Sensing Precision has launched the Eco Rectangular Flowgrid, a new low-cost aluminium alternative to its existing well-known range of stainless steel Wilson Flow Grids.
Originally designed in 1968 by Connor Wilson, the Wilson Flow Grid is still manufactured by Sensing Precision, the air measurement specialists, at its Buckinghamshire factory. Over the past 55 years, this iconic air flow measurement device has been installed in tens of thousands of buildings throughout the UK, and across the globe.
The new Eco Rectangular Flowgrid is fully aluminium consisting of either three or five logarithmically 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.
Andrew Hamshere, managing director of Sensing Precision, said, “This additional product range provides customers with further options. The aluminium range reduces costs and lead times, while retaining all the performance associated with our Wilson Flow Grid range. It also reduces air blockages.”
The Eco Rectangular Flowgrid is designed to EN ISO 3966:2008. It comes in sizes from 200mm x 100mm to 1,200mm by 800mm.
