Size 150 to 200 mm (6 to 8 in.) is specied, hang the
grounding rings with their ange type printings outer side
of the magnetic owmeter.
Set the angle of both handles symmetrically to be top.
If there are any bolt-holes under the handles, turn the
grounding rings clockwise in order to locate handles
between bolt-holes. Center the grounding ring to the
center of the magnetic owmeter.
Size 250 to 400 mm (10 to 16 in.) is specied, hang the
grounding rings with their ange type printings outer side
of the magnetic owmeter.
Set the angle of both handles symmetrically to be 45
degree from top. If there are any bolt-holes under the
handles, turn the grounding rings clockwise in order to
locate handles between bolt-holes. Center the grounding
ring to the center of the magnetic owmeter.
Connect the wire from the grounding ring to the screw of
the magnetic owmeter’s ange and x the wire by the
screw. This procedure must be done for the both sides of
the magnetic owmeter.

• Installation: PTFE/Natural hard rubber lining type
and Metal pipe
When a magnetic owmeter with PTFE or natural
hard rubber lining is installed to metal pipe without
lining, the installation method without grounding ring
is recommended.
Size 25 to 125 mm (1 to 5 in.), PTFE lining,
and without grounding ring are specied, it is
recommended to use no gasket between the pipe
and the sensor. With grounding wire (supplied by
customer), connect between the pipe and the sensor
ange, or between the transmitter and the grounding
terminal of terminal box. For grounding in detail, read
Subsection 4.4.3.
Size 150 to 400 mm (6 to 16 in.), PTFE or natural
hard rubber lining, and without grounding ring are
specied, use the gasket A (customer pipe side) for
connection with customer pipes. With grounding wire
(supplied by customer), connect between the pipe
and the sensor ange, or between the transmitter and
the grounding terminal of terminal box. For grounding
in detail, read Subsection 4.4.3.
For gasket A (customer pipe side), use non-asbestos
joint sheet gasket, PTFE-sheathed non-asbestos joint
sheet gasket or gasket with the equivalent hardness.
For gasket B (sensor side), use non-asbestos joint
sheet gasket, PTFE-sheathed non-asbestos joint
sheet gasket or gasket with the equivalent hardness.
It is recommended to use gasket with same hardness
for gasket A and B.
