Ransburg RF1 FiberOptic Meter 77786-XX, A11516-XX - Manual (Page 16)

FM-00-02.5
The transmitter functions by detecting changes in
very weak magnetic fields caused by the rotation
of the gears within the flow meter. Unfortunately it
will also respond to stray magnetic fields if they
are present. Stray fields can be caused by nearby
transformers, relays, solenoids, or AC line
energized wiring. For proper operation the
transmitter must be located away from these
stray fields.

The fiber optic transmitter / flow meter is designed
to be intrinsically safe and may be mounted in a
hazardous (classified) location which may contain
a potentially explosive atmosphere. The transmitter
is intrinsically safe as long as it is installed in
accordance with the hazardous area classification
defined in the “Specification” section in the
“Introduction” section of this manual.

exposes it to stray magnetic fields will result in
improper operation. The meter body must also
be grounded to true earth ground for proper
operation.

The fiber optic receiver is not designed to be
intrinsically safe and must not be mounted in a
hazardous (classified) location. If you are unsure
about what constitutes a hazardous area please
refer to your local electrical codes.

Pick a suitable location as outlined above. Keep in
mind the physical fluid connections and the fiber
optic cable connection. The meter / transmitter
combination is designed for fluid flow in one primary
direction. The fluid inlet to the high pressure meter
is located below the fiber cable connector and on
the bottom of the low pressure unit.

> >> > > The low frequency performance of the trans-
mitter is dependent on the spacing between the
pickups and the gears inside the flow meter.
Dirt or debris between the meter and transmit-
ter that increases this distance may result in
poor operation of the meter at low flow levels.
!
> >> > > Running the meter / transmitter in the reverse
direction will cause no operational problems
but will result in a significant decrease in the life
of the transmitter battery and hence the trans-
mitter.
