Aerofoil

The Aerofoil is a solution specifically designed for differential pressure flow measurement in rectangular ducts. Due to its wing-shaped aerodynamic design, the Aerofoil provides a smooth passage for the fluid, resulting in minimal residual pressure loss.

Key Features:

Reduced Straight Length: Requires a short upstream and downstream length for installation.
Low Permanent Pressure Loss: Ensures minimal pressure drop during operation.
Low Maintenance: Has no moving parts, eliminating the need for frequent maintenance.
Size Versatility: Available for ducts of 500mm and larger, with the possibility of smaller sizes upon request.
Repetitive Airflow Signal: Generates a reliable and repetitive airflow signal.

Main Applications:

Pulp and Paper Industries
Sugar and Ethanol Plants
Chemical and Petrochemical Plants
