3.4Installation procedures

For dimensional drawing information refer to Appendix A: Specifications and Reference Data on page 89.

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 “Sensor Trim” on page 68.

Consider housing rotation

The electronics housing can be rotated up to 180 degrees in either direction to improve field access, or to better view the optional LCD Display. To rotate the housing, perform the following procedure:

1. Loosen the housing rotation set screw using a 5 -in. hex wrench.

Power Module side of electronics housing

Mount the transmitter so the Power Module side is accessible. Clearance of 3.5-in. (89 mm) is required for cover and Power Module removal.

Circuit side of electronics housing

Provide 1.75 in. (45 mm) of clearance for units without an LCD display. Three inches of clearance is required for cover removal if a meter is installed.
