Fan Array AirFlow Totalizing System
FAATS-1000 Fan Array Airflow Totalizing System
The FAATS-1000 Fan Array Airflow Totalizing System has been specifically designed to provide a cost effective means for accurate (±0.25%F.S.) airflow measurement of up to forty individual fans within a single fan array or forty combined fans in an air handling unit with both supply and return fan arrays. The individual airflow rate of each fan in an array is indicated on a seven inch, full color, Human-Machine-Interface (HMI) touch screen panel as well as the summed (total) airflow rate of each array. The total airflow rate of each array is also made available to the Building Management System (BMS) via dedicated field selectable 0 to 5 VDC, 0 to 10 VDC, or 4 to 20 mA analog outputs. Individual fan airflow rates and total airflow rates for each array are also available to the BMS via BACnet®-MS/TP Master or Modbus® RTU Slave network communications. Independent monitoring of each fan allows the FAATS-1000 to identify and alarm fan failures and airflow rate discrepancies between fans.
