INTRODUCTION

The sensor and booster amplifier make up one part of a Coriolis
flowmeter. The other part is a transmitter.

Installation options

The sensor and booster amplifier are available in any of the
configurations described in Table 1. Table 1 also lists the transmitters that
can be used with each configuration.

STEP 1. Choosing a location

Choose a location for the sensor based on the requirements described in
this section.

General guidelines

The following conditions must be 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.)

• During operation, the sensor must remain 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 Figure 1 and
Figure 4).

Hazardous area installations

Make sure the hazardous areas specified on the approvals tags are suitable
for the environment in which the sensor and booster amplifier will be
installed. See Figures 1 and 4. For installation in an area that requires
intrinsic safety, refer to Micro Motion UL, CSA, or ATEX
documentation, shipped with the sensor or available from the Micro
Motion web site.

For a complete list of hazardous area classifications for Micro Motion

™

sensors, refer to the EXPERT

system at www.expert2.com.

Process fluid temperature and ambient temperature can be further
restricted by approvals. For detailed information, see the sensor’s
calibration tag.

Sensor-to-remote booster amplifier cable lengths

Remote booster amplifiers are shipped with:

• 16 feet (5 meters) of 9-wire cable for connection to the sensor’s
intrinsically safe junction box

• 16 feet (5 meters) of 2-wire cable for connection to the sensor’s
explosion-proof junction box (not available in all locations)

For longer cable lengths, up to 60 feet (20 meters), contact Micro
Motion.

Sensor-to-transmitter cable lengths

Maximum cable length between sensor and transmitter depends on the
cable type. See Table 3

.

Sensor-to-core processor cable length

Maximum distance between the sensor and the core processor is 60 feet
(20 meters). If you are using a remote booster amplifier with a junction
box, connecting to a remote core processor, the combined length of the
two 9-wire cables (sensor-to-booster amplifier and booster amplifier-to­core processor) must be 60 feet (20 meters) or less.

STEP 2. Orienting the sensor

The sensor will function properly in any orientation if the sensor tubes
remain filled with process fluid. Micro Motion recommends installing the
sensor according to the type of process fluid and the flow direction:

• Preferred orientations are shown in Figure 5.

• The sensor has a flow direction arrow (see Figure 1) to help you
configure the transmitter for flow direction. If possible, install the
sensor so that the flow direction arrow matches actual process flow.

Figure 5. Preferred orientations

Liquids

• Tubes down

• Horizontal pipeline

Gases

• Tubes up

• Horizontal pipeline

STEP 3. Mounting the sensor

Using the sensor to support piping can damage the
meter or cause measurement error.

Do not use flowmeter to support pipe.

Slurries

• Flag mount

• Vertical pipeline

CAUTION

Flow

Use your common practices to minimize torque and bending load on
process connections.

Figure 6 illustrates how to mount the D600 sensor.

If possible, install wiring with the conduit opening pointed down to
reduce the risk of condensation or excessive moisture.
