FP7002/FP7002A Flow/Temperature Transmitter

The FP7002 has magnets installed in the rotating paddles; these
magnets will tend to attract rust from the flowing fluid. Thus, it is
NOT recommended to install the FP7002 in pipes which under typical
conditions contain rust, such as in cast iron, black iron, carbon steel
and other iron pipes (galvanized pipe has been treated to resist rust). In
situations where rust can not be avoided, it is recommended to install a
fine magnetic filter at least 50 pipe diameters upstream from the FP7002
and to periodically shut down the line and remove the sensor from the
installation fitting for cleaning.
2.4 Electrical Connections
CAUTION
All electrical connections and wiring should be performed
by suitably trained personnel only.
N O T E
To insure proper hook-up to your indicating device, the
paddles of the FP7002 can be spun in the open air by
blowing onto them before the sensor is installed into the
installation fitting.
This is particularly important where the pipeline can not
be conveniently shut down and the sensor removed after
installation.
