Eco Rectangular Flowgrid

The Eco Rectangular Flowgrids has been developed to offer a low-cost alternative to our existing range of stainless steel Wilson Flow Grids and front end devices. The enhanced, lightweight aluminium design has reduced lead times and air blockage, making it ideal for HVAC and other industries.

The Eco Rectangular Flowgrids has been developed to offer a low-cost alternative to our existing range of stainless steel Wilson Flowgrids and front end devices. The Eco Rectangular Flowgrid is a fully Aluminium and is comprised of either three or five, equally spaced, pressure tubes, that span the whole duct area. Each tube projects from an aluminium mounting plate with integrated manifold and has logarithmically spaced pressure sensing holes for maximum accuracy. One set of holes face upstream and the other set downstream.

The signal generated is an average signal for both the total and sub-static pressures. These signals in turn generate an enhanced “magnified” differential pressure signal that directly relates to the air volume flow within the duct.

Eco Radial Flowgrid are arranged in a similar way, only each tube protrudes from a centre boss, in which the signals are averaged.
