1.3 Installation checklist
□Safety messages are provided throughout this content to protect personnel and
equipment. Read each safety message carefully before proceeding to the next step.
□If possible, install the meter in a location that will prevent direct exposure to
sunlight. The environmental limits for the meter may be further restricted by
hazardous area approvals.
□If you plan to mount the meter in a hazardous area:
-Verify that the meter has the appropriate hazardous area approval. Each meter
has a hazardous area approval tag attached to the meter housing.
-For ATEX/IECEx installations, strictly adhere to the safety instructions
documented in the ATEX/IECEx approvals documentation available on the
Product Documentation DVD shipped with the product or at www.emerson.com.
Be sure to reference this documentation in addition to the information shown in
this guide.
□Verify that the local ambient and process temperatures are within the limits of the
meter.
□Follow the wiring instructions in the Model 5700 installation manual for signal and
power wiring.
□Mount the meter in a location and orientation that allows sufficient clearance to
open the housing cover. Allow 8–10 inches (200–250 mm) clearance at the wiring
access points.
□Install the meter so that the flow direction arrow on the sensor case matches the
actual forward flow of the process. Flow direction is also software-selectable.
1.3.1 Orientation options
You can mount the meter in any orientation as long as the conduit openings or display do
not point upward. Keep the sensor tubes full of process fluid to achieve best performance.
CAUTION!
Installing the meter with the conduit openings or display facing upward risks moisture
entering the housing, which could damage the meter.

1.4 Best practices
•There are no pipe run requirements for Emerson meters. Straight runs of pipe
upstream or downstream are unnecessary.
•If the meter is installed in a vertical pipeline, liquids and slurries should flow upward
through the meters. Gases should flow downward.
•Keep the meter tubes full of process fluid.
•For halting flow through the meter with a single valve, install the valve downstream
from the meter.
•Minimize bending and torsional stress on the meter. Do not use the meter to align
misaligned piping.
•The meter does not require external supports. The flanges will support the sensor in
any orientation.
•Do not use the junction box to pick up the meter.
•Do not use the junction box as a step.
•Do not unscrew and rotate the junction box as this will break the wires.
•Do not install the meter in suspended pipes.
•Do not adjust the meter position by pulling or grasping the meter.

3 Wiring
3.1 Tantalum wiring
•A 9-wire cable is limited to 1000 feet (305 meters) between the sensor and the
transmitter.
•If you are using the Smart Meter Verification (SMV) application, the 9-wire cable is
limited to 60 feet (18 meters) maximum.
•Use Teflon™ jacketed cable for SMV applications.
DANGER!
Make sure the hazardous area specified on the sensor approval tag is suitable for the
environment in which the sensor will be installed. Failure to comply with the requirements for
intrinsic safety in a hazardous area could result in an explosion.
CAUTION!
Fully close and tighten all housing covers and conduit openings. Improperly sealed housings
can expose electronics to moisture, which can cause measurement error or flowmeter failure.
Inspect and grease all gaskets and O-rings.
3.1.1 Connect the 9-wire cable
1. Prepare and install the cable according to the instructions in the Micro Motion 9-
Wire Flowmeter Cable Preparation and Installation Guide.
2. Insert the stripped ends of the individual wires into the terminal blocks of the
junction box. Ensure that no bare wires remain exposed.

4 Grounding
The meter must be grounded according to the standards that are applicable at the site.
The customer is responsible for knowing and complying with all applicable standards.
Prerequisites
Use the following guides for grounding practices:
•In Europe, IEC 79-14 is applicable to most installations, in particular Sections
12.2.2.3 and 12.2.2.4.
•In the U.S.A. and Canada, ISA 12.06.01 Part 1 provides examples with associated
applications and requirements.
If no external standards are applicable, follow these guidelines to ground the sensor:
•Use copper wire, 14 AWG (2,0 mm2 ) or larger wire size.
•Keep all ground leads as short as possible, less than 1 Ω impedance.
•Connect ground leads directly to earth, or follow plant standards.
CAUTION!
Ground the flowmeter to earth, or follow ground network requirements for the facility.
Improper grounding can cause measurement error.
Procedure
Check the joints in the pipeline.
-If the joints in the pipeline are ground-bonded, the sensor is automatically grounded
and no further action is necessary (unless required by local code).
-If the joints in the pipeline are not grounded, connect a ground wire to the grounding
screw located on the sensor electronics.
Tip
The sensor electronics may be a transmitter, core processor, or junction box. The grounding
screw may be internal or external.

5 Pressure relief
Tantalum-series sensors are available with a rupture disk installed on one of the purge
fittings located on the case. Rupture disks are meant to vent process fluid from the sensor
case in the unlikely event of a flow tube breach. Some users connect a pipeline to the
rupture disk to help contain escaping process fluid. For more information about rupture
disks, contact customer service.
If the sensor has a rupture disk, it should remain installed at all times as it would otherwise
be necessary to re-purge the case. If a rupture disk is activated by a tube breach, the seal in
the rupture disk will be broken, and the Coriolis meter should be removed from service.
The rupture disk is located as follows on the meter, and the warning sticker shown is
placed next to it.
A. Purge fittings
DANGER!
Stay clear of the rupture disk pressure relief area. High-pressure fluid escaping from the sensor
can cause severe injury or death. The sensor must be oriented so that personnel and equipment
will not be exposed to any discharge along the pressure relief path.

5.1 Purge the sensor case
Whenever a purge plug is removed from the sensor case, you must repurge the case.
Prerequisites
Make sure the following are available before beginning the purge procedure:
•Teflon™ tape
•Argon or nitrogen gas sufficient to purge the sensor case
Procedure
1. Shut down the process, or set control devices for manual operation. Before
performing the case purging procedure, shut down the process or set the control
devices for manual operation. Performing the purge procedure while the flowmeter
is operating could affect measurement accuracy, resulting in inaccurate flow signals.
2. Remove both purge plugs from the sensor case. If purge lines are being used, open
the valve in the purge lines.
DANGER!
•Stay clear of the rupture disk pressure relief area. High-pressure fluid escaping from
the sensor can cause severe injury or death. The sensor must be oriented so that
personnel and equipment will not be exposed to any discharge along the pressure
relief path.
•Take all necessary precautions when removing purge plugs. Removing a purge plug
compromises the secondary containment of the sensor and could expose the user to
process fluid.
•Improper pressurization of the sensor case could result in personal injury.
CAUTION!
Be sure to use thread protectors when removing the purge fitting so as not to damage
the disk membrane surrounding the rupture disk.
3. Prepare the purge plugs for reinstallation by wrapping them with 2–3 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 (such as argon), locate the inlet lower than the
outlet, so that 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 that the purge gas will displace air from top to bottom.
5. Make sure that there is a tight seal between the inlet connection and sensor case, so
that air cannot be drawn by suction into the case or purge line during the purging
process.

6. Run purge gas through the sensor.
The purge time is the amount of time required for full exchange of atmosphere to
inert gas. The larger the line size, the greater amount of time is required to purge
the case. If purge lines are being used, increase the purge time to fill the additional
volume of the purge line.
Note
Keep the purge gas pressure below 0.5 bar (7 psi).
7. At the appropriate time, shut off the gas supply, then immediately seal the purge
outlet and inlet connections with the purge plugs.
Avoid pressurizing the sensor case. If pressure inside the case elevates above
atmospheric pressure during operation, the flowmeter density calibration will be
inaccurate.
8. Make sure that the purge fitting seals are tight so that air cannot be drawn by
suction into the sensor case.
