Standard Stainless Steel Orifice Plate Flow Meter For Measuring Gases / Liquids / Vapors

Applicable to the measurement of various gases, liquids and steam, the standard orifice plate flowmeter is one of the most classic and widely used differential pressure flow measurement instruments.

• Simple and robust structure: No moving parts, relatively low cost.
• High degree of standardization: No need for in-stream calibration, supported by international standards, and good interchangeability.
• Long history of application: Most thoroughly researched, complete data, rich experience in design, manufacturing and use.
• Wide adaptability: Applicable to various gases, liquids and steam (with the correct differential pressure transmitter and material).
• Wide range of sizes: Pipe diameters from DN50 to over DN1000 are available.

• Steam trade settlement and energy metering (very common)
• Measurement of gases such as natural gas, coal gas, and compressed air
• Measurement of feedwater and condensate flow in power plants
• Process control and measurement of various clean, single-phase fluids in the petroleum and chemical industries

The standard orifice plate flowmeter, with its simplicity, reliability, standardization and economy, still holds a core position in industrial flow measurement. However, its disadvantages of high pressure loss and narrow range ratio have led to its gradual replacement by conical flowmeters, elbow flowmeters or new types of flowmeters in some applications in today's context of rising energy costs and more flexible process requirements. Nevertheless, in mature standard fields such as steam and natural gas, it remains one of the preferred solutions.
