GF92 Installation, Operation and

Troubleshooting Guide

A. To get the best results from the instrument, the sensor should be located 20 pipe diameters downstream from any

flow disturbance (valve, pipe elbow, etc.) and 10 pipe diameters upstream from any disturbance.

The instrument tags show the model number, tag number (if noted on the customer’s order), serial number along
with other important safety information. Compare this information with the appropriate pipe installation drawings
and calibration sheets to verify the instrument is the correct configuration.

Tag Location - Between Conduit Ports
On Local Enclosure

If the instrument is a remote configuration, the serial number on the enclosure tags must match. The recommended tag
number on the local enclosure will have an FT in the tag number. The recommended tag number on the remote enclosure
will have an FE in the tag number. (Tags are specified by the customer, “FE/FT” is a recommended naming convention .)

B. Verify the serial numbers on the enclosure(s), flow element and electronics match. The instrument may not work if the

serial numbers do not match. (The instrument has a remote transmitter enclosure (FT) and a local flow element
enclosure (FE).)

C. Recommended installation/troubleshooting tools are an open-ended wrench to fit the NPT connection, an open-

ended wrench to fit the flanged fitting nuts and bolts, a small flat blade screw driver for manipulating potentiometers,
both a medium flat blade screwdriver and a medium phillips head screwdriver for tightening connections, 3 mm allen
wrench for CENELEC approved instruments, a measuring tape for proper flow element placement, and a DVM for
Ohm/Voltage measurements.

Step 2. Flow Element Installation

Alert: DO NOT change the orientation of the flow element in the enclosure as the interconnecting RTD and

heater wiring could be stressed and damaged. DO NOT apply any torque to the flow element
enclosure - only apply to the pipe surface itself.

Install the flow element, with the flow arrow (shown on Page 1) in the direction of media flow. The remote enclosure,
local enclosure, flow element and electronic transmitter serial numbers must all match.

For flange mount flow elements, attach the process mating flange with care. The correct orientation of the flow
element must be maintained to ensure the calibrated accuracy.

• Verify that the process media flow is in the same direction as the arrow on the flat machined area.

• Apply the appropriate gasket and/or sealant to flange mount as required.

• Mate flow element flange to process mount keeping flat oriented properly.

• Attach with bolt, two flat washers, lock washer and nut for each bolt hole, apply lubricant/sealant to male threads
and torque. Refer to ANISI B16.5 specifications.

For NPT pipe thread installations, apply sealant to the male threads. Carefully place in the process media line with the
machined flat facing up. Tighten the process connections. To avoid leaks do not overtighten or cross-thread
connections.

Shown below is the NPT mounting option. Other options are flange mount and butt weld mount. See the Installation
Section in the GF Series Manual, Document Number 06EN003229 for more details.

Step 3. Wiring Preparation

Before the instrument is opened to install the wiring, FCI recommends that the following ESD precautions be observed:

Use a wrist band or heel strap with a 1 megohm resistor connected to ground. If the instrument is in a shop setting there should
be static conductive mats on the work table and floor with a 1 megohm resistor connected to ground. Connect the instrument to
ground. Apply antistatic agents such as Static Free made by Chemtronics (or equivalent) to hand tools to be used on the
instrument. Keep high static producing items away from the instrument such as non-ESD approved plastic, tape and packing
foam.

The above precautions are minimum requirements to be used. The complete use of ESD precautions can be found in the U.S.
Department of Defense Handbook 263.

Open the instrument enclosure to expose the terminal strips. The orientation of the connectors are shown below:

Step 4. Wiring the Instrument

Caution:

Only qualified personnel are to wire or test this instrument.
The operator assumes all responsibilities for safe practices
while wiring or troubleshooting.

Wiring the Instrument into the Customer Application:

This section describes wiring to the transmitter inputs, outputs and interconnection cabling for the remote enclosure. For best
results route the output wiring through the opposite port from the power wiring. See the table on the next page to determine
the size of wiring to be used versus the length of the wire.

Alert:

The instrument contains electrostatic discharge (ESD)
sensitive devices. Use standard ESD precautions when
handling the flow transmitter.
