3. INSTALLATION
CAUTION
Be sure to lock the cover with the special screw
using the Hexagonal Wrench attached after
tightening the terminal box cover.
(5) Long-term Non-use
IMPORTANT
It is not preferable to leave the flow tube for long
term non-use after installation.
In case the flow tube is compelled to do that,
please take care of the flow tube by the follow-
ings.
• Confirmation of Sealing Condition for the Flow
Tube
Please confirm the sealing conditions of the terminal
box screw and wiring ports.
In case of the Conduit Piping, please provide the
drain plugs or waterproof glands to it to prevent that
moisture or water penetrates into the flow tube
through the conduit.
• Regular Inspections
Please inspect the sealing condition (as above
mentioned) and inside of the terminal box. And
when it is suspect that water penetration into the
inside flow tube (ex. rain fall), please inspect when
it happened.
3.2.2
Flow Tube Piping
CAUTION
Mis-aligned or slanted piping can lead to leakage
and damage to flanges.
• Please correct mis-alignment or slanted piping and
improper distance between mounting flanges before
install the flow tube. (Please refer to Figure 3.2.2)
• Inside a pipeline which is newly installed, some
foreign substances (such as welding scrap or wood
chips) may exist. Please remove them by flushing
piping before mounting the flow tube.

3.3 Mounting
3.3.1
Nominal Diameter 15mm (0.5˝)
to 40mm (1.5˝) Wafer Type
IMPORTANT
Please use appropriate bolts and nuts according
to process connection. In case stud type of
through bolts are used, be sure outside diameter
of a shank is smaller than a thread ridge’s one.
Please use compressed non-asbestos fiber
gasket, PTFE gasket or the gasket which has
equal elasticity. In case of optional code/FRG,
please use rubber gasket or others which has
equal elasticity. Be sure the inner diameter of
the gasket does not protrude to inner piping.
(Refer to Table 3.3.6)
(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 SE14 Magnetic Flow Converter.
(2) Mounting Centering Devices
To keep concentricity of the Flow Tube with pipes,
please mount centering devices on the Mini-Flanges of
the Flow Tube. Please give attention to the nominal
diameter and flange rating of the centering devices.
