2.5.2 Mount the transmitter
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 accessibility 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
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 on the unused side of the conduit opening.
Circuit side of electronics housing
Provide 0.75-in. (19 mm) of clearance for units without an LCD display.
Provide 3-in. (76 mm) of clearance for units installed with LCD.
Cover installation
Always ensure a proper seal by installing the electronics housing covers so that metal
contacts metal. Use Rosemount O-rings.
Mounting brackets
Rosemount 2051 Transmitters may be panel-mounted or pipe-mounted through an
optional mounting bracket. Refer to
