be stable for a long time.
Measureable high temperature and high pressure medium: like the throttle device such as the plate, the operating temperature pressure depends on the material and grade of the pipe and flange, the operating temperature can reach 850 degrees C, the operating pressure can reach 42MPa.
The complex condition medium can be measured: Due to its special structural design, which makes it have special properties, it can be measured in two phases of gas and liquid, mud, and even solid particles. Balanced flow measures bidirectional flow.
