Orifice Plates

Product Summary

The Orifice Plate is a type of Depressurization flow meter, designed to generate a pressure differential in the flow, allowing precise flow measurement. These plates are widely used in various industrial applications to monitor and control the flow of liquids and gases.

Main Features:

  • Easy Installation: Orifice Plates are easy to install, making integration into existing systems simple and efficient.
  • Low Cost: They are an economical option for precise flow measurements, ideal for optimizing project budgets.
  • High Accuracy: They offer high precision in flow measurement, ensuring reliable results.

Operation: Orifice Plates consist of metal plates with accurately sized holes. These plates are installed perpendicular to the axis of the pipeline, resulting in a change in the fluid flow profile, causing a variation in pressure. This pressure variation is then measured and converted into flow. This operating principle is based on the continuity and Bernoulli's equations.

Main Applications:

  • Water Treatment and Sanitation
  • Oil and Gas Industry
  • Petroleum Refineries
  • Chemical and Pharmaceutical Industry
  • Food and Beverage Industry
  • Mining and Energy Sector
  • Paper and Pulp Industry
  • Steel Industry
