Concentric orifice plates are among the most widely used flow measurement devices in
industrial systems. Known for their accuracy, simplicity, and cost-effectiveness, they play a
crucial role in monitoring and controlling fluid flow.
At Arrotop, we provide precision-engineered concentric orifice plates designed for reliable
performance in critical industrial applications.
What is a Concentric Orifice Plate?
A concentric orifice plate is a flat metal plate with a centrally positioned circular hole, installed
between pipeline flanges. It works on the principle of differential pressure, where the flow
restriction creates a pressure drop used to measure flow rate.
This type is the most common orifice plate design, widely preferred for its accuracy and
standardized performance.
Key Features
Concentric orifice plates are widely used due to their:
- High accuracy in flow measurement
- Simple and robust design
- Easy installation and maintenance
- Cost-effective solution for industrial systems
- Compatibility with standard flow measurement systems
They are particularly suitable for clean, single-phase fluids such as liquids, gases, and steam.
