Small Diameter Meters: Integral Orifice

Product Summary

The Integral Orifice is a complete flow measurement solution designed for diameters smaller than those specified in traditional orifice plate standards. This instrument operates based on the principle of flow measurement by pressure differential, providing a precise and cost-effective alternative for measuring flow in smaller pipes. The instrument utilizes a centrally mounted orifice plate within the pipe in accordance with applicable standards to prevent installation errors.

Main Features:

  • High Accuracy in Measurement: Provides highly accurate flow measurements, ensuring reliable results.
  • Complete Solution: Piping with centrally mounted Orifice Plate ensures measurement precision and eliminates installation errors.
  • Easy Installation: Its simple installation makes the Integral Orifice a convenient choice for various applications. The instrument is provided complete.

Operation: The Integral Orifice incorporates a centrally mounted orifice plate, ensuring that the device is correctly positioned in the piping, eliminating the need for complex adjustments. The orifice plate induces a pressure variation by altering the fluid's flow profile, and this variation is measured and converted into the process flow. The operating principle is based on the continuity and Bernoulli's equations.

Main Applications:
  • Water and Sanitation Treatment
  • Oil and Gas Industry
  • Petroleum Refineries
  • Chemical and Pharmaceutical Industry
  • Food and Beverage Industry
  • Mining and Energy Sector
