This is available for the models with process
connection JIS F12 (JIS 75M) in sizes 1100 mm
(44 in.) and above. Only gaskets A are to be
supplied by customer. Use soft rubber gasket,
PTFE-sheathed non-asbestos gasket, or its
equivalent in hardness.
The grounding rings are installed and locked
onto the magnetic flowmeter with gaskets B
when shipped from factory.
Mounting Procedure (no Grounding Rings):
Connect the magnetic flowmeter’s flange and the
customer’s pipe which contact process fluid by
some wire supplied by customer.
Mounting Procedure (with optional Grounding
Rings GR1 for sizes up to 1000 mm (40 in.)):
1. Handles of the grounding ring have some holes
which correspond to outer diameter of each
flange type. There are printings near each hole.
The printings show types of flange. See the
table below.

2. Confirm the centering pin is fixed to the hole
corresponding to flange or fix the centering pin
to the correct hole.
3. Hang the grounding rings with their flange type
printings outer side of the magnetic flowmeter.
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 flowmeter.
4. Connect the wire from the grounding ring to the
screw of the magnetic flowmeter’s flange and
fix the wire by the nut. This procedure (item
1 to 4) must be done for the both sides of the
magnetic flowmeter.
5. Install the magnetic flowmeter into the
customer’s pipe with the gaskets A.

Mounting Procedure with Grounding Rings
GR1 for sizes up to 1000 mm
(40 in.)
Mounting Procedure (with optional Grounding
Rings GR1 for sizes 1100mm (44 in.)) and above :
1. The grounding ring is temporarily fixed onto
the magnetic flowmeter by four bolts. Hang the
grounding ring up using a crane or a hoist so
that it would not fall down from the magnetic
flowmeter while setting the gasket B.
2. Unfasten the bolts and remove the grounding
ring off from the magnetic flowmeter.
3. Place the gasket B to the magnetic flowmeter.
Cut out holes on the gasket B if necessary, so
that the bolts can go through. Fix the grounding
ring to the magnetic flowmeter by the four bolts
again.
4. Connect the wire from the grounding ring to the
screw at the flange and fix the wire by the nut.
This procedure (item 1 to 4) must be done for
the both sides of the magnetic flowmeter.
