Duct Flowprobes

The MDF Duct Flowprobes are ideal to measure air volumes in round spiral ducts from 80 up to 500mm diameter (maximum 710mm with support bracket). The MDF produce an average differential velocity pressure to provide an air volume measurement for fan proving, VAV or CAV volume control in ducts and general ventilation applications. They are made of Aluminium and can be mounted easily by simply drilling a 25.4 mm round hole into the duct.

The RDF Flowprobes are ideal to measure air volumes in round,oval, rectangular and square ducts. They produce a stabile air volume signal ready to be used in any constant or variable air volume control, monitoring or alarming appliaction by BMS or Scada system intergrators when used in conjunction with the P-Sensors or any CMR Transmitters. They are made of Aluminium and can be mounted easily by simply drilling a 25.4 mm round holes into the duct.

The OAF Attenuator Flowprobe incorporates the CMR Alumimium Flow Probe and has a bottom and top bracket with expansion springs, so that the probe can be pushed into the attenuator slot and is held in position by the spring power and a couple of self tapping screws. The Flowprobes are used to measure the velocity pressure in the passage way of an attenuator to provide a stabil measurement for control, monitoring and alarming.
