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.

2.1 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.

8 Micro Motion ELITE

Installation Manual Planning

20002158 October 2020

• 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.

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.

• 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/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.

• 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 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.
