Quick Installation and Startup
2.10.2 Alignment
1. On 1.5 through 8-inch (40 through 200 mm) line sizes, Rosemount requires installing
the alignment spacers to ensure proper centering of the wafer sensor between the
process flanges.
2. Insert studs for the bottom side of the sensor between the pipe flanges and center the
alignment spacer in the middle of the stud. See Figure 2-9 for the bolt hole locations
recommended for the spacers provided. Stud specifications are listed in Table 2-7.
3. Place the sensor between the flanges. Make sure the alignment spacers are properly
centered on the studs. For vertical flow installations slide the O-ring over the stud to
keep the spacer in place. See Figure 2-9. Ensure the spacers match the flange size and
class rating for the process flanges. See Table 2-8.
4. Insert the remaining studs, washers, and nuts.
5. Tighten to the torque specifications shown in Table 2-9. Do not over-tighten the bolts
or the liner may be damaged.
