LGP balanced flow meter is a flow element developed on the basis of standard orifice plate. Its sensor is a porous disk throttling rectifier mounted on the section of the pipe. Size and distribution of each hole are customized based on test data and become function holes. The balanced flow meter sensor can realize the fluid balance measurement skillfully, obviously reduces the eddy current formation, reduces the dead effect and the fluid kinetic energy loss.

The LGP balanced flow meter is a throttle device researched based on the standard orifice. Its sensor is a round plate throttle rectifier with many holes installed on the cross-section of the tube. The size of the holes and their location is produced according to test data and is named as function holes. The sensor of the balance flow meter can realize flow balance measurement. Obviously, it can decrease the eddy current, reduce the dead zone effect, decrease the flows kinetic energy loss, and reduce the signal volatility of the tapping position which is caused by the eddy current. With the features of high precision, short straight pipe needed, little drop pressure, the balanced flow meter is widely used in gas, chemical, refinery industries etc.
Operating Principle
LGP balance flow meter working principle is same as orifice, and basing on Bernoulli equation of the law of conservation of energy, when the flow passes through the function hole on the round plate, the flow will be balance adjusted, the eddy current will be minimized, performing the ideal flow, and gained the stable different pressure signal by tapping device.
In the formula, α is the flow coefficient. It can be seen from the above relationship that if the orifice area and fluid density are constant, the flow rate is proportional to the square root of the pressure difference, that is, as long as the pressure difference is measured, the flow rate can be calculated. The flow element measures the fluid flow rate based on this principle.
Features
1.High accuracy
2.Low requirement of straight pipe section, in most cases the straight pipe section can be as small as 0.5 D~2 D, a large number of straight pipe sections can be saved by using LGP balanced flow meter;
3.Low permanent pressure loss and the differential pressure value is not reduced under the same measuring condition, the permanent pressure loss can be reduced by ½ ⅓.
4.Wide range ratio
5.Good repeatability and long-term stability
6.Wide range of application, can measure the gas-liquid two-phase, slurry and even solid particle. The balanced flow meter measures the complete symmetry of the left and right of flow element, so the bidirectional flow can be measured.
Applications
Refining: Hydrocracking, isomerization, catalytic reforming, sulfur recovery
