Balanced flowmeter is the third generation of differential pressure flow meter,it is a kind of multi-holes orifice plate flow meter, the measurement accuracy of this flowmeter is 5~10 times that of traditional DP flow meter, the flow noise is reduced to 1/15, and the permanent pressure loss is about 1/3, the minimum straight pipe section can be as short as 0.5D, there are no moving parts, the installation and use are very convenient and simple, the large straight pipe section can be omitted, the energy consumption required for fluid operation is greatly reduced, and the flow is balanced. It is an energy-saving flow measuring instrument with broad application prospects.

What is the difference between a balanced flow meter and an orifice flow meter?

Higher linearity and better repeatability than traditional DP flow meter
The balanced flow sensor has the characteristics of symmetric porous structure, which can balance the flow field, reduce the eddy current, vibration and signal noise, greatly improve the stability of the flow field, and improve the linearity by 5 to 10 times than the traditional orifice plate, and the repeatability is improved by 54%, which is 0.15%
The straight pipe section is shorter than the orifice flowmeter
The balanced flow sensor is stable due to the stable flow field and the pressure recovery is twice as fast as the orifice plate. The requirements for the straight pipe section are generally 3D upstream and 1D downstream and the small pipe length can be less than 0.5D which saves a lot installation space.
Pressure loss is reduced
The porous symmetrical balance design reduces the formation of turbulent shear forces and eddy currents and reduces the loss of kinetic energy. Under the same measurement conditions, the pressure loss are reduced by 2.5 times compared with the orifice plate, thus it is an energy-saving flow measuring instrument that deserves a lot of promotion.
Dirty fluid is not easy to block
The porous symmetrical balance design reduces the formation of turbulent shear forces and eddy currents, thereby greatly reducing the formation of dead zones and ensuring that dirty media passes through multiple holes, reducing the chance of fluid holes being blocked.
Balanced flow meter can directly replace the orifice flowmeter
It has the same usage and shape as the orifice plate, so orifice plate can be directly replaced by balanced flow meter, without any piping changes and related instrument changes; it is suitable for the whole plant energy metering EMS transformation to change the orifice plate to the balance flowmeter.
