Planning

2.1 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

2.2 Installation checklist

•  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:
  WARNING
  — 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 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.

2.2.1 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.

2.3 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.

2.4 Temperature limits

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

Mounting

3.1 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 Installation checklist and Best practices.
Procedure
Mount the meter using the following illustration.

Wiring

4.1 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.

WARNING
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 resulting in injury or death.

NOTICE
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.

4.1.1 Connect the 9-wire cable
Procedure

1. Prepare and install the cable according to the instructions in the Micro Motion 9-Wire Flow Meter 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.
   Terminal block number| Wire color
   ---|---
   1| Blue
   2| Gray
   3| Green
   4| White
   5| Orange
   6| Yellow
   7| Purple
   8| Red
   9| Brown
   shield|
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.
6. Refer to the transmitter installation manual for signal and power wiring instructions.

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.

NOTICE
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.

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 purge the case again.
Procedure

1. Shut down the process, or set control devices for manual operation.
   NOTICE
   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.
   WARNING
   • If a rupture disk has been installed on the purge fitting, stay clear of the rupture disk pressure relief area. High-pressure fluid escaping from the sensor can cause severe  injury or death. Orient the sensor 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 injury.
   NOTICE
   If a rupture disk has been installed on the purge fitting, 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.
   NOTICE
   • 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.
   Important
   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.
