Description of Change
The Maximum Working Pressure Rating and the
Overpressure Rating has been enhanced for all
models included in this addendum except for the
draft range transmitter.
For more information, refer to Table 6 in this
Addendum.
In Step 5, do not use the torque specification of 47.5
to 54 N∙m (35 to 40 lb-ft).
Instead, torque Flange Adapter bolts evenly to
47,5 N·m +/- 2,4 N·m (35 Lb-Ft +/- 1.8 Lb-Ft).
In Step 8, do not use specifications for head bolt
torque given in Table 54.
Instead, torque head bolts/nuts to the specifications
given in Table 2 of this addendum.
In Step 9, the reference to Table 48 for applying
torque to head bolts/nuts should be as given in
Table 2 of this addendum.
Figure 57 illustrates the replacement parts available
for the previous design of meter body and process
heads, and Table 71 provides part numbers and
descriptions for the parts called out in Figure 57.
For the newly designed meter body and process
heads, use Figure 1 of this addendum to locate
replacement parts, and use
addendum for part numbers and descriptions.
For applicability of parts, refer to the appropriate
