3 Product description
3.1 Functional description
The air flow sensor measures and monitors the analogue air speed within a server enclosure, e.g. to
record the contamination level of a filter mat. It reports the measured air speed to the connected
CMC III PU. The air flow sensor has an identification that allows it to be detected automatically by the
CMC III PU.
3.2 Proper use
The CMC III Analogue Air Flow Sensor is used only to measure and monitor the analogue air speed
within a server enclosure. It may be used only together with the CMC III PU. Any other use is not per-
mitted.
