iv Micro Motion® Model D and DT Sensors Instruction Manual
Before You Begin
Your new sensor
Your new Micro Motion® Model D or DT sensor, or D600 sensor and
booster amplifier, is one part of a Coriolis flowmetering system. The
other part is a transmitter.
Transmitter connections
Model D sensors are available with a factory-supplied 9-wire junction
box for connecting to a remotely mounted transmitter, or to a remotely
mounted core processor.
Model DT sensors are available with a 3-foot (1-meter) pigtail of cable
that connects to a user-supplied junction box. The junction box connects
to a remotely mounted transmitter, or to a remotely mounted core
processor.
The D600 has a booster amplifier. The booster amplifier is available with
a factory-supplied 9-wire junction box for connecting to a remotely
mounted transmitter, or with a factory-supplied core processor for
connecting to a 4-wire remotely mounted transmitter or to a usersupplied remote host.
All Model D and DT sensors may be connected to the Micro Motion
transmitters listed in Table 1. The D600 sensor may be connected to the
transmitters listed in Table 2.

Keys for sensor location
The sensor may be located anywhere in the process line, as long as
the following conditions are met:
• Before operation, you must be able to stop flow through the sensor.
(During the zeroing procedure, flow must be stopped completely, and
the sensor must be full of process fluid.)
• The sensor must be installed in an area that is compatible with the
classification specified on the sensor approvals tag. (See
illustrations, pages 3-6.)

Valves
For ATEX approvals, process fluid temperature can be further restricted
by ambient temperatures. For guidelines, go to www.micromotion.com/
atex.
D600 booster amplifier ambient temperature limits
Install the booster amplifier in a location that falls within the following
limits:
Ambient temperature limits between –58 to +140°F (–50 to +60 °C).
For ATEX approvals, process fluid temperature can be further restricted
by ambient temperatures. For guidelines, go to www.micromotion.com/
atex.
After the sensor and transmitter have been fully installed, you must
perform the zeroing procedure. During the zeroing procedure, flow
through the sensor must be halted and the sensor tubes must be
completely full of process fluid. A shutoff valve, downstream from the
sensor, is required to halt flow during the zeroing procedure. For more
information about zeroing, see page 39.

Hazardous area installations
Make sure the hazardous area specified on the sensor approvals tag is
suitable for the environment in which the sensor is installed. (See
illustrations on pages 3-6.) For installation in an area that requires
intrinsic safety, refer to Micro Motion hazardous approval
documentation, shipped with the sensor or available from the Micro
Motion web site.
For hazardous installations in Europe, refer to standard EN 60079-14 if
national standards do not apply.

Installation
Keys for sensor orientation
The sensor will function properly in any orientation if the sensor flow
tubes remain filled with process fluid.
Step 2 Orientation
Flow direction
Process fluid
Micro Motion sensors measure accurately regardless of flow direction as
long as the sensor flow tubes remain filled with process fluid.
Flow direction arrow
The sensor has a flow direction arrow (see illustrations, pages 3-6) to
help you configure the transmitter for flow direction. Process fluid flowing
in the direction opposite to the flow direction arrow may cause
unexpected transmitter output unless the transmitter is configured
appropriately. For instructions on configuring the transmitter’s flow
direction parameter, refer to the transmitter instruction manual.
Vertical pipeline
If the sensor is installed in a vertical pipeline, liquids and slurries should
flow upward through the sensor. Gases may flow upward or downward.
Typical sensor orientations are shown in the tables on the following
pages:
• For measuring liquids, see page 14.
• For measuring gases, see page 15.
• For measuring slurries, see page 16.

CAUTION
Keys for sensor mounting
Use your common piping practices to minimize:
• Torque on process connections
• Bending load on process connections
• For proper orientation, see pages 14-16
• For optional D600 mounting, see page 18
Step 3 Mounting
Mounting any D or DT sensor
Using the sensor to support piping
can damage the sensor or
cause measurement error.
Do not use sensor to support pipe.
Micro Motion® Model D and DT Sensors Instruction Manual 17
Mounting continued
Snub-mount connector
• Connect support only to the factory-supplied
rubber snub-mount connector
• Attach with 1/2"-13 UNC bolt
• Bolt may penetrate isolator to 1 1/2" (40 mm)
D600 in flag-mount orientation can use
snub connector for added support in
high-vibration installations
Conduit openings If possible, install wiring with the conduit openings pointed downward to
reduce the risk of condensation or excessive moisture in the housing.
Otherwise, install drip legs on the cable or conduit.
Optional Model D600 mounting
When installing a Model D600 in a high-vibration area, additional
support may be added if desired. Use the D600 snub-mount connector
with vibration isolator to help support the sensor. See illustration, below.
Typically, the snub-mount connector is used when the D600 is installed
in the flag-mount orientation (in a vertical pipeline), as shown below.
Model D600 mounting with snub-mount connector
DT sensors
Model DT sensors come with a 3-foot (1-meter) pigtail of cable
pre-installed. A junction box can be connected at the end of this pigtail.
The junction box is used for connecting the cable from the transmitter.

WARNING
Step 4 Wiring
Hazardous area installations
Model D sensor junction box
The following warning applies to hazardous area installations
Failure to comply with requirements for intrinsic
safety in a hazardous area could result in an
explosion.
• Make sure the hazardous area specified on the sensor
approvals tag is suitable for the environment in which the
sensor is installed. See illustrations, pages 3-6.
• For installation in an area that requires intrinsic safety,
refer to Micro Motion hazardous approval installation
instructions.
• For hazardous area installations in Europe, refer to
standard EN 60079-14 if national standards do not apply.
Most Model D sensors are shipped with a junction box for wiring. There
are two types of junction boxes: one for the D600 sensor, one for all the
other D sensors.
• The D600 junction box is different than the junction box for other D
sensors. D600 sensors are also available with a core processor. For
more information on the D600 sensor, see page 24.
• Model DT sensors can use a junction box. For more information on the
DT sensor junction box, see page 20.
For Model D sensors (except the DT series and D600):
• If it if not already installed, install the junction box on the sensor,
following the wiring instructions on the junction box.
• If possible, install wiring with the junction-box opening pointed
downward, or with a drip leg in the conduit or cable, to reduce the risk
of condensation or excessive moisture in the junction box. See
illustration on page 20.
• Next, follow the guidelines in Connecting and shielding 9-wire cable to
wire the sensor to the transmitter.
