Orifice type / Differential Pressure Flowmeter

For low Flow applications, we offer specially designed Orifice Flow Metering Systems.

The Orifice Flow Meter is known for its stable long-term accuracy and repeatability. With the use of Orifice Flow Meter, there is a reduced possibility of process fluid leakage. Also, this Orifice Flow Meter has a lower cost of installation than traditional orifice-type meters. To add to that, this highly efficient Orifice Flow Meter requires no special protection against extreme weather conditions.

From low cost Volumetric measurement to specialized applications requiring on-line density correction, we offer complete integrated ready to use Orifice Flow Measurement systems.

Orifice type / Differential Pressure Flowmeter

The orifice is designed for customer specific application , and integrated with the best of components from our own manufacturing range to provide you with the most accurate and predictable flow measurement solution.

It operated on the principle that, when flowing fluid flow through obstruction placed in direction of flow, it create pressure drop called Δ P.
This Δ P is proportion to square root of flow flowing liquid/steam/gas inside the pipe.

Orifice plate base flow meter consist of :-

  • Integral orifice plate
  • Differntial Pressure Transmitter
  • Pressure Transmitter
  • Temp. Sensor
  • Measurement precision 0.3, Tenfold of Orifice Plate
  • Requirement of straight pipe less than 0.5D
  • Pressure loss is 1/3 of orifice plate,
  • pressure recovering double faster than orifice plate
  • Flowing noise proportion orifice plate1:15
  • Replace orifice plate to save cost directly
  • Complex working conditions could be measured
  • Balanced and stable, energy saving and environmental
