• Installation checklist

• Best practices

• Temperature limits

• Recommendations for hygienic and self-draining applications

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.

For the wiring between the sensor and the transmitter, consider maximum cable

□

lengths. The maximum distance between the sensor and transmitter depends on
the cable type. For all types of wiring, Micro Motion recommends using Micro
Motion cable.

Planning

Maximum lengths for Micro Motion cableTable 1-1:

Cable type To transmitter Maximum length

Micro Motion 9-wire 9739 MVD transmitter 1000 ft (300 m)

All other MVD transmitters 60 ft (20 m)

Micro Motion 4-wire All 4-wire MVD transmitters 1000 ft (300 m)

Maximum lengths for user-supplied 4-wire cableTable 1-2:

Wire function Wire size Maximum length

Power (VDC) 22 AWG (0,35 mm2) 300 ft (90 m)

20 AWG (0,5 mm2) 500 ft (150 m)

18 AWG (0,8 mm2) 1000 ft (300 m)

Signal (RS-485) 22 AWG (0,35 mm2) or larger 1000 ft (300 m)

Installation Manual 1

Planning

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.

Preferred sensor orientationTable 1-3:

Alternate orientations

Slurries

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.

2 Micro Motion ELITE

• 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 may flow upward or 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 areas, it may be inappropriate to use electronics
options other than a junction box. Consult consult with your Micro Motion
representative.

• 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 area 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
from the Micro Motion web site (www.micromotion.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.

1.4 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 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.
