1. Introduction
1.1. Operating Principle
The measurement is based on the principle of Faraday‘s law of electromagnetic
induction where a 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. Sensor Installation
Proper installation is extremely important in order for your flowmeter to work correctly. There are minimum
sensor installation requirements that need to be respected at all Times. Please note that Arkon cannot
warranty any installation which does not comply with these requirements.
Horizontal standard mounting
The sensor tube must always remain full. The best
way to achieve this is to locate the sensor in a low
section pipe, see the following picture.
It is mandatory to install the sensor in a section of
straight pipe with at least 5 times the pipe diameter
before sensor and 3 times after sensor.
Pipe reducers
If the pipe diameter is not the same as the
diameter of sensor, then pipe reducers can be
used. So as not to lose accuracy of the
measurement, the slope of reducers should not
exceed 8º.
Vertical mounting
When the sensor is mounted on a vertical section
of pipe, the flow direction must be upwards. In the
case of a downward flow direction, air bubbles can
collect in the sensor and the measurement could
be unstable and inaccurate.
Pumps
Never install the sensor on the suction side of a
pump or on a section of pipe where a vacuum is
possible.
Valves
Suitable location of a shutoff valve is downstream of
a sensor.

V1.5 12-1-2022
The sensor head has to be properly
tightened
During the sensor installation please check the
head and the four screws for proper tight.
Removal during maintenance
If the application requires removal of the sensor
for periodic maintenance, it is recommended to
install a bypass section as the drawing below.
All MAGE1 sensors are supplied with a built in earthing electrodes that are 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.
2.2. 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 be
keeping the meter wet, this problem solve itself within 2-3 days and no other action is required at all.

3.2. Errors and Warnings
That is a list of the possible errors for MAGE1:
Empty Pipe
If the Empty pipe appears on the screen there is no medium in the pipes.
Excitation
Coils interrupted or disconnected.
AD-converter
AD converter fault.
Note: The error disappears when the cause of it is fixed. You can see the measurement when you touch any
of the controls.
Overloaded
That error occurs when the measured flow is bigger than 1.2 * Flow Qn. Depending on the size:
Generally that error will occur when the AD converter is overloaded. It can be because on the electrodes are
very big voltage or because the flow is really that high.

9.4. General Modbus RTU
The module complies with the Modbus serial line protocol [Reference 1].
Among other things, this implies a master-slave protocol at level 2 of the OSI model. One node, (the master),
issues explicit commands to one of the „slave“-nodes and processes responses. Slave nodes will not transmit
data without a request from the master node, and do not communicate with other slaves. Modbus is a mono
master system, which means that only one master can be connected at any single point in time. Two modes
of communication are possible, Unicast and Broadcast. Unicast mode is where the master sends a request
to one slave device, and waits a specified time for a response. In Broadcast mode the master sends out a
request to address „0“, which means that the information is for all slave devices on the network. In Broadcast
mode there is no response from the slave devices.
The Modbus frame is shown below, and is valid for both requests and responses.
Further details of the Modbus protocol can be found in Reference 1 and 2.

9.7. Modbus function codes
This device supports following function codes: 3, 16 and 17.
Function code 3 and 16 are used for accessing registers. Function code 17 (report slave ID) will return a
structure of identification information of the device. Below the different function code exceptions are described.
Function code 3 (Read holding registers)
General exceptions:
• Requesting less than 1 or more than 125
registers => Exception 3 (Illegal data value)
• Requesting more than max. message size =>
Exception 2 (Illegal data address)
• Requesting data above/crossing limitation of
max. register address (0xFFFF) => Exception 2
(Illegal data address)
• If the end address is only part of a mapped
holding register item (e.g. one half of a longint
value) => Exception 2 (Illegal data address)
Application exceptions:
• Application errors => Exception 2 (Illegal data
address)
Holes/register alignment:
• The read command always returns data if no
exception is given. Bad start/end alignment will
result in only parts of the data item being read.
• Holes in the holding register map return
Exception 2 (Illegal data address)
Function code 16 (Write multiple registers)
General exceptions:
• Exceeding max. message size => Exception 2
(Illegal data address)
• Writing data above/crossing limitation of max.
register address (0xFFFF) => Exception 2(Illegal
data address)
Application exceptions:
• Application errors => Exception 2 (Illegal data
address)
• Application errors include writing to ReadOnly

Holding registers memory map
When writing to the Holding registers, data validity is not checked. Writing incorrect values can result in
unexpected behaviour of the device. In any further explanations, the following data types are used:
•Longint –Number consisting of 32 bits, formed by 2
Modbus registers. It is necessary to write both Low and
High Word of this item, the register number always has
to be an even number. Not meeting these requirements
will cause an Exception 2 error (Illegal data address). In
case information about the number of decimals is
available, then the final number is given by the following
formula: Y = X * 10^(-DEC), where Y is the final number,
X the read number, and DEC the number of decimals.
•Bool –this item can be read, but its value has no
meaning. Writing value 1 to this item will cause an
unspecified operation to be performed (resetting the flow
totalizers, etc.) It is necessary to write both Low and High
Word of this item, the register number always has to be
an even number. Not meeting these requirements will
cause an Exception 2 error (Illegal data address).
