     Our assemblies are engineered for stable performance even under fluctuating operating conditions.
Working Principle - Orifice Plate Flange Assembly
     The Orifice Plate Flange Assembly operates on the differential pressure measurement principle based on Bernoulli’s theorem.
When fluid flows through the pipeline and passes through the orifice plate restriction:
- Fluid velocity increases
- Pressure decreases across the orifice
- Differential pressure is generated
- Pressure taps installed on the flanges measure the pressure difference
- The flow rate is calculated using the differential pressure value
This method is one of the most economical and widely accepted techniques for industrial flow measurement. It provides accurate flow monitoring for liquids, gases, and steam applications across various industries. The assembly ensures stable performance, repeatable measurement accuracy, and reliable operation even under high-pressure and high-temperature operating conditions.
