Multihole Orifice Plate: Digi 5F

Product Summary

The DIGI5F is an advanced Orifice Flowmeter that operates based on the principle of generating a pressure differential in the flow to accurately measure flow rate. This innovative device features a unique configuration, using not just one, but five orifices to condition the flow, resulting in the need for a shorter straight run for installation, providing greater flexibility.

Main Features:

  • Easy Installation: The five-orifice configuration reduces the need for a long straight run before measurement, simplifying installation.
  • Low Cost: Provides an economical option for accurate flow measurements.
  • High Accuracy: Delivers highly accurate flow measurements, ensuring reliable results.

Operation: The DIGI5F is a metal plate that features five precisely sized holes. These holes are installed perpendicular to the pipe axis, altering the fluid flow profile and generating a pressure variation. This pressure variation is then measured and converted into the process flow. The operating principle is based on the continuity and Bernoulli's equations, similar to a traditional orifice plate. However, the difference here is that, in addition to generating the pressure differential, the DIGI5F also conditions the flow, allowing measurement with a shorter straight run.
