Mounting the Enclosure

You can mount the flow computer either directly to a manifold on the pipeline or indirectly on a
two-inch pipe or pole.
Direct mount installations use either a traditional mounting kit or a coplanar mounting kit. Indirect
mount installations use an inline mounting kit.
2.7.1

Bolting Considerations

If the flow computer installation requires assembly of a process flange, a manifold, or flange
adapters, follow these assembly guidelines to ensure a tight seal for optimal performance
characteristics of the flow computer.
Installation
Unscrew the end cap turning it counter-clockwise until it comes off. Set it aside in a safe
location.

DANGER
Grasp the end cap (front or rear).
Carefully align the end cap threads with the threads of the enclosure.
Important
When replacing the rear end cap, ensure wires connecting to the terminal plate do not get
crimped or caught between the end cap threads and the enclosure.
Screw the end cap clockwise (eight full turns) until it is tightly sealed to the enclosure.
Replace the retaining clamp (if required). (See
Note
If you need more leverage place a long screwdriver or other appropriate tool across the two
notches in the end cap to act as a pry bar (see
Emerson FB1100 Flow Computer Instruction Manual
Section 2.6.1.)
