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.

1.3.1

□ 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 in (203 mm) to 10 in (254 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.

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.

Planning

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.

1.5 Temperature limits

Temperature type Min Max

Process temperature -40 °F (-40.0 °C) 356 °F (180.0 °C)

Ambient temperature -40 °F (-40.0 °C) 176 °F (80.0 °C)

Use the extended mount junction box (electronic interface code H) for process
temperatures above 176 °F (80.0 °C).

3 Wiring

3.1 Tantalum wiring

• A 9-wire cable is limited to 1,000 ft (304.80 m) between the sensor and the

transmitter.

• If you are using the Smart Meter Verification (SMV) application, the 9-wire cable is

limited to 60 ft (18.29 m) 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

Procedure

1. Prepare and install the cable according to the instructions in the Micro Motion 9-Wire

Flowmeter Cable Preparation and Installation Guide.

Installation Manual Grounding

MMI-20040393 April 2019

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 60079-14 is applicable to most installations, in particular Sections

16.2.2.3 and 16.2.2.4.

• 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 (2.08 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.

Installation Manual Purge the sensor case

MMI-20040393 April 2019

5 Purge the sensor 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

Whenever a purge plug is removed from the sensor case, you must repurge the 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 7.25 psi (0.5 bar).

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.
