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.

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.

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).

Use this cable connection only for “sensor to
transmitter communication module –version 8.0”.
“Please note that in different versions of the transmitter, 2 types of connections can be
used. These are 1 x 4-pin connector instead of a 2 x 2-pin connector as shown in the picture.”
Important: In case of IP68 transmitter it is needed to use silicone gel to extra protect cable glands from inside
of the meter. Pour neutral silicone gel into the cable gland from inner side and pull the cable 3mm out of the
housing to make the cable gland extra protected for IP68.

IP67 version –Touch buttons
Touch-buttons are working on capacitance principle therefore any
conductive material close to button's area will cause button press. Even
water can do it so it is strongly recommended to use key-lock when any
presence of water is expected. 30 seconds after turning the flowmeter
on, touch-buttons autocalibration is started so function of the
touch-buttons may be unstable.
IP68 version –Optometric buttons
Optometric buttons are working on a IR light reflection principle
therefore any strong source of light will cause button press or buttons
inactivity. In dusty areas or where direct sunlight shine directly on a
keypad it is recommended to use key-lock, operate the buttons after
cleaning the glass and shade from sunlight.
The MAGX2 transmitter has a key-lock possibility. You can lock
touch-buttons by touching the Esc key first followed by the Enter key
within one second. This will lock the flowmeter and there will be a lock
symbol on display.
Touching the buttons will have no effect on flowmeters function.
To unlock buttons touch the buttons same way as for locking.
If flowmeter is in cleaning electrode there is a lightning symbol
on display.
Upon starting the flowmeter, you will automatically see the main screen
of the menu.
If transmitter is switched off from power supply longer than 3 months,
output settings may be lost.
