1.1 About this document
This document provides information on planning, mounting, wiring, and grounding the TSeries 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
□ 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.

500 ft (152 m) with IIC-rated sensors
1,000 ft (305 m) with IIB-rated sensors
□ 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.
• 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.
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.

Ambient and process temperature limits for all models
A. Ambient temperature of core processor or transmitter in °F (°C)
B. Maximum process temperature in °F (°C)
C. Mount transmitter remotely and use a junction box
D. Temperature is below -40 °F (-40 °C); mount transmitter remotely and use a junction box
2.4 Recommendations for hygienic and selfdraining applications
For optimal cleanability and drainability:
• If possible, install the sensor in a vertical pipeline with the process fluid flowing upward
through the sensor.
• The minimum angle of inclination of the sensor depends on the process fitting. See
Figure 2-1 and Table 2-3.
• 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.
• If the process piping must be larger than the sensor, eccentric reducers may be used to
ensure full drainability. In this case, the process end connections for the piping and
sensor must be the same size. See Figure 2-2.
Note
As part of the cleaning process, you can purge skid-based systems with nitrogen at the
end of the cleaning cycle. When using eccentric reducers, it is possible to trap gas in
the section of process piping adjacent to the reducer. Sensor performance can be
impacted by intermittent flow of the captured gas in a liquid fluid stream.
