Flange Bolts

Wafer sensors require threaded studs. See Figure7 for torque sequence . Always check for
leaks at the flanges after tightening the flange bolts. All sensors require a second torquing
24 hours after initial flange bolt tightening.
Sanitary 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.
Gaskets are supplied between the IDF fitting and the process connection fitting, such as a
Tri-Clamp fitting, on all Rosemount 8721 Sanitary sensors except when the process
connection fittings are not supplied and the only connection type is an IDF fitting.

Alignment and Bolting

Standard plant practices should be followed when installing a magmeter with sanitary
fittings. Unique torque values and bolting techniques are not required.
