1. Whenever the flange or adapters are removed, visually inspect the O-rings.
2. Replace the O-rings if there are any signs of damage, such as nicks or cuts.
3. If the O-rings are replaced, re-torque the flange bolts and alignment screws after installation
to compensate for seating of the O-rings.
2.7.3 Direct Mount
Direct mount installations use either a traditional mounting kit or a coplanar mounting kit. Mount
the flow computer directly to the natural gas pipeline only if the pipeline includes a process
manifold.
