Installation procedures
2.8.1
Mount the transmitter
For dimensional drawing information refer to
Appendix A: Specifications and reference data
.
Process flange orientation
Mount the process flanges with sufficient clearance for process connections. For safety reasons,
place the drain/vent valves so the process fluid is directed away from possible human contact
when the vents are used. In addition, consider the need for a testing or calibration input.
Note
Most transmitters are calibrated in the horizontal position. Mounting the transmitter in any
other position will shift the zero point to the equivalent amount of liquid head pressure caused
by the varied mounting position. To reset zero point, refer to
.
Housing rotation
See
.
Terminal side of electronics housing
Mount the transmitter so the terminal side is accessible. Clearance of 0.75 in. (19 mm) is
required for cover removal. Use a conduit plug in the unused conduit opening.
Circuit side of electronics housing
Provide 0.75 in. (19 mm) of clearance for units with out an LCD display. Three inches of
clearance is required for cover removal if a meter is installed.
Cover installation
Always ensure a proper seal by installing the electronics housing cover(s) so that metal contacts
metal. Use Rosemount O-rings.
Conduit entry threads
For NEMA 4X, IP66, and IP68 requirements, use thread seal (PTFE) tape or paste on male threads
to provide a watertight seal.
Mounting brackets
Rosemount 3051 Transmitters may be panel-mounted or pipe-mounted through an optional
