5. Installation
Note: I/O wiring should not be in close proximity or in the same conduit as any AC
power, controller/driver or relay wiring.
The enclosure is rated IP 66 (NEMA 4X) and can be mounted indoors or out. The PG
fittings provided must be tightened around any cables to maintain the rating.
Do not expose the electronics to vibration or direct sunlight. If an outdoor installation is
required and intense sunlight is expected, provide a sun shade to reduce ambient
temperature and to make the display easier to read.
The RCM-2000 detector and electronics are matched at the factory and will have the
same serial numbers. When replacing the detector there is a configuration file that can be
downloaded through the front panel RS-232 serial port for simple setup.
Install RCM flow sensor in the process line. The arrow on the sensor tag indicates flow
direction. The detector can be mounted with the electronics or it can be remote mounted.
Mounting position is not critical but if possible ensure that the electrodes are always
wetted even at zero flow conditions.
For vertical pipe runs, the fluid should move upwards. As with any metering device it
should be upstream of any control valves. A good rule of thumb is the detector should
always be mounted on the pressurized system side in a flow control system. This is
mandatory for low flow applications below 250CCM.
