Flow Tube Piping - YOKOGAWA ADMAG AM100D User Manual

(2) Precaution for Shock
CAUTION
Care should be taken not to drop the flow tube
or subject it to excessive shock. This may lead
to liner damage which will cause inaccurate
readings.
(3) Flange Protection Covers
IMPORTANT
Please keep the protection cover (ex. corrugated
paper or anything possible to protect) attached
with flange except when mounting to the pipe.
(4) Terminal Box Cover
IMPORTANT
Please never leave the terminal box cover open
until wiring to prevent insulation deterioration.
(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.

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.
