About This Manual
This manual contains information and warnings that must be observed to keep the
model MGG/MGS Electromagnetic Flowmeter Detector operating safely. Correct
installation, correct operation and regular maintenance are essential to ensure safety
while using this device.
In addition to this model MGG/MGS detector user manual, please refer to model
MGG10C/14C converter user’s manual for start-up, calibration, trouble-shooting,
operation, and maintenance of the complete Electromagnetic Flowmeter.
For the correct and safe use of this device it is essential that both operating and
service personnel follow generally accepted safety procedures in addition to the safety
precautions specied in this manual.
The following symbols are used in this manual to alert you to possible hazards:
Denotes a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
WARNING
Failure to observe these precautions may produce dangerous conditions that could
result in operator injury or in physical damage to the device.
Safety Messages
Carefully read this section before in stalling or operating this device.
To prevent the gas or liquid in the pipe from escaping, do not remove the
electrode cover or the electrodes when the detector is installed on a pipe.
ELECTRIC SHOCK HAZARD! Turn the power supply o before wiring.

WARNING
This detector is heavy. Dropping it could cause personal injury or damage to the
device.

Safety Azbil Corporation
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.
MagneW FLEX+/PLUS+ Electromagnetic Flowmeter Detector iii
Safety Azbil Corporation
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.

Detector
There are three types of model MGG/MGS Electromagnetic Flowmeter Detectors:
Wafer detectors, Flange detector, and Union / Hose / Clamp detector. The type of
detector you choose depends on your specic installation requirements. All types of
detectors function such that when a conductive uid passes through the detectors, an
electromotive force signal proportional to the ow rate is generated.
WARNING
To prevent the gas or liquid in the pipe from escaping, do not remove the
electrode cover or the electrodes when the detector is installed on a pipe.
