The multi-hole balanced flow meter is a new type of differential pressure flow instrument. Its multi-function hole design can quickly adjust the flow field disturbed by the throttling device, reduce vibration and signal noise, improve repeatability and stability, and further enhance measurement accuracy. It is now widely applied in fluid measurement across various industries.
1. Multi-Hole Balanced Flow Meter vs Traditional Orifice Plate Flow Meter
Traditional Orifice Plate Flow Meter
It consists of a circular plate with a single central hole, installed in the center of the pipeline. With only one throttling hole, it easily generates massive eddy currents and dead zone effects, resulting in poor measurement linearity and repeatability.
Multi-Hole Balanced Flow Meter
It is composed of a pipeline and a flow meter. The flow meter is equipped with a multi-hole disc throttling rectifier (balanced flow sensor) installed on the pipeline section. The size and distribution of each hole are customized based on professional formulas and test data, known as functional holes.
The symmetrical distribution of multiple holes basically eliminates the dead zone effect caused by single-hole throttling and greatly reduces eddy currents in the pressure tapping area, achieving much higher measurement accuracy.
2. Measurement Advantages of HSP Multi-Hole Balanced Flow Meter
-
High Linearity & Excellent RepeatabilityThe multi-hole structure rectifies fluid and suppresses eddy currents, improving linearity with repeatability up to 0.15%.
-
Low Straight Pipe RequirementBenefiting from stable flow field, it greatly reduces the demand for straight pipe sections, only requiring 3D upstream and 1D downstream.
-
Low Permanent Pressure LossThe balanced multi-hole design reduces kinetic energy loss, with permanent pressure loss 2.5 times lower than traditional orifice plates.
-
Fouling Resistance & Anti-CloggingIt restrains the formation of turbulence and eddy currents, effectively lowering the risk of hole blockage.
-
Wide Flow Measurement RangeBeta value ranges from 0.25 to 0.90, with an effective turndown ratio of over 1:10 under ideal working conditions.
-
Long-Term StabilityThe throttling part adopts increased thickness and no chamfer design, keeping the beta value unchanged permanently and ensuring long-term stable operation.
-
High Temperature & High Pressure ResistanceCustomized according to pipeline materials, it can withstand working temperature up to 550℃ and working pressure up to 42MPa.
-
Suitable for Complex Working ConditionsIt is applicable to mixed gas, steam, multi-phase water flow, vibrating water flow, electromagnetic interference medium and bidirectional flow measurement.
-
Safe & Reliable OperationIntegrated automatic welding is adopted with non-destructive testing for all welding positions to ensure safe and stable operation.
-
Diversified Connection MethodsFlange connection, wafer connection and direct welding type are optional to adapt to various on-site working conditions.
In addition, for energy metering upgrading and renovation projects, the HSP multi-hole balanced flow meter can directly replace traditional orifice plates, helping enterprises save renovation and replacement costs greatly.
