X and UX Flowgrids

X - UX Grids


X-Grids consist of two tubes mounted diagonally through the cross section of a duct and are easy to install and maintain. The holes in the first tube face upstream (Total Pressure), whilst those in the second tube face downstream (Sub-Static Pressure). The holes in the second tube of the UX-Grids also face forward but at an included angle. In both cases these tubes generate an averaged signal to generate a differential pressure signal that directly relates to volume flow. Standard Performance Data is available.
