Micro Motion®Model D and DT Sensors Instruction Manual 1

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 user-

supplied 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.

Before You Begin continued

DT065, DT100, and DT150 sensors

The installation process Installing your new sensor involves five steps:

Step 1. Location

Determining the proper location for the sensor, taking into account

hazardous areas, process piping, transmitter location, and valves. See

page 9.

Step 2. Orientation

Determining the desired orientation for the sensor in the process

pipeline. See page 13.

Step 3. Mounting

Installing the sensor in the pipeline. See page 17.

Step 4. Wiring

Connecting the flowmeter cable to the sensor and transmitter. See

page 19.

Step 5. Startup

Requirements for flowmeter startup. See page 39.
