1 Before you begin

1.1 About this document

This document provides information on planning, mounting, wiring, and grounding the T-

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

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.

□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.

2.4 Recommendations for hygienic and self-

draining 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.

20002172 February 2020

Installation Manual 9

•The gap between the electronics housing and sensor body should be inspected

periodically. Manually clean this gap when necessary.

•Tri-Clamp® and DIN 11851 style process connections require special gaskets to comply

with EHEDG requirements for hygienic design.
