NOTE
Please ensure to use the attached connecting
fittings.
Ceramic linings with a diameter of 2.5, 5 or 10 mm are
connected using union joints.
Use the connecting fittings according to the table
below. Depending on whether the fitting is to be
welded to or screwed on to the piping.

(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 match the direction, please
never remodel by changing direction of the
terminal 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 Flow Converter.
(2) Connecting Process Piping
Weld or screw the connecting fittings to the process
piping.
IMPORTANT
• Please be sure to pass the connecting fittings
through the union joint nuts in advance. Then
connect the connecting fitting to the piping by
screwing or welding the connecting fitting to the
piping (see Figure 3.3.1).
• In case of weld joint type, please pay attention
the welding condition to avoid deforming piping
or making the stagnant portion of the fluid;
joint preparation, level defference in butt joint,
welding current.
(3) Positioning the Flow Tube
Install the magnetic flow tube on a mounting base and
position it so that the center axis of the flow tube is
aligned with that of the piping. Then mount the flow
tube to union joint nuts by screwing the nuts to the
connecting ports of the flow tube.
CAUTION
The ceramic pipe will be damaged if they are
tightened when they are not properly aligned.
