XGLG throttling device - orifice flowmeter：

The standard orifice plate is a product with a simple structure, easy installation, and the strongest adaptability in throttling devices. Its design, manufacturing, and use comply with the provisions of international standards ISO5167 or GB/T2624.

Main features of standard orifice flowmeter：
The structure is simple, sturdy, and easy to install.
◆ It can measure the flow rate of various gases, vapors, and liquids, with a wide range of applications.

◆ No need for real flow calibration, moderate accuracy.
The attachments are complete and can be used to design calculations for users.
◆ It can be equipped with intelligent differential pressure transmitters to achieve temperature and pressure compensation or fieldbus communication.

Main technical parameters of standard orifice flowmeter：
Pressure measurement methods: corner joint (ring chamber or separate drilling) pressure measurement, flange pressure measurement, radial distance pressure measurement.
◆ Nominal pressure: ≤ 42MPa (when ≥ 20MPa, use high-pressure lens orifice plate or fully welded type)
◆ nominal diameter: 50-2000mm (standard orifice plate) or ＜ 15mm (integral orifice plate); >2000mm (flat hole plate)

Accuracy (uncertainty): ± 1%
◆ Scope of application:

Opening diameter d (mm): d ≥ 12.5 (standard orifice plate)
Opening diameter ratio β: 0.1 ≤ β ≤ 0.75
Reynolds number range ReD: 0.1 ≤ β ≤ 0.75
107 ≥ ReD ≥ 5000 and ReD ≥ 170 β 2D; D is expressed in mm
