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).
