GV Air Flow Sensor for VAV Systems Technical Specifications

This document describes a GV air flow sensor designed for direct in-duct installation in VAV boxes, measuring air velocity across the duct cross-section to provide a high-accuracy mean value signal to VAV controllers. It includes technical specifications, materials (ABS plastic bracket, aluminium tube), duct diameter part numbers (63-400 mm), mounting dimensions, and a diagram showing the relationship between air flow and output signal YB for TAC 224V and TAC 224VL controllers.
