Rosemount 8712 / 8700 Series

STEP 1: PRE-INSTALLATION

Before installing the Rosemount 8712 Magnetic Flowmeter Transmitter, there are several pre-installation steps that should be completed to make the installation process easier:

•Identify the options and configurations that apply to your application

•Set the hardware switches if necessary

•Consider mechanical, electrical, and environmental requirements

Mechanical Considerations

The mounting site for the Rosemount 8712 transmitter should provide enough room for secure mounting, easy access to conduit ports, full opening of the transmitter covers, and easy readability of the LOI screen (see Figure 1).

The Rosemount 8712 is mounted separately from the sensor, it is not subject to limitations that might apply to the sensor.
