3. INSTALLATION
WARNING
Installation of the magnetic owmeter must
be performed by expert engineer or skilled
personnel. No operator shall be permitted to
perform procedures relating to installation.
3.1 Piping Design Precautions
IMPORTANT
Design piping correctly, referring to the following
to prevent damage to owtubes and to assure
accurate measuring.
(1) Location
IMPORTANT
Install the owmeter in a location where it is
not exposed to direct sunlight. The minimum
ambient temperature is limited by the minimum
uid temperature of the owtube (the lining). For
more information, refer to Chapter 6 “OUTLINE”.
The owmeter may be used in an ambient
humidity where the relative humidity ranges from
0 to 100%. However, avoid long-term continuous
operation at relative humidity above 95%.
(2) Noise Avoidance
IMPORTANT
The owmeter should be installed away from
electrical motors, transformers, and other power
sources in order to avoid interference with
measurement.
(3) Required Lengths of Straight Runss
To maintain accurate measurement, see JIS B7554
“Electro Magnetic Flowmeters” which explains the
requirements for upstream piping conditions of
magnetic owmeters.
Based on JIS B7554 “Electro Magnetic Flowmeters”
and our piping condition test data, we recommend
the piping conditions as shown in the following
gures.
When installing two or more magnetic owmeters
on a single pipe, provide a run of at least 10D
between them.

Figure 3.1.1 Required Lengths of Straight Runs
*1: Do not install anything in the vicinity that may
interfere with the magnetic eld, induced signal
voltages, or ow velocity distributions of the
owmeter.
*2: A straight run may not be required on the
downstream side of the owmeter. However,
if a downstream valve or other tting causes
irregularity or deviation in ows, provide a
straight run of 2D to 3D on the downstream
side.
*3: The valves shall be mounted on the
downstream side so that deviated ows do not
occur in the owtube and to avoid startup from
an empty condition.
(4) Maintaining Stable Fluid Conductivity
IMPORTANT
Do not install the owmeter where uid
conductivity tends to become uneven. If
chemicals are fed near the upstream side of a
magnetic owmeter, they may affect the ow
rate’s indications. To avoid this situation, it is
recommended that the chemical feed ports be
located on the downstream side of the owmeter.
If it is unavoidable that chemicals must be fed on
the upstream side, provide a sufcient length of
straight run (approximately 50D) to ensure the
proper mixture of uids.

(5) Precautions for Use of Liquid Sealing
Compounds
IMPORTANT
Care must be taken in using liquid sealing
compounds on the piping, as it may have a
negative inuence on the ow indications by
owing out and covering the surfaces of an
electrode or grounding ring. In particular, care
must be taken if a liquid sealing compound is
used in the case of vertical piping.
(6) Service Area
Select locations where there is adequate space to
service installing, wiring, overhauling, etc
(7) Bypass Line
It is recommended to install a bypass line to facilitate
maintenance and zero adjustment.

(8) Supporting the Flowmeter
CAUTION
Do not secure the owmeter separately to
prevent the vibrations, shocks, and expansion
and contraction forces of the piping from
affecting it. Fix the pipeline or its anges rst,
then let them support the owmeter.
For vertical, mounting, make sure that the weight
of piping does not weigh on the owmeter.
To release the load from tightening the owmeter
to the pipeline, set a expansive pipe in the
downstream side.
(9) Mounting Positions
• Pipes must be fully lled with liquids.
IMPORTANT
It is essential that pipes remain fully lled at
all times, otherwise ow rate indications may
be affected and measurement errors may be
caused.
Piping shall be designed so as to maintain the
interior of the owtube lled with uids.
Vertical mounting is effective in such cases as
when uids tend to separate or solid matter may be
precipitated. When employing vertical mounting,
direct the uids from the bottom to the top to ensure
that the pipes remain fully lled.

• Avoid air bubbles.
IMPORTANT
If air bubbles enter a measurement pipe,
ow rate indications may be affected and
measurement errors may be caused.
In cases where uids contain air bubbles, piping must
be designed to prevent them from accumulating in
the measurement pipe of a owtube.
If a valve exists near the owmeter, try to mount the
owmeter on the valve’s upstream side in order to
prevent a possible reduction of pressure inside the
pipe, thereby avoiding the possibility of air bubbles.

WARNING
The magnetic owmeter is a heavy instrument.
Be careful that no damage is caused to
personnel through accidentally dropping it, or
by exerting excessive force on the magnetic
owmeter. When moving the magnetic
owmeter, always use a trolley, forklift, or crane
and have at least two people carry it.
3.2.1 General Precautions
(1) Precaution during Transportation
The magnetic owmeter is packed tightly. When
it is unpacked, pay attention to prevent damaging
the owmeter. To prevent accidents while it is being
transported to the installing location, transport it to
the site in its original packing.
CAUTION
When lifting the owtube, use the lifting rings
(eye bolts or eye plates) as in Figure 3.2.1.
Never lift it using a bar passed through the
owtube as this damages the liner severely.

(2) Avoiding Shocks from Impact
CAUTION
Care should be taken not to drop the owmeter
or expose it to excessive shock. In particular, be
careful not to subject the ange surface to shock.
This may lead to liner damage which will result in
inaccurate readings.
(3) Flange Protection Covers
IMPORTANT
Keep the protective covering (i.e. the corrugated
cardboard or other cushioning material) in place
over the ange except when mounting the
owmeter to the pipe.
(4) Terminal Box Cover
IMPORTANT
As it is possible that the insulation will
deteriorate, do not remove the wrapping of the
terminal box nor open the terminal box cover
until it is time to wire it.
(5) Long-term Non-use
IMPORTANT
It is not desirable to leave the owmeter unused
for a long term after installation. If this situation
is unavoidable, take care of the owmeter by
observing the following.
<3.INSTALLATION>
3-4
IM 01E25D11-01EN
• Conrmationofsealingconditionsforthe
owmeter
Conrm that the terminal box screw and wiring ports
are well sealed. Equip the conduit piping with drain
plugs or waterproof glands to prevent moisture or
water from penetrating into the owmeter through
the conduit.
• Regularinspections
Inspect the sealing conditions as mentioned above,
and the inside of the terminal box at least once a
year. Also, due to rain, etc. when it is suspected
that water may have penetrated into the inside
owmeter perform supplementary inspections.
3.2.2 FlowmeterPiping
CAUTION
Misaligned or slanted piping can lead to leakage
and damage to the anges.
(1) Correct any misaligned or slanted piping, and
any gaps that may exist between mounting
anges before installing the owmeter (refer to
Figure 3.2.2).
Slanted
F0308.ai
Misaligned
Figure3.2.2 SlantedandMisalignedFlowmeter
Piping
(2) Inside a newly installed pipeline, there may
be some foreign substances such as residue
from welding or wood chips. Remove them
by ushing the piping before mounting the
owmeter. This prevents the lining from
being damaged, as well as the occurrence
of erroneous measured signals resulting
from foreign substances passing through the
owtube during measurement.
3.3 MountingProcedures
CAUTION
When attaching optional grounding rings to
the owtube with lining material natural hard
rubber or uorocarbon PTFE, gaskets must be
placed between each grounding ring and the
owtube. Fluid leakage will happen without these
gaskets. These gaskets are to be supplied by
customer. Do not forget those gaskets also when
ordering and attaching the grounding rings later
additionally.
NOTE
The tightening torque value varies depending
on the type of lining and gasket as shown in the
tables in this section.
IMPORTANT
Use bolts and nuts in compliance with the ange
ratings. When choosing the gaskets, be sure to
choose sheet gaskets designed to t for ange
standard.
(1) MountingDirection
Mount the owmeter so that the ow direction of
the uid to be measured is in line with the direction
of the arrow mark on the owmeter. It may be
especially difcult to move large size owtubes after
bringing them into the pit. Check directions before
bringing.
IMPORTANT
If it is impossible to match the direction of
the arrow mark, the direction of the electrical
connection can be changed. Refer to Section 5.1
to do this properly.
In case the uid being measured ows against
the arrow direction, refer to the parameter J20:
FlowDirection in the user’s manual of the

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