Definitions

The term MVD

™

transmitter refers to the following transmitter models:

• Models 1500, 1700, 2500, and 2700

• Models 3500 and 3700 with sensor interface code 5 or 6

European installations

This Micro Motion product complies with all applicable European directives when properly installed in
accordance with the instructions in this manual. Refer to the EC declaration of conformity for directives that
apply to this product.

The EC declaration of conformity, with all applicable European directives, and the complete ATEX
Installation Drawings and Instructions are available on the internet at www.micromotion.com/atex or
through your local Micro Motion support center.

Information affixed to equipment that complies with the Pressure Equipment Directive can be found on the
internet at www.micromotion.com/documentation.

Purge plugs

If you remove a purge plug from the sensor case, it will be necessary to repurge the case. Refer to Case
purging procedure on page 14 for more information about repurging the sensor case.

Removing a purge plug compromises the secondary containment of the sensor and could expose the
user to process fluid. The sensor case may contain process fluid. Take all necessary precautions when
removing the purge plug

Installation options

The T-Series sensor makes up one part of a Coriolis flowmeter. The other part is a transmitter. T-Series
sensors are available with the following electronics interfaces:

• An integral core processor for connecting to a 4-wire remotely mounted transmitter or to a
user-supplied remote host (see Figure 1).

• An integrally mounted Model 1700 or 2700 transmitter (see Figure 2).

• A 9-wire junction box for connecting to a remotely mounted transmitter or a remotely mounted core
processor (see Figure 3).

Step 1 Determining a Location

Choose a location for the sensor based on the requirements described in this section. The following general
guidelines can help you select an appropriate location for the sensor.

Full flow tubes

For optimal performance, the sensor tubes should remain full of process fluid.

Hazardous area installations

Make sure the hazardous area specified on the sensor approval tag is suitable for the environment in which the
sensor is installed. (See Figures 1–3.) For installation in an area that requires intrinsic safety, refer to the
appropriate Micro Motion approval documentation, shipped with the sensor or available from the Micro
Motion web site at www.micromotion.com.

Improper installation in a hazardous area can cause an explosion. When installing in a hazardous area,
refer to Micro Motion approvals instructions, shipped with the product 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.

Environmental limits

The ambient and process temperature limits of the sensor are shown in Figure 4.
