Installation Procedures
For dimensional drawing information refer to
“Dimensional Drawings” on page 93
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.
Housing Rotation
See
“Consider Housing Rotation” on page 36
Power Module Side of Electronics Housing
Mount the transmitter so the Power Module side is accessible. Clearance of 2.75-in. (70 mm) is
required for cover removal.
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 polymer
contacts polymer. Use Rosemount O-rings.
3.4.1
Mount the Transmitter
Mounting Brackets
Facilitate mounting transmitter to a 2-in. pipe, or to a panel. The B4 Bracket (SST) option is
standard for use with the Coplanar and In-Line flanges. “Coplanar Flange Mounting Configura-
tions” on
shows bracket dimensions and mounting configurations for the B4 option.
Options B1–B3 and B7–B9 are sturdy, epoxy/polyester-painted brackets designed for use with
the traditional flange. The B1–B3 brackets have carbon steel bolts, while the B7–B9 brackets
have stainless steel bolts. The BA and BC brackets and bolts are stainless steel. The B1/B7/BA
and B3/B9/BC style brackets support 2-inch pipe-mount installations, and the B2/B8 style
brackets support panel mounting.
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 caused by the
varied mounting position. To reset zero point, refer to
.
Position the antenna such that it is vertical, typically straight up (antenna may be pointed down
as well.)
