6.5 Installation Procedure
Install the meter body in the following manner:
(1) Install adjust rings on the meter periphery at both ends. ASME 150 and JP1 150 meters 25 millimeters in
nominal diameter do not require adjust rings.
(2) Fitting flange gaskets at both ends, sandwich the meter body between flanges.
CAUTION: Exercise care not to allow flange gaskets to protrude into the interior of
the meter (pipe), or meter accuracy will suffer.

(3) Pass the connecting bolts through their openings
and tighten up the bolts. Individual bolts are now
closely in contact with the adjust rings and the
inner wall of flange bolt holes, forcing the meter
body to be concentric to the pipe.

CAUTION: Unless adjust rings are installed in place, flowmeter-to-pipe
misalignment will result in loss of meter accuracy. Be sure, for this
reason, to fit the adjust rings in place before bolting the flanges.
