Mounting Procedure for Sani-
tary Type
The sanitary type is mounted using ISO(IDF) clamps.
(1) Mounting Direction
Please mount the Magnetic Flowmeter matching the
flow direction of the fluid to be measured with the
direction of the arrow mark on the flowmeter.
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 6.3.6 or 7.2.8 Reversing Flow Direction.
(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 Flowmeter
Position the flowmeter between the mating ferrule.
(5) Tightening Clamp
Mount the clamp so they cover the flowmeter and
mating ferrule tapered part.

4.4 Wiring Precautions
CAUTION
Please confirm that all conncetions are correct
before applying power to the instrument.
Improper wiring may damage the flowmeter.
The external signal wirings are connected into the
terminal inside the converter. Please connect to each
terminal (Please refer to Figure 4.4.1) by taking off a
cover backside the converter.

Protective Grounding
CAUTION
Please be sure to connect protective grounding
of ADMAG AE with cable of 2mm
2
or larger
cross section in order to avoid the electrical
shock to the operators and maintenance engi-
neers and prevent the influence of external
noise. And further connect the grounding wire to
the
mark (100
Ω
or less).
