Wafer Sensors

Gaskets

The sensor requires a gasket at each of its connections to adjacent devices or piping. The 
gasket material selected must be compatible with the process fluid and operating conditions. 
Metallic or spiral-wound gaskets can damage the liner. Gaskets are required on each side of 
a grounding ring. See Figure  below.

Alignment 

1. On 1.5 through 8-inch (40 through 200 mm) line sizes. Rosemount strongly recommends 

installing the alignment spacers provided to insure proper centering of the wafer sensor 
between the process flanges. Sensor sizes of 0.15, 0.30, 0.5 and 1 in. (4 through 25 
mm), do not require alignment spacers.

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 8 for the bolt hole locations 
recommended for the spacers provided. Stud specifications are listed in Table 3. 

3. Place the sensor between the flanges. Make sure that 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 8. To ensure the spacers match the flange 
size and class rating for the process flanges see Table 4.

4. Insert the remaining studs, washers, and nuts.

5. Tighten to the torque specifications shown in Table 5. Do not overtighten the bolts or the 

liner may be damaged.

Table 3. Stud Specifications

NOTE

Sensor sizes of 0.15, 0.30, and 0.5 in. mount between AMSE 1/2-inch flanges. Using carbon 
steel bolts on sensor sizes of 0.15, 0.30, 0.5 and 1 in. (15 and 25 mm), rather than the 
required stainless steel bolts, will degrade the flow sensor measurement.
