Overview-Orifice palte Flowmeter

Orifice plate design based on ISO5167 standards

  • Accuracy, repeatability, and reliability of the flow element
  • Use for custody transfer metering
  • Easy and quick installation and commissioning
  • Very long lifetime product
  • Cost-effective and maintenance-free system
  • Different types of orifice plates are available depending on the application

Orifice plate flowmeter Principle

The liquid or gas whose flow rate is to be determined is passed through the orifice plate.
This creates a pressure drop across the orifice plate which varies with the flow rate, resulting in differential pressure between the outlet and inlet segments.
This pressure drop is measured and is used to calculate the flow rate of the fluid or gas.



Mass & Volumetric flow monitoring of most conductive liquids, gas, and steam.

  • Offer very little pressure drop from which 60% to 65% is recovered.
  • The orifice meter can be easily maintained.
  • Measures a wide range of flows.
  • They have a simple construction.
  • They have easily fitted between the flanges.
  • They are the most suitable for most gases and liquids.
  • They are cheap, The price does not increase dramatically with size.
