Installing the Transmitter

2.1Overview

This chapter describes how to install Micro Motion Model 1700 and 2700 transmitters. The following general steps are required:

•Determine the location of the transmitter and other flowmeter components (see Section 2.3)

•Mount the transmitter (see Section 2.4)

•Mount the core processor, if required (see Section 2.5)

•Ground the flowmeter components (see Section 2.6)

•Supply power to the flowmeter (see Section 2.7)

•Rotate the display, if desired and the transmitter has a display (see Section 2.8)

2.2Installation architecture

Your flowmeter installation will match one of the architectures shown in Figure 2-1.Mounting, sensor wiring, and grounding requirements depend on this architecture. Your installation type should be consistent with the installation type specified in your transmitter model number (see Section 1.4).
