1.1 About this document
This manual provides information on planning, mounting, and grounding the meter. For
information on full configuration, maintenance, troubleshooting, or service of the
transmitter, see the configuration and use manual.
The information in this document assumes that users understand:
•Basic transmitter and sensor installation, configuration, and maintenance concepts
and procedures
•All corporate, local government, and national government safety standards and
requirements that guard against injuries and death

All documentation resources are available at www.emerson.com or on the user
documentation DVD.
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.

Preferred sensor orientationTable 1-1:
Liquids
Gases
Slurries
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.

Process temperature -40 ˚F (-40 ˚C) 356 ˚F (180 ˚C)
Ambient temperature -40 ˚F (-40 ˚C) 212 ˚F (100 ˚C)
Use the extended mount junction box (electronic interface code H) for process
temperatures above 212 ˚F (100 ˚C).

2 Mounting
2.1 Mount the meter
Use your common practices to minimize torque and bending load on process connections.
Prerequisites
Read the installation checklist and best practices if you have not yet done so already. See
Section 1.3 and Section 1.4.
Procedure
Mount the meter using the following illustration.

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.
