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
WARNING
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

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.

□ 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
• 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.

Installation Manual
20002158 June 2022
• 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.)
Planning
2.2.1 High temperature best practices
• Perform steam injection downstream of the Coriolis meter
• Use steam traps to eliminate condensation and steam flashing
• Control fast acting valves to prevent hammer shock
• Install the meter symmetrically (not tilted)
• Use heat jacket symmetrically (avoid electric or oil trace on just one side)
• To avoid plugging for plugging prone applications, apply heat slowly and uniformly
during startup
• Perform slow and controlled switch-over from ethane to de-coking process
For more information, refer to the Micro Motion High Temperature Solutions Best
Practices Guide.
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 °C) or above 140 °F (60 °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 °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 selfdraining 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 Micro Motion ELITE Coriolis Flow and Density Meters 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.
