The Aerofólio is a flow meter designed for rectangular: Ducts

Product Summary

The Aerofólio is a differential pressure flow measurement instrument known for its aerodynamic design, resulting in minimal residual pressure loss in the process line.

Main Features:

  • Combustion Control: Ideal for applications in combustion control loops.
  • Repetitive Airflow Signal: Generates a reliable and repetitive airflow signal.
  • Low Residual Pressure Loss: Contributes to efficient system operation.
  • Low Requirement for Straight Run: Requires minimal straight run, saving installation space.

Operation: : The Aerofólio allows air to enter through its rectangular opening and flow through the wings of the instrument. This flow generates a pressure differential measured at the leading edge and the plane of the smallest passage section.

Main Applications:
  • Mining and Basic Industry
  • Petrochemical Industry
  • Oil, Gas, and Refineries
  • Chemical and Process Industries
  • Pulp and Paper Industry
