1.1 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.
□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.

1.2 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. (Some sensor models installed in very small, flexible pipeline have
optional installation instructions that allow for external supports.)
1.3 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.
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.
•Temperature limits may be further restricted by hazardous area approvals. Refer to the
hazardous area approvals documentation shipped with the sensor or available at
www.emerson.com.
•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),
please 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)

1.4 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 http://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.

Topics covered in this chapter:
•Recommendations for lifting heavy meters
•Mount the sensor
•Rotate junction box or 800 core processor (optional)
•Mount electronics of high-temperature sensors
•Mount a CMF010 sensor to a wall or pole
•Mount a CMFS007, CMFS010 or CMFS015 sensor in a bracket

•Secure wafer-style process connections
•Attach extended electronics
2.1 Recommendations for lifting heavy meters
Heavy meters (those over 50 lb. [22 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 – know and follow all safety practices and regulations for your facility and
for any lifting/rigging equipment being used
•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

2.2 Mount the sensor
Use your common practices to minimize torque and bending load on process connections.
Tip
To reduce the risk of condensation problems, do not orient transmitters or sensor junction boxes
with their conduit openings pointing upward.
CAUTION!
Do not lift the sensor by the electronics or purge connections. Lifting the sensor by the
electronics or purge connections can damage the device.
Mounting the sensorFigure 2-3:
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 very small, flexible pipeline have optional installation
instructions that allow for external supports.)

Note
The 800 core processor is shown in this figure. The junction box has a somewhat different appearance.
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.

2.4 Mount electronics of high-temperature sensors
The electronics of high-temperature sensors are attached to the end of a 32" (812 mm)
pre-installed flexible conduit. The electronics must be separately mounted on a wall or
instrument pole.

With some large meter sizes, the meter may ship with the electronics attached to the
sensor case. The meter cannot be operated in this configuration. Detach the electronics
bracket from the sensor case and then proceed to mount the electronics to a wall or
instrument pole as described below.
Important
Do not operate the meter while the electronics are attached to the sensor case.

2.5 Mount a CMF010 sensor to a wall or pole
The CMF010 sensor has an optional mounting configuration for use with small or flexible
pipeline. If the pipeline adequately supports the sensor, you can skip this procedure.
1. Locate the optional mounting holes. For sensors with a junction box, the junction
box must be rotated to the side to expose the mounting holes.
