The FGG FLOWGRIDS are manufactured as a standard galvanised duct frame with multiple Aluminium Flowprobes positioned internally. The total velocity pressure is captured by the FGG Flowgrid and when used in conjunction with the P-Sensor or any CMR Transmitter, it provides a stabile and accurate airvolume measurement which can be used for critical variable or constant air volume control, monitoring and alarming. The ouput signal of the P-Sensor is completely scaled and smooth ready to be connected to any BMS or Scada system..The FGG Flowgrids are ideal for retrofit or new installations. They are made to measure and the packing can contain the Site Tag numbers for easy installation identification.
