(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.
Block valve
(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 or more) to ensure the proper
mixture of uids.

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 sensor.
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.

IMPORTANT
If electrodes are perpendicular to the ground, air
bubbles near the top or precipitates at the bottom may
cause measurement errors. Ensure that the terminal
box of a remote sensor and transmitter of an integral
owmeter are mounted above the piping to prevent
water from entering them.

Installation
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 sensor 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.

3.2 Handling Precautions
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
and have at least two people carry it.
NOTE
This section describes the remote sensor as an
example. The same attention must be paid to the
integral owmeter.
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.
(2) Avoid 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 lining 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 open the terminal box cover until it is time to wire it.
CAUTION
When lifting the magnetic owmeter, use the lifting rings
(eye bolts or eye plates) as in Figure 3.2.1.
Never lift it using a bar passed through the magnetic
owmeter as this damages the liner severely.
90 degrees or less
Eye bolt Eye plate
Figure 3.2.1 Lifting Flowmeter
90 degrees or less
(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.
Conrmation of sealing conditions for the
owmeter
Conrm that the terminal box screw and electrical
connections 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.
Regular inspections
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 of the owmeter, perform
supplementary inspections.

3.2.2 Flowmeter Piping
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 (see Figure 3.2.2).
Slanted
Figure 3.2.2 Slanted and Misaligned Flowmeter 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 sensor during
measurement.
Misaligned
3.3 Integral Flowmeter and Remote Sensor Installation
WARNING
• All gaskets used for piping of Magnetic Flowmeters
should be prepared by customers except in some
cases.
With the option of grounding ring, if the lining is
natural hard rubber or PTFE, gaskets must be
placed between each the grounding ring and the
sensor to avoid uid leakage. These gaskets are
to be supplied by customer. Do not forget those
gaskets also when ordering and attaching the
grounding rings later additionally.
• Use the gasket of the equivalent hardness for
gasket (customer pipe) and gasket (sensor).
NOTE
• The tightening torque of gaskets varies by the
type and external dimensions of the lining and the
gasket. The tightening torque values should be
decided by referring to Table 3.3.1.
• For uids capable of potentially permeating PTFE
linings (such as nitric acid, hydrouoric acid, or
sodium hydrate at high temperatures), do not use
the PTFE lining type.
3
Installation
NOTE
• The PTFE lining has a structure adhering PTFE to
the metal inner face of the sensor. When tightening
bolts and nuts to install to the piping, be careful not
to bring unequal stress or torque to the PTFE lining.
• For the PTFE lining, it is recommendedo be installed
with grounding rings, or to be installed with short
pipes at upstream and downstream sides.
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) Mounting Direction
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 sensors 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. Read Section 3.5.
In case the uid being measured ows against the
arrow direction, change the value from “Forward” to
“Reverse” at the parameter “Flow direct”. Read the
user’s manual of the applicable communication type
(for AXW/AXW4A) or the hardware/software edition
(for AXFA11) as listed in Table 1.1.
