WARNING
Before removing the unit, make sure that there is no residual liquid or pressure
inside the piping and the detector to avoid personal injury or damage to the unit.
CAUTION
The detector must be grounded (grounding reference is <100 W) to avoid output
uctuation, zero point instability or output drift.
CAUTION
The installation location must satisfy the following conditions to avoid output
errors and uctuations.
At the installation location:
• The electrical conductivity of the uid to be measured must match the stated
specication (specs vary according to the converter used) and be more or less
constant.
• The uid to be measured must be electrochemically homogenized. For example,
if two uids are mixed at an upstream point, the device should be installed at
a point so that the two uids can be evenly mixed by the time they reach the
measuring point.
• The distribution of additive matter, if any, must be nearly uniform.
CAUTION
To avoid measurement problems, do not use the MagneW
FLEX+/PLUS+ to measure
the following uids, even if their electrical conductivity, temperature and pressure
fall within the specications.
• Fluids that have sucient electrical conductivity at high temperatures but do not
satisfy the conductance requirements at room temperature (about 20°C (68°F)).
For example, fatty acids or soap.
• Certain uids that contain surfectants. For example, rinses, shampoos, CWM.
• Conductive adherents. For example, deposition of rosin or conductive material.
• Insulating adherents. For example, oil, kaolinite, kaolin, or calcium stearate.
CAUTION
This model MGG/MGS detector can only be connected to Azbil Corporation's
model MGG10C/14C converter.
No other types of converters can be used with the device.

CAUTION
If the pipe is not lled, output errors will occur.
CAUTION
Do not rotate the unit more than 180° (one half rotation). Any further rotation can
disconnect wiring.
After removing the screws, do not pull on the terminal box. You can break the
lead wire.
When you move the terminal box, make sure the O-ring remains in the groove to
insure an air-tight seal when the unit is reassembled.
CAUTION
Before installing the detector, make sure any foreign matter is ushed from
the interior passage of the detector. Residual foreign matter could cause output
uctuations.
Do not touch the electrodes or allow oil or fat to come into contact with them to
avoid output uctuations.
Align the direction mark on the detector in the direction of the liquid ow.
Misalignment can result in a negative output.
CAUTION
The correct fastening torque must be used to prevent leakage. To avoid damage to
the detector, do not exceed the listed fastening torque.
CAUTION
Before installing the detector, make sure that the pipe is exactly straight and
centered. Any irregularity could cause leakage or other hazards.
CAUTION
Never attempt to force the detector between two anges if the space is too narrow.
It can damage the detector.
CAUTION
Make certain the bore diameters of the pipe and the detector are exactly the same
and install the detector so that the gasket does not protrude into the internal bore
of the pipe, as this could result in leakage or other hazards.

CAUTION
Tighten each bolt a little at a time and apply uniform pressure to all the bolts.
If leakage continues after tightening the bolts, make sure that the pipe is not o
center, then continue to tighten each bolt a little at a time.
CAUTION
Using a gasket with too small a diameter can aect the ow velocity distribution,
resulting in inaccurate measurement.
Using a gasket with too large a diameter can cause leakage. Also, any solid
substance in the uid to be measured could accumulate between the gasket and the
ange, resulting in inaccurate measurement.
CAUTION
The necessary materials and the installation method vary according to the material
of the ring and that of the pipe on which the detector is to be installed. Select the
appropriate method of installation from the following table after conrming the
specications of the detector to be installed and the conditions of installation.
Improper installation can result in leakage or damage to the pipe anges.
CAUTION
The use of anything other than the PTFE gaskets provided can result in leakage.
The use of rubber gaskets is not recommended and can cause leakage.
CAUTION
The use of rubber gaskets and a lower fastening torque is not recommended and
can cause insucient surface pressure between the lining and the grounding ring,
resulting in leakage.
CAUTION
Insucient grounding can cause output uctuations, instability of the zero point,
or output drift. Secure single point grounding with a grounding resistance of 100
W or less is recommended.
Do not ground a welder to the detector to avoid damaging the detector.

1.1 : Principle of operation
The owmeter consists of two parts: a detector which is mounted in the pipeline and
through which the measured liquid ows, and a converter which may be mounted
either integral with the detector or separately. The converter conditions and outputs
the electrical signal from the detector or separately. The converter conditions and
outputs the electrical signal from the detector.
The owmeter works based on the principle of Faraday’s law of electromagnetic
induction, which states that if an electrical conductor, in this case the measured
conductive liquid, passes through a magnetic eld a small electromotive force (EMF)
is induced perpendicular to the eld and ow (refer to Figure 1-1).
Faraday’s law:
E = k BDV when
E = Induced voltage (EMF)
B = Strength of the magnetic eld
D = Conductor width (electrode spacing)
V = Velocity of the conductor
k = Correction factor
This induced EMF is proportional to the average ow rate and is detected by
two electrodes (E
converter.
The only variable in this application of Faraday’s law is the ow rate (V) of the
conductive measured liquid, because eld strength (B), is controlled constant and
electrode spacing (D) is xed.
Therefore, the output electromotive force is directly proportional to liquid ow rate,
resulting in the linear output of a magnetic owmeter.

Install the unit in a location with an ambient temperature of -30 to +80°C (-22 to +
176°F) and a relative humidity of 5% to 100%. Failing to meet these requirements
could cause damage to the device or cause output errors.
Install the unit away from high-current power lines, motors and transformers to
prevent damage from electromagnetic induction. Failing to meet this requirement
could cause output errors.
Do not install the unit in a location subject to severe vibration or a highly
corrosive atmosphere. Failing to meet this requirement could break the neck of the
detector or cause other damage.
Install the unit as far from direct sunlight as possible to avoid output errors.
CAUTION
The installation location must satisfy the following conditions to avoid output
errors and uctuations.
At the installation location:
• The electrical conductivity of the uid to be measured must match the stated
specication (specs vary according to the converter used) and be more or less
constant.
• The uid to be measured must be electrochemically homogenized. For example,
if two uids are mixed at an upstream point, the device should be installed at
a point so that the two uids can be evenly mixed by the time they reach the
measuring point.
• The distribution of additive matter, if any, must be nearly uniform.
CAUTION
To avoid measurement problems, do not use the MagneW
the following uids, even if their electrical conductivity, temperature and pressure
fall within the specications.
Fluids that have sucient electrical conductivity at high temperatures but do not
satisfy the conductance requirements at room temperature (about 20°C (68°F)).
For example, fatty acids or soap.
• Certain uids that contain surfectants. For example, rinses, shampoos, CWM.
• Conductive adherents. For example, deposition of rosin or conductive material.
• Insulating adherents. For example, oil, kaolinite, kaolin, or calcium stearate.

2.3.2: Changing the position of the terminal box
In some locations, the direction of the terminal box may be unsuitable if the detector
is installed as it is shipped. In this case, the terminal box can be repositioned before
installation.
After selecting an installation site, adjust the direction of the terminal box using the
method described below.
To change the position of the terminal box:
(1) Using an M5 wrench, remove the four screws securing the terminal box to the
detector.
(2) Holding the detector, rotate the terminal box horizontally to the required position.
CAUTION
Do not rotate the terminal box more than 180° (one half rotation). Any further
rotation can disconnect wiring.
After removing the screws, do not pull on the terminal box. The lead wire can be broken.
When you move the terminal box, make sure the O-ring remains in the groove to
insure an air-tight seal when the unit is reassembled.
(3) Using a hex wrench, retighten the four screws.

2.4.3: Necessary parts
You will need the following parts to install a wafer detector:
• Centering nuts (four supplied)
• Connecting bolts and nuts (available separately)
• Gaskets: Required when using grounding rings made of SUS material. Not
required when using grounding rings made of hastelloy, titanium, tantalum, or
platinum.
• Protective Plate: Required when connecting the detector to polyvinyl chloride
(PVC) piping.
Centering nuts
The centering nuts create the exact alignment of the pipe and detector. These nuts
are positioned on through-bolts and the detector is set on top of the nuts to properly
position it against the anges.
The position of the centering nuts depends on the direction in which the detector is
installed. For horizontal centering of the detector, position two centering nuts against
each ange. For vertical centering of the detector, position the four centering nuts on
the bottom ange. The following gures show horizontal and vertical centering nut
positions.

Gaskets
Gaskets are supplied with the grounding ring, except when it is made of SUS
material. If you are using SUS material, you must provide the gaskets. Azbil
Corporation recommends joint sheet or polytetraouroethylene (PTFE) gasket
material. For the inner (bore) diameters of the gaskets, see the following table.
Rubber gaskets are not recommended.
CAUTION
Using a gasket with too small a diameter can aect the ow velocity distribution,
resulting in inaccurate measurement.
Using a gasket with too large a diameter can cause leakage. Also, any solid
substance in the uid to be measured could accumulate between the gasket and the
ange, resulting in inaccurate measurement.

CAUTION
Before installing the detector, make sure any foreign matter is ushed from
the interior passage of the detector. Residual foreign matter could cause output
uctuations.
Do not touch the electrodes or allow oil or fat to come into contact with them to
avoid output uctuations.
Align the direction mark on the detector in the direction of the liquid ow.
Misalignment can result in a negative output.

(The liquid could leak because of the
small area of contact with the gasket.)
Figure 2-22 Flange Shapes
CAUTION
Never attempt to force the detector between two anges if the space is too narrow.
It can damage the detector.
Figure 2-23 Unacceptable Placement of Detector Between Flanges
CAUTION
Make certain the bore diameters of the pipe and the detector are exactly the same
and install the detector so that the gasket does not protrude into the inner bore of
the pipe, as this could result in leakage or other hazards.
CAUTION
Tighten each bolt a little at a time and apply uniform pressure to all the bolts.
If leakage continues after tightening the bolts, make sure that the pipe is not o
center, then continue to tighten each bolt a little at a time.

2.5.2: Necessary parts
You will need the following parts to in stall the detector:
• Connecting bolts and nuts (available separately)
• Gaskets: Required when using grounding rings made of SUS material. Not
required when using grounding rings made of other materials.
• Protective Plate: Required when connecting the detector to polyvinyl chloride
(PVC) piping.
Gaskets
Gaskets are supplied with the grounding ring, except when it is made of SUS
material. If you are using SUS material, you must provide the gaskets. Azbil
Corporation recommends joint sheet or polytetraouroethylene (PTFE) gasket
material. For the inner diameters of the gaskets, see the following table. Rubber
gaskets are not recommended.
CAUTION
Using a gasket with too small a diameter can aect the ow velocity distribution,
resulting in inaccurate measurement.
Using a gasket with too large a diameter can cause leakage. Also, any solid
substance in the uid to be measured could accumulate between the gasket and the
ange, resulting in inaccurate measurement.

2.5.3: Selecting an installation method
To select an installation method you must determine the following:
• Mounting pipe material (metal or PVC)
• Grounding ring material (SUS or non-SUS)
• Need for a protective plate
• Use of rubber gaskets
CAUTION
The necessary materials and the installation method vary according to the material
of the ring and that of the pipe on which the detector is to be installed. Select the
appropriate method of installation from the following table after conrming the
specications of the detector to be installed and the conditions of installation.
Improper installation can result in leakage or damage to the pipe anges.

Direction of installation
Match the ow direction of the uid to be measured to that of the ow direction
mark on the electromagnetic owmeter. If they cannot be matched, the direction can
be changed on the terminal box or the converter. Refer to the section “Direction of
terminal box / converter”.
Position of the detector
Position the detector so that the center of the pipe aligns with that of the measuring
pipe of the electromagnetic owmeter. Be sure to fasten the electromagnetic
owmeter on a stand.
Pipe connection
For union assembly, mount the union joint nuts (supplied by the customer) on
the process pipe. Connect the pipe by screwing it into the connection hole of the
electromagnetic owmeter using the union joint nuts. For hose assembly, screw in the
hose, and fasten it with a fastening band, etc. (supplied by the customer).
Nut tightening (union assembly)
Use a torque wrench to tighten the union joint nuts. Do not tighten them fully to the
specied fastening torque one at a time. Instead, tighten the upstream and downstream
joint nuts alternately little by little over three or four turns. For the fastening torque,
see Table 2-9.

(6) Other machinery or equipment equivalent to those set forth in items (1) to (5) above which require high reliability and safety
4. Precautions against long-term use
Use of Azbil Corporation’s products, including switches, which contain electronic components, over a prolonged period may degrade
insulation or increase contact-resistance and may result in heat generation or any other similar problem causing such product or switch
to develop safety hazards such as smoking, ignition, and electrification. Although acceleration of the above situation varies depending
on the conditions or environment of use of the products, you are required not to use any Azbil Corporation’s products for a period
exceeding ten (10) years unless otherwise stated in specifications or instruction manuals.
5. Recommendation for renewal
Mechanical components, such as relays and switches, used for Azbil Corporation’s products will reach the end of their life due to wear by
repetitious open/close operations.
In addition, electronic components such as electrolytic capacitors will reach the end of their life due to aged deterioration based on
the conditions or environment in which such electronic components are used. Although acceleration of the above situation varies
depending on the conditions or environment of use, the number of open/close operations of relays, etc. as prescribed in specifications
or instruction manuals, or depending on the design margin of your machine or equipment, you are required to renew any Azbil
Corporation’s products every 5 to 10 years unless otherwise specified in specifications or instruction manuals. System products, field
instruments (sensors such as pressure/flow/level sensors, regulating valves, etc.) will reach the end of their life due to aged deterioration
of parts. For those parts that will reach the end of their life due to aged deterioration, recommended replacement cycles are prescribed.
You are required to replace parts based on such recommended replacement cycles.
6. Other precautions
Prior to your use of Azbil Corporation’s products, you are required to understand and comply with specifications (e.g., conditions and
environment of use), precautions, warnings/cautions/notices as set forth in the technical documents prepared for individual Azbil
Corporation’s products, such as catalogs, specifications, and instruction manuals to ensure the quality, reliability, and safety of those
products.
