Functional description
RFD-SIRIUS combines the functions of a volume flow controller, sound attenuator, plenum box and air terminal device in one unit. To determine the current actual volume flow rate, the differential pressure is measured using the integrated measuring tubes and transmitted to the controller. Depending on the desired setpoint value, the volume flow control unit is adjusted with an integrated linear actuator. The construction of the diffuser ensures that sound is effectively absorbed, which results in low sound power levels.
Application
Installation and commissioning
Upstream conditions
The volume flow rate accuracy ΔV applies to a straight upstream section of the duct. Bends, junctions or a narrowing or widening of the duct cause turbulence that may affect measurement. Duct connections, e.g. branches off the main duct, must comply with EN 1505. Some installation situations require straight duct sections upstream.
