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.
Full flow tubes
For optimal performance, the sensor tubes should remain full of process fluid.
Hazardous area installations
Make sure the hazardous area specified on the sensor approval tag is suitable for the environment in which the
appropriate Micro Motion approval documentation, shipped with the sensor or available from the
Micro Motion web site at www.micromotion.com.
Improper installation in a hazardous area can cause an explosion. When installing in a hazardous area, refer to Micro Motion approvals instructions, shipped with the product or available from the Micro
Motion web site. For hazardous installations in Europe, refer to standard EN 60079-14 if national standards do not apply.
Environmental limits
The ambient and process temperature limits of the sensor are shown in Figures 6 and 7:
• For F-Series sensor models other than high-temperature and extreme-high temperature models, see
• For high-temperature and extreme high-temperature F-Series sensors, see Figure 7.

Determining a Location
Maximum wiring distances
If the transmitter is mounted remotely from the sensor, the maximum distance between the sensor and
transmitter depends on cable type. See Table 2.
For high-temperature and extreme high-temperature F-Series sensors, note the following:
• For sensors with a Model 1700/2700 transmitter, the transmitter is considered to be integrally mounted
on the sensor, so Table 2 does not apply.
• For sensors with a junction box or core processor, the limits in Table 2 apply only to the wiring
between the junction box or core processor and a remotely mounted transmitter. The length of the flexible conduit on which the junction box or core processor is mounted does not need to be considered.

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.
Sensor Installation: F-Series 11
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.

Step 4 Wiring
Improperly sealed housings can expose electronics to moisture, which can cause measurement error or flowmeter failure. Inspect and grease all gaskets and O-rings. Fully close and tighten all housing covers and conduit openings.
Installation options
The sensor has one of the following electronics configurations:
• An integral Model 1700/2700 or IFT9701 transmitter. No wiring is required between the sensor and
the transmitter. Skip to Grounding on page 19.
• A core processor to a remote host (requires 4-wire cable); refer to the Micro Motion MVD ™ Direct
Connect ™ Flowmeter Installation Manual.
remote transmitter or remote core processor on page 18.
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 17 (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 17 (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.

4. For connection at the core processor housing, prepare shielded cable as follows (for armored cable,
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.
Figure 12 Wrapping the shield drain wires e. Place the shielded heat shrink over the exposed shield drain wire(s). The tubing should completely cover the drain wires.
f. Without burning the cable, apply heat (250 °F or 120 °C) to shrink the tubing.

1. Prepare and install the cable according to the instructions in Micro Motion’s 9-Wire Flowmeter Cable
Preparation and Installation Guide.
2. Insert the stripped ends of the individual wires into the terminal blocks. No bare wires should remain exposed.
3. Match the wires color for color. For wiring at the transmitter or remote core processor, refer to the transmitter documentation.
4. Tighten the screws to hold the wires in place.
5. Ensure integrity of gaskets, then tightly close and seal the junction box cover and all housing covers on the transmitter or core processor.
18 Sensor Installation: F-Series
Grounding
Step 5 Grounding
The sensor can be grounded via the piping if the joints in the pipeline are ground-bonded. If the sensor is not grounded via the piping, connect a ground wire to the internal or external grounding screw, which is located on the core processor housing or junction box.
Improper grounding can cause measurement error. Ground the flowmeter to earth, or follow ground network requirements for the facility.
If national standards are not in effect, follow these guidelines to ground the sensor:
• Use copper wire, 14 AWG (2,0 mm²) or larger wire size for grounding.
• Keep all ground leads as short as possible, less than 1 ohm impedance.
• Connect ground leads directly to earth, or follow plant standards.

Sensor Installation: F-Series 19
Purge Fittings
Purge Fittings
If the sensor has purge fittings, they should remain sealed at all times. After a purge plug has been removed, the sensor case should be purged with argon or nitrogen and resealed.
Purging the case protects internal components. The sensor is purged of all oxygen and sealed at the factory. If the purge plugs are never removed, it is not necessary to purge or re-seal the sensor. For more information, contact Micro Motion Customer Service.
Removing a purge plug
If a purge plug is removed from the sensor case, it will be necessary to repurge the case.
Removing a purge plug compromises the secondary containment of the sensor and could expose the user to process fluid. Take all necessary precautions when removing purge plugs.
Improper pressurization of the sensor case could result in personal injury. Removing a purge plug will require the sensor case to be repurged with a dry inert gas. Follow all instructions provided in the case purging procedure.
Case purging procedure
Read all instructions before performing the case purging procedure. It is not necessary to perform this procedure unless a purge plug has been removed.
1. Shut down the process, or set control devices for manual operation.
Performing the purge procedure while the flowmeter is operating could affect measurement accuracy, resulting in inaccurate flow signals. Before performing the case purging procedure, shut down the process, or set control devices for manual operation.
2. Remove both purge plugs from the sensor case. If purge lines are being used, open the valve in the purge lines.
3. Prepare the purge plugs for reinstallation by wrapping them with 3–5 turns of Teflon ® tape.
4. Connect the supply of nitrogen or argon gas to the inlet purge connection or open inlet purge line.
Leave the outlet connection open.
• Exercise caution to avoid introducing dirt, moisture, rust, or other contaminants into the sensor case.
• If the purge gas is heavier than air (for example, argon), locate the inlet lower than the outlet, so the purge gas will displace air from bottom to top.
• If the purge gas is lighter than air (such as nitrogen), locate the inlet higher than the outlet, so the purge gas will displace air from top to bottom.
5. Make sure there is a tight seal between the inlet connection and sensor case, so air cannot be drawn by suction into the case or purge line during the purging process.
6. The purge time is the amount of time required for full exchange of atmosphere to inert gas. For each
purge time to fill the additional volume of the purge line.
7. Avoid pressurizing the sensor case. At the appropriate time, shut off the gas supply, then immediately seal the purge outlet and inlet connections with the purge plugs. If pressure inside the case elevates above atmospheric pressure during operation, the flowmeter density calibration will be inaccurate.
