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.
X – UX 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.
The MX model has a Magnification Factor >1.8
The UX model has a Magnification Factor of ~1
