The OPTIMA S-FM is a compact airflow measurement device that is designed to provide a continuous reading of the airflow volume in rectangular-shaped ventilation ducts. The airflow measured is interpreted and then transmitted by the analogue signal or by the bus line: Modbus or BACnet. It provides highly accurate measurements to ensure the optimum performance of your ventilation system.

OPTIMA S-FM has a galvanised steel rectangular-shaped casing with flanges for connection with the rectangular duct. Inside the device is equipped with an airflow measurement probe of dynamic ΔP type. The device requires no maintenance once it has been correctly installed making it an adaptable solution for a range of different settings. Other sizes are available in this range.
