2.2 Operating Principle-Figure 2 The working principle of the LGP balanced flow meter is the same as that of the orifice plate. It is also based on the energy conservation law of Bernoulli equation. When the fluid passes through the function hole of the disc, the fluid will be balanced and adjusted, the vortex will be minimized, and an ideal flow field will be formed. -

When the impurity content in the fluid is high, the standard flow element is easy to be inaccurate due to solid deposits and wear on sharp edges, and the porous LGP balanced flow meter can eliminate the deposition of circular objects due to its porous characteristics; because of its balance (without sharp edge) can solve the phenomenon of sharp edge wear. -
