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.
Table 1-1: Maximum cable lengths
Cable type To transmitter Maximum length
Micro Motion 9-wire 9739 MVD transmitter 1,000 ft (305 m)
All other MVD transmitters 60 ft (18 m)
Micro Motion 4-wire All 4-wire MVD transmitters — 1,000 ft (305 m) without
Ex-approval
— 500 ft (152 m) with IIC
rated sensors
— 1,000 ft (305 m) with IIB

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.)
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.
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 (-40.0 °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 from the
Micro Motion web site (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)), please ensure electronics are not enclosed in
insulation as this may lead to electronics failure.
