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.

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.)

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.)

Planning

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)

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 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.

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
