The standard orifice plate complies with international standards ISO5167 or GB/T362493, and is a structurally simple, widely used, and adaptable type of throttling device.

　　Product features:

1. The institution is simple. Reliable work and stable performance.

2. No calibration is required for flow measurement of large-diameter pipelines, saving calibration fees.

3. Moderate accuracy, suitable for flow control and regulation in process flow.

4. The range that can ensure accuracy is generally 3-4, which is not suitable for situations where the measurement range is too large.

　　Technical parameters:

1. Pressure tapping method: corner joint (ring chamber, separate drilling) for pressure tapping; Flange pressure tapping (preferred)

2. Nominal pressure: ≤ 32Mpa

3. Nominal meridian: 502600mm

4. Reynolds number range: ReD ≥ 5000
