|---|---|
Nominal diameter | 10mm≤DN≤3000 mm |
Accuracy class | ±0.5%、±1.0% |
Aepeatability | ≤0.1% |
Range ratio | 1：10 OR 1:15 |
Medium operating pressure | ≤25MPa |
Permanent pressure loss (Pa) | ≤0.31ρV2(ρ density kg/m 3 V average flow rate m/s) |
Features:
1. High measurement accuracy. As the porous balanced flow sensor is actually a flow rectifier, it can effectively eliminate vortices and improve velocity distribution distortion, making the flow field approximate to the ideal state, and the measurement accuracy is 0.5 or 1.0 level.
2. Wide range ratio, because large diameter and small flow measurement is the problem of most flow sensors, and porous balance flow sensor is porous structure, choose the appropriate equivalent diameter ratio, can be weighted to the main measurement of the lower limit flow and take into account the upper limit flow, so that the conventional measurement of flow range ratio of 1:10, extended range can be 1:15.
3. Straight pipe section requirements are low, a certain length of straight pipe section is mainly used to make the fluid flow in which tends to be stable, and porous balance flow sensor itself is a flow regulator, so it can almost be directly connected to the valve, tee, elbow and other choke parts, does not affect the flow measurement.
4. Low permanent pressure loss,The flow sensor installed in the pipeline will inevitably produce pressure loss due to its flow resistance, and the porous structure of the porous balance flow sensor can disperse resistance, effectively reduce the formation of eddy current and turbulent friction, reduce permanent pressure loss, so as to achieve energy saving effect.
