1 Before you begin
1.1 About this document
This document provides information on planning, mounting, wiring, and grounding the
G-Series 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
WARNING
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 Planning
2.1 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.
WARNING
Failure to abide by approvals can cause an explosion resulting in injury or death.
□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 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
•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.
•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.
•The sensor does not require external supports. The flanges will support the sensor in
any orientation.
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 technical support.
WARNING
Temperature limits may be further restricted by hazardous area approvals that are
necessary to avoid potential injury to personnel and damage to equipment. Refer to the
hazardous area approvals documentation shipped with the sensor for specific
temperature ratings for each model and configuration.
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.
