(4) Connecting to Pipe
Please pass bolts from pipe line side, not flow tube
side, and tighten the bolts according to Torque Values
in Table 3.3.9.
CAUTION
• Please be sure to tighten the bolts following
prescribed torque values. Please tighten the
flange bolts diagonally with the same torque
values, step by step up to the prescribed torque
value.
• Please completely cover the brackets and liners
with mortar.

Mounting Procedure for Sani-
tary Type
The sanitary type is mounted using IDF clamps.
(1) Mounting Direction
Please mount the Magnetic Flow Tube matching the
flow direction of the fluid to be measured with the
direction of the arrow mark on the flow tube.

IMPORTANT
If it is impossible to macth the direction, please
never remodel to change direction of the termi-
nal box. In case the measuring fluid flows
against the arrow direction, please refer to the
section "Reversing Flow Direction" in the Instruc-
tion Manual of AM11 Magnetic Converter.
(2) Welding of Mating Ferrule to Piping
IMPORTANT
Weld the attached ferrules to the piping. Please
pay attention to the welding condition to avoid
deforming piping or making the stagnant portion
of the fluid; joint preparation, level difference in
butt joint, welding current.
(3) Mounting Gasket
Mount the attached gasket so it fits into the groove on
the ferrule.
(4) Positioning Flow Tube
Position the flow tube between the mating ferrule.
(5) Tightening Clamp
in-Ibf
522 to 646
Mount the clamp so they cover the flow tube and
593 to 743
mating ferrule tapered part.
