Air flow regulator EMSF

Tested and calibrated device for accurate Demand Control Ventilation ductwork Functionally tested and calibrated Accurate measuring for an easy and fast commissioning Available in 9 sizes from 100 to 630 mm Galvanised steel All duct fittings are equipped with a sealing ring made of EPDM rubber Integrated orifice plate for air measurement Pneumatic pressure measuring optional Tightness class B EMSF is a measuring device for the Optivent system. It generates an electrical voltage or a pneumatic pressure which represents the actual air flow. EMSF is designed to be used in variable air volume (VAV) systems to create a balance between the supply and extract air in a zone. EMSF measures all the supply air to a zone and sends an output signal to an extract air flow damper (e.g. EMSS). A special offset function can be used to compensate constant air flows and control pressure levels in zones and rooms (GT). The EMSF measuring device is available in nine sizes with circular connection spigots for duct diameters from 100 to 630 mm. All control equipment is installed on the apparatus casing. Manual measurement of the air flow can be performed without disturbing the control circuit via a separate pressure outlet on the orifice plate of the measuring device. All duct connections have spigot dimensions and are equipped with sealing rings made of rubber. EMSF reaches air tightness class B in accordance with EN1751:1998. • Air flow measuring device • Electronic control equipment (analog and Modbus) • Integrated orifice plate measurement • Real time air flow display • Available in nine sizes for duct diameters 100 -630 mm
