Performance characteristics:
1. Although the flow velocity through each point on the pipe cross-sectional wind measuring device is not constant, it is required to be stable. In the occasion where the pipeline installation environment is harsh, a flow regulator is used and placed upstream of the speed measuring device. Its role is to convert an unstable fluid into a bundle of stable fluids within an equal length for accurate measurements.
2. Because the flow velocity through the pipeline cross-section measuring device at each point is not equal, it is required that the value measured by the sensor be as close as possible to the average value. Structurally, the average of the sum of the velocity at each point is generated. The detection probe detects the total pressure and static pressure of the air flow in accordance with the principle of multi-point automatic balance pitoting.
3, no straight pipe before and after, as long as there are 250 ~ 300mm long installation position.
4. It can measure airflow at an angle of 30° without being affected by irregular fluids or even multi-rotating airflow.
5, does not require on-site calibration, that flow coefficient K = 1.
6, the pressure loss is very small.
7. The positive pressure hole and the static pressure hole are in the direction of flow, which greatly reduces the possibility of blockage.
