The Rosemount 3051SMV Transmitter is attached to the process connection flange by four bolts and
two alignment cap screws.

2. Remove the four bolts and separate the transmitter from the process connection, but leave the
process connection flange in place and ready for re-installation.
Note
If installation uses a manifold, see “Manifold operation” on page 32 .
3. Inspect the sensor module PTFE O-rings. If the O-rings are undamaged, they may be reused. Emerson
recommends reusing O-rings if possible. If the O-rings show any signs of damage, such as nicks or
cuts, they should be replaced (part number 03151-9042-0001 for glass-filled PTFE and part number
03151-9042-0002 for graphite-filled PTFE).
Note
If replacing the O-rings, be careful not to scratch or deface the O-ring grooves or the surface of the
isolating diaphragm when removing the damaged O-rings.
4. Install the process flange on the sensor module process connection. To hold the process flange in
place, install the two alignment cap screws finger tight (these screws are not pressure retaining). Do
not overtighten; this will affect module-to-flange alignment.
5. Install the appropriate flange bolts.
a. If the installation requires a

–18 NPT connection(s), use four 1.75-in. flange bolts. Finger
tighten the bolts. Go to Step d.
