The threaded mounting studs and nuts supplied in
the meter installation kit should be well lubricated
before use. When the meter has been installed in
the pipeline, tighten the nuts in even increments
around the flange surface as described in Figure
2-6. It is recommended that an open end wrench
with an handle no greater than 8 inches be used for
tightening the nuts; i.e., torque should be limited to
that which will produce a positive seal without dam-
age to the face of the meter spool. Refer to Table
2-1 for recommended bolt torque.
Should it become necessary or advantageous to
replace an existing magnetic flowmeter of a greater
length with a Model 10D1477 CK-MAG, a flanged
spool piece is available from for ANSI Class 150
flanges in 1" - 4" sizes. The length of the spool is
selected so that the laying length of the CK-MAG
plus the spool piece will be the same as that of the
meter it is replacing. Therefore, existing piping does
not have to be altered. Specify the model number
and size of the meter being replaced to facilitate
spool piece selection.

NOTE
The recommended bolt torque limits are based on the use of
gaskets supplied by the manufacturer. Using other than the gaskets
supplied by the manufacturer will void the warranty.
