Determining a Location
Step 1 Determining a Location
Choose a location for the sensor based on the requirements described in this section. The following general
guidelines can help you select an appropriate location for the sensor.
• You should be able to stop flow through the sensor to facilitate the zeroing procedure.
• For optimal performance, the sensor should remain full of process fluid.
• The sensor must be installed in an area that is compatible with the classification specified on the
approval tag (see Figures 1–7).
Hazardous area installations
Make sure the hazardous area specified on the sensor approval tag is suitable for the environment in which the
sensor is installed. (See Figures 1–7.) For installation in an area that requires intrinsic safety, refer to the
appropriate Micro Motion approval documentation, shipped with the sensor or available from the Micro
Motion web site at www.micromotion.com.
WARNING
Failure to comply with requirements for intrinsic safety in a hazardous area
could result in an explosion.
• Make sure the hazardous area specified on the sensor approval tag (Figures 1–7)
is suitable for the environment in which the sensor will be installed.
• For installations in an area that requires intrinsic safety, use this document along
with Micro Motion approval documentation, shipped with the sensor or available on
the Micro Motion web site at www.micromotion.com.
• For hazardous installations in Europe, refer to standard EN 60079-14 if national
standards do not apply.

12 Sensor Installation: F-Series
Determining a Location
Environmental limits
The maximum ambient temperature for the sensor depends on the electronics option:
• For F-Series sensors with a junction box or an extended core processor, the maximum ambient
temperature is 140 °F (60 °C).
• For all Model F300A sensors, the maximum ambient temperature is 140 °F (60 °C).
• For F-Series sensors with an integral core processor or Model 1700/2700 transmitter, the maximum
ambient temperature is described by the graph in Figure 8. To determine your maximum ambient
temperature, locate the range within which your maximum process temperature falls on the horizontal
axis of the graph, then find the intersecting maximum ambient temperature on the vertical axis.
Figure 8 Maximum ambient temperature for F-Series sensors with an integral core
processor or Model 1700/2700 transmitter
Hazardous area approvals may impose additional limits on ambient and process temperature. For the
ATEX “T” rating, refer to the ATEX documentation shipped with the sensor or available on the Micro Motion
web site at www.micromotion.com/atex. CSA ambient temperature limits are listed in Table 1.

Determining a Location
Maximum wiring distances
The maximum distance between the sensor and transmitter depends on cable type. See Table 2.
Pipe run
Micro Motion sensors do not require a straight run of pipe upstream or downstream.
Valves
After the sensor and transmitter have been installed, you must perform the zeroing procedure. During the
zeroing procedure, flow through the sensor must be halted and the sensor tubes must be completely full of
process fluid. A shutoff valve, downstream from the sensor, is recommended to halt flow during the zeroing
procedure. For more information about zeroing, refer to the instruction manual shipped with the transmitter.

Orienting the Sensor
Step 2 Orienting the Sensor
The sensor will function properly in any orientation if the sensor tubes remain filled with process fluid.
Micro Motion recommends orienting F-Series sensors as shown in Figure 9.
Figure 9 Recommended sensor orientations
Flow direction arrow
The sensor has a flow direction arrow (see Figures 1–7) to help you configure the transmitter for flow
direction. If possible, install the sensor so that the flow direction arrow matches actual process flow.
Vertical pipeline
If the sensor is installed in a vertical pipeline, liquids and slurries should flow upward through the sensor.
Gases may flow upward or downward.

Mounting the Sensor
Step 3 Mounting the Sensor
Use your common practices to minimize torque and bending load on process connections. Figure 10 illustrates
how to mount the sensor. To reduce the risk of condensation or excessive moisture, the conduit opening
should not point upward (if possible). The conduit opening of the junction box or core processor can be
rotated freely to facilitate wiring.
Figure 10 Mounting an F-Series sensor
Mounting Model F300A electronics
The electronics of a Model F300A sensor are mounted at the end of a flexible conduit. In addition to
mounting the sensor housing in the pipeline as shown in Figure 10, the Model F300A electronics need to be
mounted to a wall or instrument pole (see Figure 11). A mounting bracket is shipped with the sensor for use in
securing the electronics to a wall or instrument pole.
To mount the electronics:
1. Use four 5/16″(8 mm) bolts or two 5/16″(8 mm) U-bolts to mount the bracket to a wall or
instrument pole.
2. Slide the core processor, junction box, or Model 1700/2700 transmitter into the bracket groove.
3. Secure the electronics to the bracket with the four #10 screws provided.

Hazardous area installations
If you are installing the sensor in a hazardous location, verify that the hazardous classification information
printed on the sensor tag matches the environment in which the sensor will be installed.
Installation options
The sensor has one of the following electronics configurations:
• A Model 1700/2700 or IFT9701 transmitter. No wiring is required between the sensor and the
transmitter. Skip to Grounding on page 21.
• A core processor to a 4-wire remote transmitter (requires 4-wire cable); see Core processor to a 4-wire
remote transmitter on page 18.
• A core processor to a remote host (requires 4-wire cable); refer to the Micro Motion MVD™Direct
Connect™Flowmeter Installation Manual.
• A junction box to a 9-wire remote transmitter (requires 9-wire cable); see Junction box to a 9-wire
remote transmitter or remote core processor on page 21.
WARNING
Failure to comply with the requirements for intrinsic safety in a hazardous area
could result in an explosion.
• Make sure the hazardous area specified on the sensor approval tag (Figures 1–7)
is suitable for the environment in which the sensor will be installed.
• For installations in an area that requires intrinsic safety, use this document along
with Micro Motion approval documentation, shipped with the sensor or available on
the Micro Motion web site at www.micromotion.com.
• For hazardous installations in Europe, refer to standard EN 60079-14 if national
standards do not apply.
CAUTION
Failure to seal the sensor and transmitter housings could cause electronics to
be exposed to moisture, which could result in measurement error or flowmeter
failure.
• Close and fully tighten all covers.
• Ensure the integrity of gaskets and O-rings.
• Grease all O-rings before sealing.
• Install drip legs in cable or conduit.
• Seal all conduit openings.

18 Sensor Installation: F-Series
Wiring
Core processor to a 4-wire remote transmitter
Follow the steps below to connect the 4-wire cable between the core processor and the transmitter.
1. Use one of the following methods to shield the wiring from the core processor to the transmitter:
• If you are installing unshielded wiring in continuous metallic conduit that provides 360°
termination shielding for the enclosed wiring, go to page 20 (step 6 of the wiring procedure).
• If you are installing a user-supplied cable gland with shielded cable or armored cable, terminate
the shields in the cable gland. Terminate both the armored braid and the shield drain wires in the
cable gland. Never connect the drain wires to the internal ground screw of the core processor. Go
to page 20 (step 6 of the wiring procedure).
• If you are installing a Micro Motion-supplied cable gland at the core processor housing:
- Prepare the cable and apply shielded heat shrink as described below. The shielded heat shrink
provides a shield termination suitable for use in the gland when using cable whose shield
consists of foil and not a braid. Proceed to step 2 of the wiring procedure, below.
- With armored cable, where the shield consists of braid, prepare the cable as described below,
but do not apply heat shrink. Proceed to step 2 of the wiring procedure, below.
2. Remove the cover from the core processor housing.
3. Slide the gland nut and the clamping insert over the cable.
Figure 12 Micro Motion cable gland and heat shrink
4. For connection at the core processor housing, prepare shielded cable as follows (for armored cable,
omit steps d, e, f, and g):
a. Strip 4 1/2 inches (114 mm) of cable jacket.
b. Remove the clear wrap that is inside the cable jacket, and remove the filler material between the
wires.
c. Remove the foil shield that is around the insulated wires, leaving 3/4 inch (19 mm) of foil or braid
and drain wires exposed, and separate the wires.
d. Wrap the shield drain wire(s) around the exposed foil twice. Cut off the excess wire.

5. Insert the wires through the gland body and assemble the gland by tightening the gland nut. If desired,
leave sufficient wire length inside the core processor housing to allow the housing to rotate without
damaging the wires.
6. Identify the wires in the 4-wire cable. The 4-wire cable supplied by Micro Motion consists of one pair
of 18 AWG (0,80 mm2) wires (red and black), which should be used for the VDC connection, and one
pair of 22 AWG (0,35 mm2) wire (green and white), which should be used for the RS-485 connection.
Connect the four wires to the numbered slots on the core processor (Figure 17).
Figure 17 Connecting the wires at the core processor
7. Reinstall and tighten the core processor housing cover.
8. Additional wiring instructions for the transmitter can be found in the transmitter manual.
Note: Never ground the 4-wire cable shield and shield drain wire(s) at the transmitter.
