1 Before you begin
1.1 About this document
This document provides information on planning, mounting, wiring, and grounding the
ELITE 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
□If you plan to mount the transmitter in a hazardous area:
WARNING
Make sure that the hazardous area specified on the approval tag is suitable for the
environment in which the meter will be installed.
□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.
Table 2-1: Maximum lengths for Micro Motion cable

Signal (RS-485) 22 AWG (0.326 mm²) or larger 1,000 ft (305 m)
□For optimal performance, install the sensor in the preferred orientation. The sensor will
work in any orientation as long as the flow tubes remain full of process fluid.

□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.
Planning Installation Manual
October 2021 20002158

•The sensor does not require external supports. The flanges will support the sensor in
any orientation. (Some sensor models installed in very small, flexible pipeline have
optional installation instructions that allow for external supports.)
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 with your Micro Motion representative.
WARNING
Temperature limits may be further restricted by hazardous area approvals that are
necessary to avoid potential injury to personnel and damage to equipment. Refer to the
hazardous area approvals documentation shipped with the sensor or available at
www.emerson.com/flowmeasurement for specific temperature ratings for each model
and configuration.
Note
•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
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.
•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.
•For the CMFS007 sensor, the difference between the process fluid temperature and the
average temperature of the case must be less than 210 °F (99 °C)

2.4 Recommendations for hygienic and self-
draining applications
CMFS sensors are certified EHEDG TYPE EL CLASS I for hygienic applications when installed
vertically with the process fitting and gasket combinations listed in the Position Paper of
the EHEDG Test Methods Subgroup (available at https://www.ehedg.org). Other process
connections/gasket combinations may be used provided they have been evaluated and
successfully tested for in-place cleanability according to the latest edition of EHEDG
Document 2. Refer to the ELITE Product Data Sheet for further information about fitting
options.
For optimal cleanability and drainability:
•If possible, install the sensor in a vertical pipeline with the process fluid flowing upward
through the sensor.
•If the sensor must be installed in a horizontal pipeline, drainage is accomplished by air
purge evacuation of the pipeline circuit.
•For clean-in-place (CIP) applications, Micro Motion recommends using the generally-
accepted flow velocity of at least 1.5 m/s for cleaning the sensor.
•The gap between the electronics housing and sensor body should be inspected
periodically. Manually clean this gap when necessary.

3 Mounting
3.1 Recommendations for lifting heavy meters
Heavy meters (those over 50 lb (23 kg), and even lighter meters that must be installed in
elevated or difficult-to-reach places, usually require additional consideration when
transporting or lifting them into their installation location.
•Safe handling during transportation and installation is the responsibility of the installer
CAUTION
Know and follow all safety practices and regulations for your facility and for any
lifting/rigging equipment being used in order to prevent injury.
•A professional rigging crew with proper equipment should be used
•Typical equipment for handling heavy meters includes the following:
—Fixed hoist boom trucks or cranes
—Continuous web belt slings
—Eye to eye web belt slings
—Two leg wire rope slings
•Lift a meter by its case.
•Do not lift a meter by its electronics (junction box, transmitter, or any electrical fittings)
or by its purge fittings
•It may be useful to identify the meter center of gravity
•Protect the sealing surfaces on the process fittings with factory-installed flange
protectors or comparable field-installed protection

3.2 Mount the sensor
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.Some sensor models installed in small, flexible pipelines have optional
installation instructions that allow for external supports.

Procedure
1. Loosen the clamping ring screw and remove the clamping ring.
2. Gently separate the housing from the feedthrough, but only until there is sufficient
clearance from the alignment notches to rotate the housing.
3. Rotate the housing to the desired position and in line with the alignment notches.
4. Seat the housing onto the feedthrough.
5. Replace the clamping ring and tighten the clamping ring screw.

3.4 Mount electronics of high-temperature sensors
The electronics of high-temperature sensors are attached to the end of a 32 in (813 mm)
pre-installed flexible conduit. The electronics must be separately mounted on a wall or
instrument pole.
