1. Introduction
1.1. Operating Principle
The measurement is based on the principle of Faraday‘s law on electromagnetic
induction in which an electric voltage is induced in an electrically conductive body
that moves in a magnetic field.
Liquid flows through a tube in the direction of the magnetic field. Liquid with a
certain minimum electrical conductivity induces a voltage which is detected by
two electrodes located in a 90 degree angle from the magnetic field and the flow
direction.
1.2. Applications
Water / waste
water
Chemical
industry
Food industry
Power
engineering
Agriculture
Effluent

1.3. Safety Instructions
Please read this manual carefully before using the product.
Keep this manual for future reference. Arkon Flow Systems, s.r.o will not be liable for any
damage caused by improper use of the product or its accessories.
If the device is used any different way than is specified, the electric protection may be disrupted.
The MAGX2 flow converter - flow-meter must not be mounted in explosive hazardous areas.
1.4. Unpacking the flowmeter
While unpacking the flowmeter, conduct a visual check of the
flowmeter upon receipt to make sure the product has not been damaged
during transport.
Check the completeness of the package. In case of any problem,
contact the Arkon sales department without delay.

2. Installation
2.1. Remote or Compact
Any MAGX2 flowmeter can be delivered in two versions; Compact with
IP67/IP68 or Remote. The compact version has the transmitter unit connected
directly to the sensor body. This version does not require any further mounting
or installation of the transmitter.
The remote version has a separated transmitter. It is connected to the sensor
with a cable. The cable entry into the sensor is protected by a junction box,
which can be potted to IP68 (page 11).
The cable entry on the transmitter side is through a M16x1.5 gland.
The cable type used for the connection between sensor and transmitter for remote versions: UNITRONIC®
LiYCY (TP) 0035 830, 2x2x0.5
The MAGX2 is equipped with an electronic board located inside the sensor neck. This board sends a digital
signal to the transmitter, unlike traditional flowmeters, which send an analogue signal. This allows the MAGX2
to carry its signal over much longer distances than conventional flowmeters; up to 500m is possible.
2.2. Sensor installation
Sensor dimensions can be found on page 54
Proper sensor installation is extremely important in order for your flowmeter to work correctly. Below, you will
find minimum sensor installation requirements that need to be respected at all time. Sensor must not be
installedneck facing down.

V2.14 1-2-2017
All MAGX2 sensors are supplied with 2 built in earthing electrodes which is sufficient for all applications with
metal pipes and tanks. However on applications where all pipes and tanks are manufactured from plastic, it is
recommended that earthing rings are also installed to ensure the maximum resistance of the sensor to earth
is <1 ohm.
To ensure correct meter operation make sure the earthing rings and sealings around are
centered.
2.3. Dry liner
Flowmeters with a Hard Rubber liner can show incorrect readings during the first 2-3 days after installation.
This is due to the fact that the time needed for transport and the time before installation is long enough for the
liner to dry out, and thus it changes shape/size. This change, in effect, affects reading accuracy. Simply by
keeping the meter wet, this problem solve itself within 2-3 days and no other action is required at all.

2.4. Installation of the transmitter
In case of a compact flowmeter version, the transmitter will need no further installation, and should be ready
for use. In case of a remote version, the following 4 steps are necessary.
Mount the transmitter to a wall, panel, or DIN-rail.
Wall mounting:
DIN-rail mounting:
Panel mounting:
Connect the transmitter to the signal cable from the sensor.
IP67 Transmitter
To do this, first open the transmitter housing by disconnecting the two parts of the transmitter housing with the
metal “key” that is provided with the meter
IP68 Transmitter
To do this undo four M6x22 screws using allen key nr.5 that is part of the delivery.
The electronics
have to be
protected against
direct sunlight and
high temperatures!
The transmitter
housing should be
exposed to minimal
mechanical strain
only (max. 1kg)!

After the meter is opened, pull the signal cable through the cable gland on the bottom of the transmitter
housing (see page 5).Connect the connector at the end of the signal cable from the sensor to the transmitter
circuit board.
Electrical installation should only be done by a qualified person. Standard safety regulations
for hazardous electrical installations have to be respected.
The O-ring sealing shall be exchanged every 6 months of operation.
Connect the transmitter to network power.
The customer is assumed to supply its own network power supply cable (90-250VAC, 24VDC or 12VDC,
depending on the type of power supply ordered with the flowmeter). Before connecting to network power, the
cable needs to be properly connected to the transmitter.
First pull the cable end through one of the cable glands (ideally the first on the left looking at the transmitter
housing from the back-side) on the bottom of the transmitter.
Recommend 3x1mm round crosscut cable.
After connecting the power cable, close the housing and connect the cable to network power. This will make
the flowmeter switch on.
For electrical connection the appropriate temperature rated cables have to be used
(Ta=70degC)
Set up the transmitter for use.
You are now ready to start using your flowmeter or to customize its settings as per your requirements. For
example;
- Set-up the measurement unit of flow-rate displayed, e.g. m3/hr.
- Set up of the unit for the volume displayed. For all volume counters this same unit will be used.
2.5. Module installation
- Always check if the module does not have a bent or
broken pin, before placing it in the correct module slot of
the MAGX2 motherboard.
- Always make sure you place the module in the
correct slot of the motherboard! The name that is written
on the module itself has to match the name written next
to the slot. Placing the module in an incorrect slot can
cause damage to the module and the motherboard,
and has to be avoided by careful module installation!
-Check whether you are placing the module in the
correct position. It does matter how you turn the module
to fit the slot! The white line around the actual slot on the
motherboard indicates the correct position of installation.
The bevelled corner should be your point of orientation
(note the picture below).

Correct installation Incorrect installations
Any connection or disconnection of any module has to be done with network power to the
meter switched off.
2.6. Cables connections
The following diagrams show the connections of the cables between sensor and transmitter.
Sensor communication module version 7.1
Use this cable connection only for “sensor to
transmitter communication module - version 7.1”.
The RS232 Module is
placed in a different slot.
The RS232 Module is
placed in the correct
slot, but with the
bevelled corner in the
wrong direction.
