GIC is the leading Aerofoil Manufacturer in India providing reliable solutions for accurate pressure measurement to process industry worldwide.

Aerofoil is primary flow element use to measure air flow in rectangular duct. An aerofoil is having the shape of the cross section of the aircraft wing, with the function of producing a controllable net aerodynamic force.

Aerofoil works on the principle of the relationship between flow velocity and the pressure fields in frictionless flow. Since the air particles follow the curved streamlines above the upper surface there must be a centripetal force across the streamlines which is accelerating the flow towards the centre of curvature. That force must be associated with a pressure gradient across the streamlines i.e. ambient atmospheric pressure at some distance from the surface grading to a lower pressure on the upper wing surface.
