1 Before you begin
1.1 About this document
This document provides information on planning, mounting, wiring, and grounding the F-
Series sensor.
The information in this document assumes that users understand basic transmitter and
sensor installation, configuration, and maintenance concepts and procedures.
1.2 Hazard messages
This document uses the following criteria for hazard messages based on ANSI standards
Z535.6-2011 (R2017).
DANGER
Serious injury or death will occur if a hazardous situation is not avoided.
WARNING
Serious injury or death could occur if a hazardous situation is not avoided.
CAUTION
Minor or moderate injury will or could occur if a hazardous situation is not avoided.
NOTICE
Data loss, property damage, hardware damage, or software damage can occur if a
situation is not avoided. There is no credible risk of physical injury.
Physical access
NOTICE
Unauthorized personnel can potentially cause significant damage and/or misconfiguration
of end users' equipment. Protect against all intentional or unintentional unauthorized use.
Physical security is an important part of any security program and fundamental to
protecting your system. Restrict physical access to protect users' assets. This is true for all
systems used within the facility.

2 Planning
2.1 Installation checklist
□Make sure that the hazardous area specified on the approval tag is suitable for the
environment in which the meter will be installed.
WARNING
Failure to abide by approvals can cause an explosion resulting in injury or death.
□Verify that the local ambient and process temperatures are within the limits of the
meter.
□If your sensor has an integral transmitter, no wiring is required between the sensor and
transmitter. Follow the wiring instructions in the transmitter installation manual for
signal and power wiring.
□If your transmitter has remote-mounted electronics, follow the instructions in this
manual for wiring between the sensor and the transmitter, and then follow the
instructions in the transmitter installation manual for power and signal wiring.

applications
□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 Best practices
The following information can help you get the most from your sensor.
•There are no pipe run requirements for Micro Motion sensors. Straight runs of pipe
upstream or downstream are unnecessary.
•If the sensor is installed in a vertical pipeline, liquids and slurries should flow upward
through the sensor. Gases should flow downward.
•Keep the sensor tubes full of process fluid.
•For halting flow through the sensor with a single valve, install the valve downstream
from the sensor.
•Minimize bending and torsional stress on the meter. Do not use the meter to align
misaligned piping.
•The sensor does not require external supports. The flanges will support the sensor in
any orientation.
2.3 Temperature limits
Sensors can be used in the process and ambient temperature ranges shown in the
temperature limit graphs. For the purposes of selecting electronics options, temperature
limit graphs should be used only as a general guide. If your process conditions are close to
the gray area, consult technical support.
Notes
•In all cases, the electronics cannot be operated where the ambient temperature is
below -40 °F (-40.0 °C) or above 140 °F (60.0 °C). If a sensor is to be used where the
Planning Installation Manual
April 2020 20002298
8 Micro Motion F-Series

ambient temperature is outside of the range permissible for the electronics, the
electronics must be remotely located where the ambient temperature is within the
permissible range, as indicated by the shaded areas of the temperature limit graphs.
•Temperature limits may be further restricted by hazardous area approvals. Refer to the
hazardous area approvals documentation shipped with the sensor or at
www.emerson.com/flowmeasurement.
•The extended-mount electronics option allows the sensor case to be insulated without
covering the transmitter, core processor, or junction box, but does not affect
temperature ratings. When insulating the sensor case at elevated process
temperatures above 140 °F (60.0 °C), ensure electronics are not enclosed in insulation
as this may lead to electronics failure.

3 Mounting
3.1 Mount the sensor
Use common practices to minimize torque and bending load on process connections.
NOTICE
•Lifting the sensor by the electronics or purge connections can damage the device.
•To reduce the risk of collecting liquid in the electronics housing, do not orient
transmitters or sensor junction boxes with their conduit openings pointing upward.
Procedure
Mount the sensor.
Notes
•Do not use the sensor to support the piping.
•The sensor does not require external supports. The flanges will support the sensor in
any orientation.
3.2 Attach extended electronics
If your installation has a sensor with extended electronics, you will need to install the
extender onto the sensor case.
Extended core processors are matched at the factory to specific sensors. Keep each core
processor together with the sensor with which it was shipped.

4 Wiring
4.1 Options for wiring
The wiring procedure you follow depends on which electronics option you have.
Table 4-1: Wiring procedures by electronics option
Electronics option Wiring procedure
Integral transmitter The transmitter is already connected to the sensor. No wiring is
required between sensor and transmitter. See the transmitter
installation manual for wiring the power and signal cable to the
transmitter.
Extended electronics The electronics are separated from the sensor by an extender and
must be attached as described in Attach extended electronics.
There is no wiring required because the physical connection
includes the electrical connection.
MVD™ Direct Connect ™There is no transmitter to wire. See the Micro Motion MVD Direct
Connect Meters manual for wiring the power and signal cable
between the sensor and the direct host.
Integral core processor with
remote transmitter
The core processor is already connected to the sensor. Connect a
4-wire cable between the core processor and transmitter. Refer
to Connect 4-wire cable.
Remote core processor

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.

5 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.
