1. APPLICATION
The POLARIS MA1 electromagnetic flow meter has been designed to measure volume flow rates
of electrically conductive liquids in closed piping systems. Measurements can be done in both flow
directions, with high measurement accuracy over a wide range of flow rates. The minimum required
conductivity of the measured medium is 5 µS/cm.
The microprocessor controlled MA1 transmitter processes measurement data and displays and
transmits various types of measurement results. The MA1 supports the option of
®
HART communication protocol for use with PACTware. Although basic configuration settings such
as transmitter calibration are defined at the factory, other settings such as those for measurement
data processing, analysis, display and output are user definable.
User settings are protected by a user definable password.
Settings that are essential for proper operation of the transmitter in conjunction with the sensor
(e.g. calibration and initialization values) are accessible only to service technicians via a password
that is not provided to customers.
2. MEASUREMENT PRINCIPLE
The function of an electromagnetic flow meter is based on Faraday’s electromagnetic law. The
meter sensor consists of a non-magnetic and non-conductive tube with two embedded measuring
electrodes to pick up the induced voltage. To create an alternating magnetic field, two coils are
fitted onto the tube in parallel with the plane defined by the active parts of the measuring
electrodes. Now if a conductive liquid flows across magnetic field B, voltage U will appear on the
measuring electrodes proportional to the flow velocity v and the conductor length l.

Figure 1 – Measurement principle
As the magnetic flux density and distance between the electrodes are constant, the induced
voltage is proportional to the liquid flow velocity in the tube. The value of the volume flow rate can
then be readily determined as a product of the flow velocity and square section of the tube,
Q = v x A.

3. TECHNICAL DESCRIPTION
The electromagnetic flow meter consists of a sensor through which the measured liquid flows and
an electronic unit where the low-level signal from the sensor is modified to a standardised form
suitable for further processing in various industrial electronic devices. The output signal is
proportional to the volume flow rate of the measured liquid. The only factor limiting the application
of electromagnetic flow meters is the requirement that the measured liquid shall be conductive and
non-magnetic. The electromagnetic flow meter can be designed either as an integral device or with
the sensor separated from the associated electronic unit. In the former case, the electronic unit is
fitted directly onto the meter sensor, in the latter case it is connected to the sensor by a special
cable.
The sensor design shall take into consideration the type of the measured liquid and its operational
parameters. To facilitate fitting into the liquid piping, the sensor can be provided with end flanges or
as a wafer style design. The supply voltage, types of output signal and communication interface
can be selected according to the customer requirements.
4. SENSOR TECHNICAL PARAMETERS
The sensor environment must be free of any strong magnetic fields.
4.1. Selection of correct sensor size
The following table shows minimum and maximum flow rates for various sensor sizes and flow
velocities ranging from 0.33-33 ft/s (0.1-10 m/s). The best operational properties will be achieved at
the flow velocity range of 1.64-16.4 ft/s (0.5 to 5 m/s). The measurement accuracy is degraded at
lower velocities while at higher velocities the turbulences and contact edges may cause
undesirable interference.
Minimum and maximum flow rates for various sensor sizes
Qmin corresponds to flow velocity 0.33 ft/s (0.1 m/s)
Qmax corresponds to flow velocity 33 ft/s (10.0 m/s)

4.2. Selection of electrode material
In most cases, electrodes made of stainless steel, quality grade 1.4571 (17248) are satisfactory.
These electrodes come standard for the rubber liners. For more corrosive applications it may be
desired to go to Hastelloy C4 electrodes, which are standard with the PTFE and ECTFE liners. On
request, tantalum or titanium electrodes can be provided.
4.3. Selection of sensor tube lining
The sensor lining material selection depends on the operational parameters of the measured liquid.
Technical rubber
This lining material is suitable for less corrosive liquids and operational temperatures from +32°F
(0°C) to +176°F (+80°C). It is sufficient for most applications in water supply and waste water
treatment plants. Technical rubber is available as hard rubber or soft rubber. Soft rubber lining is
recommended for liquids containing abrasive particles, such as sand grains.
PTFE
A universal solution for highly corrosive liquids and temperatures ranging from -4°F (-20°C) to
+302°F (+150°C). Typical applications are in the chemical and food processing industries.
ECTFE
A similar solution as PTFE except used for larger line sizes. Temperature range from -4°F (-20°C)
to +266°F (+130°C).

4.4. Integral or remote meter version
The Electronic unit can be installed directly on the sensor (integral version) observing the operating
conditions of the sensor or be mounted separately on the outside (remote version).
4.4.1 Remote version
The remote meter version is to be used at the measurement spots with ambient temperature
exceeding 140°F (60°C) where the reliable function of the electronic unit would not be ensured at
all times. In such cases, use the remote meter version and place the separate electronic unit at a
location where the ambient temperature never exceeds this rating. For process temperatures
higher than 212°F (100°C) it is recommended to use the remote version.
Furthermore, the transmitter needs to be mounted separately from the sensor if
the mounting area is difficult to access
there is a lack of space
there is strong vibration
Figure 2 - Proper installation of cables at high humidity and wetness
The Electronic unit has to be mounted free of vibrations!
Caution:
The electrode cable must be fixed. If the conductivity of the medium is low,
cable movements may change the capacity considerably and thus disturb the
measuring signal.
Do not lay the cables close to electrical machines and switching elements.
Equipotential bonding must be ensured between sensor and transmitter.
Do not connect or disconnect the field coil cable before the primary power of the
meter has been disconnected.
To prevent electromagnetic interference via the connecting cable, the sensor and separate
electronic unit of the meter in the remote version should be located as close as possible to one
another.
The maximum cable length depends on the conductivity of the measured liquid (see Fig. 3).

5. COMISSIONING
5.1 Installation of electromagnetic flow meters
The meter installation work shall be performed in strict observance of the procedures and rules
described in this manual.
To prevent undesirable interference, the power cables shall be laid at least 10 inches (25 cm) away
from all signal cables. The signal cables include the cable connecting the sensor and the
associated electronic unit (in the case of a remote meter version) and output signal cables. All
cables shall be laid outside the thermal insulation layer on the piping (if any). Only shielded
conductors shall be used to connect the output signals.
In applications where high levels of electromagnetic field interference at the measuring location can
be expected (e.g. in the vicinity of power frequency converters), the remote meter version should
be avoided. In these cases it is also recommended to include a filter in the power supply line to the
electronic unit.
Filter specification: The filter is intended to suppress dissemination of the undesirable high
frequency disturbances from the power supply cable to the flow meter system. Use any commercial
filter of suitable parameters including protection class, and install it as close to the meter as
possible. If need be, the filter can be placed in a special protection housing. When installing the
filter, observe the applicable safety regulations.
Rated voltage:
Rated current:
Suppression characteristic:
250V/50Hz
0.5A and more
10kHz: 10 to 20dB
10MHz: 40dB
5.2 Piping
No chemical injection or batching unit (such as chlorine compound injector) should be located at
the input side of the sensor. The insufficient homogeneity of the flowing liquid may affect the flowrate values indicated by the meter.
The meter performance will be the best if the liquid flow in the piping is well stabilized; therefore it is
necessary to observe specific rules for the sensor placement in piping. In the contact planes
between the sensor and the adjoining piping sections there should be no edges as these would
cause flow turbulence. Make sure that 5 diameters of straight piping section is provided before and
3 diameters after the sensor; their required length is proportional to the inner diameter of the piping
concerned.
If more than one flow-disturbing element such as pipe bend or fitting is located near the sensor, the
required length of straight piping section on the sensor side concerned should be multiplied by the
quantity of such elements.
In the cases of bi-directional flow-rate measurement, the same conditions concerning flow stability
shall be met at the input and output sides of the sensor.
In the cases where the pipe size larger than that of the meter sensor, it is necessary to use conical
reduction pieces with the angle of taper not exceeding 15°. In the cases of bi-directional flow
measurement, the minimum length of straight piping sections on both sides is 5 DN. In horizontal
sensor installations, to prevent bubbling, use concentrically-fitted reduction pieces (see standard
ČSN EN ISO 6817).
Pipe narrowing sections with angles not exceeding 8° can be taken for straight sections.
In the cases where the liquid is pumped, the flow sensor shall always be placed at the output side
of the pump. The required length of the straight piping section between the pump and sensor is at
least 25 diameters.
The sensor shall be always placed before the closing valve in the piping.
14
62-600 POLARIS Electromagnetic Flow Meter
62-600 POLARIS Electromagnetic Flow Meter
13
The sensor can be fitted in the piping in either horizontally or vertically. However, make sure that
the electrode axis is always horizontal and, if the sensor is mounted in a horizontal position, the
flange section for attachment of the MA1 faces upwards.
In the cases where the sensor is mounted in a vertical position, the flow direction shall always be
upwards.
To ensure correct meter function at all times, the measured liquid shall completely fill up the sensor
and no air bubbles shall be permitted to accumulate or develop in the sensor tube. Therefore the
sensor shall never be placed in the upper pocket of the piping or in a vertical piping section where
the flow direction is downwards.
In piping systems where complete flooding of the piping cannot always be guaranteed, consider
placing the sensor in a bottom pocket where full flooding is ensured.
If the sensor is located near a free discharge point, such point shall be by at least 2 diameters
higher than the top part of the sensor.
Make sure that the adjoining piping is clamped/supported as close to the sensor as possible, to
prevent vibrations and damage to the sensor.
In applications where continuous liquid flow is essential, a bypass shall be provided to allow for
sensor servicing. A sensor bypass may also be a reasonable solution in the cases where, to
dismantle the flow sensor from the piping, liquid from a very long piping section would have to be
discharged.

5.3 Earthing
Every sensor, with the exception of ½” (DN20), has a third grounding electrode provided at the
base of the spool piece. Additional grounding is possible utilizing the blue grounding lugs on the
neck of the sensor. A connection should be made to the electrically conductive piping (mating
flanges) upstream and downstream of the sensor to the grounding lugs. Grounding rings can also
be provided if the sensor is installed in non-conductive piping.
When using a remote transmitter, additional grounding is possible by connecting the grounding lug
on the sensor to the external grounding on the remote transmitter housing using a copper
2
conductor of cross-section 4mm .
Figure 18 – Grounding the
remote transmitter
5.3.1 Cathodic protective units
With a remote transmitter, ensure the transmitter is isolated from earth ground. Transmitter should
be at same potential as sensor. Ground everything to the same ground as the cathodic protection.
Warning
According to EN 50178:1997 all electrical circuits with protective safety isolation
without any protection against contacts must observe the following maximum
voltages:
Maximum AC voltage (root mean square value) 25 V
Maximum DC voltage 60 V
Do not connect PE to any higher voltage!
5.4 Remote transmitter with IP68 sensor.
The transmitter is supplied with a permanently attached connecting cable in protection class IP67.
The other end of the connecting cable is loose. The customer connects the cable to the sensor
terminal box itself.
Terminal box is equipped with a gland M20x1.5 and terminal board with WAGO terminals. The
housing is capped with O - ring. In this case it is the sensor with IP67 protection.
62-600 16
POLARIS Electromagnetic Flow Meter
17
62-600 POLARIS Electromagnetic Flow Meter
For a sensor with IP68 protection, the inside of the terminal box must be filled with supplied resin
GHB1.
Potting compound GHB1 (250 ml) including the necessary accessories are included in delivery for
remote version IP68.
The application resin procedure GHB1:
Remove the protective foil.
Mix the two components about 2 min.
Place the funnel.
Cut off the bag with the resin.
Pour the contents of the bag to the brim to the terminal box.
Curing time mixture is up to 150 minutes. Temperature during potting is +15°C to +30°C.
6. MA1 TRANSMITTER: MODE OF OPERATION AND
CONFIGURATION
6.1 System design
The meter consists of a sensor and a MA1 transmitter. The device can be used to perform
measurements with any liquid, conductive media, providing that the sensor’s material is suitable for
the product being used.
The MA1 transmitter generates the inductive current necessary for the magnetic field and
preprocesses the induced voltage at the electrodes.
6.1.1 Data memory chip DSM
The replaceable data memory chip (DSM) is an EEPROM device in a DIL-8 housing, located in a
socket on the power supply board. It contains all characteristic data of the sensor e.g. sensor
constant, version or serial number. Consequently, the memory module is linked to the sensor and
in case of a transmitter replacement it has to remain by the sensor!
After replacing the transmitter or its electronics, the DSM will be installed in the new transmitter.
After the measuring system has been started, the measuring point will continue working with the
characteristic values stored in the DSM. Thus, the DSM offers maximum safety and high comfort
when exchanging device components.

6.1.2 Safety of operation
A comprehensive self-monitoring system ensures maximum safety of operation.
Potential errors can be reported immediately via the configurable status output. The
corresponding error messages will also be displayed on the transmitter display. A failure of the
auxiliary power can also be detected via the status output.
When the auxiliary power fails, all data of the measuring system will remain in the DSM
(without back-up battery).
All outputs are electrically isolated from the auxiliary power, the sensor circuit and from each
other.

The low-flow cut-off can be set to values between 0 and 20% using the software. The set value
refers to the upper range value. If the measured value is lower than the set volume, the flow rate
will set to 0.0. This results in the analog output being set to 0/4 mA, and the pulse output will stop
generating pulses.
The configurable hysteresis takes effect in only one side while exceeding this limit.

If the transmitter is mounted separately from the sensor, the following cables must be used:
Electrode cable and field coil cable as shielded twisted pair. In order to protect the cable from
external interference, the twisted-pair wires are covered by an additional, overall shield e.g.
PAARTRONIC CY-CY-LiYCY (TP) 2x2x0.25mm² (UNITRONIC CYPiDY (TP) 2x2x0.25mm²).
At cable length more than 10m a wire cross section of at least 0,5mm² is required e.g.
PAARTRONIC CY-CY-LiYCY (TP) 2x2x0.5mm².
The outer shield is grounded by means of special EMC-compliant cable glands at both ends of the
cable.

11. MAINTENANCE AND REPAIR
The MA1 meter is designed as maintenance-free performance. It contains no parts which have to
be replaced or adjusted cyclically.
While commissioning or maintenance, mains power must be switched off. Do not connect or
disconnect the wirings between sensor and transmitter while power is on.
The transmitter electronics may be exchanged only as a complete module. A completely new
transmitter may also be purchased.
11.1 Replacing the transmitter
The transmitter can be replaced in the field without effecting the calibration of the flow meter when
the DSM chip is also replaced.
1) Remove current transmitter by unscrewing the four screws on the sensor neck and
exposing the sensor wiring.
2) Unplug the sensor from the current transmitter.
3) Remove the DSM chip (refer to section 6.1) from the power board. To get to the power
board, remove the faceplate and display module.
4) Plug the current DSM chip into the new transmitter on the power board. The same
procedure can be used as was completed on the removal of the DSM chip.
5) Connect the transmitter wiring to the current sensor, similar to step 2.
6) Screw on the new transmitter to the current sensor.
7) Transmitter is now operational with the same settings as original calibration.

12. MA1 Menu Structure
12.1 Introduction
The MA1 unit can be operated depending on equipment by using the keyboard or via PACTware
using HART protocol.
In the following, transmitter operation and parameterization using the keyboard are described. The
keyboard is located in the electronic compartment and covered by an inspection window.
Figure 21 - MA1 Transmitter with keyboard
12.2 Display
The display has an integrated back lit, alphanumeric display with two 16-character lines.
Measurement data and settings can be read directly from this display.
The LCD display is designed to be operated at temperatures ranging from -4°F to +140°F (-20 °C
to +60°C) without incurring any damage. However, at freezing or near-freezing temperatures, the
display becomes slow and readability of the measured values is reduced. At temperatures below
+14 °F (-10°C), only static values (parameter settings) can be displayed. At temperatures
exceeding 140°F (60°C), contrast decreases substantially on the LCD and the liquid crystals can
dry out.
12.3 Operating modes
The MA1 can be operated in the following modes:
1.
Display mode:
In display mode, measured values can be displayed in
various combinations and settings can also be displayed.
Parameter settings cannot be changed in this mode. Display
mode is the standard (default) operating mode when the
device is switched on.
2.
Programming mode:
In programming mode, parameters can be redefined. After
entering the correct password, changes that are permissible
for the customer (customer password) or all functions
(service password for technicians) can be realized.
NOTE – If password is manually changed it must be saved!
If the customer password is lost the manufacturer cannot
retrieve it without returning the unit.

13.11.1 Sensor constant C
The sensor constant C is the calibration value of the sensor connected to the transmitter. The
calibration value must be entered in the MA1 to ensure a correct measurement. The constant will
be defined after the calibration of the meters and can be found on the rating plate of the sensor.
After selecting the Sensor constant function, press to display the current setting.
Sensor constant /mV
01234.56 l/h
As mentioned in Section “12.4.3.2 Input window / modify a value”, the current value can be
changed.
CAUTION:
Changing sensor constant C to a value that differs from the value on the rating
plate of the sensor connected to the flow meter will result in false readings!
Note:
The sensor constant must always be preceded by a plus or minus sign. The delivery
default setting is a plus sign. If inlet and outlet section are interchanged when the
device is installed (the flow direction is indicated by an arrow on the sensor), the
transmitter will display a “forward flow” negative measurement value. If the (plus or
minus) sign of the sensor constant is then changed without changing the actual
value, a plus sign will again be displayed. No changes need be made in the
disposition of the electrical connections (wires).
13.11.2 Sensor type
The function Sensor type contains the type of the sensor with which the transmitter has been
delivered. The distinction is necessary and required because the flow rate measurement uses
different calculations depending on the type of sensor. After selecting this function, press
to
display the current setting.
Sensor type
[ PITY ]
This type code can be found on the sensor rating plate. This setting is defined by the vendor when
the device is first put into operation at the factory. It should only be changed if the transmitter is
mounted onto another sensor.
13.11.3 Inside diameter
The inside diameter of the sensor connected to the transmitter is necessary for calculating the
mean flow velocity. The inside diameter must be checked in the MA1 (on mm exact) to ensure a
correct measurement. After choosing the function “inside diameter” and pressing , the following
selection field will be displayed:
Inside diameter
50 mm
As mentioned in Section “12.4.3.2 Input window / modify a value”, the current value can be
changed.

As mentioned in Section 12.4.3.1 Selection window / make a selection, the operator can toggle
between these languages:
 German,
 English.
13.11.5 Excitation frequency
With the help of the function Excitation frequency, you can set the excitation frequency of the field
coil current. Since the excitation frequency depends on the sensor, it cannot be assigned freely.
The excitation frequency defaults to 6.25 Hz.
Excitation frequency
[ 6.25 Hz ]
The selection is confirmed and taken over with the -key.
Caution!
If the excitation frequency is changed, then a reference calibration must be
accomplished. Otherwise the measuring accuracy is not ensured.
13.11.6 Mains frequency
In order to ensure the mains frequency (50 Hz or 60 Hz) optimal interference suppression, the input
of the frequency is necessary. The standard setting is 60 Hz.
After choosing the function Mains frequency and pressing , the following selection field will be
displayed:
Mains frequency
[60 Hz]
The selection is confirmed and taken over with the -key.
13.11.7 Flow direction
This function allows the operator to define the flow direction that the transmitter will evaluate. Only
“forward” should be selected to prevent reverse flow from being measured. The standard factory
setting is “forward & reverse.” After selecting the Flow direction function, press to display the
current setting.
Flow direction

13.11.8 Software version (information field)
After selecting this function, the version of the transmitter software will be shown (example: 1.06):
Version of MA1
001.06
13.11.9 Serial number (information field)
With the help of the Serial number function, the transmitter is assigned to an order. This number
provides access to internal vendor data if the device needs servicing. The serial number is printed
on the rating plate of the transmitter. After selecting this function, press to display the following
information field:
Serial number:
100683
This entry should never be changed so as to ensure that the sensor, the transmitter and the
documents created within quality management are assigned correctly.
13.11.10 Show system errors
With the help of this function, you can show the error code of the system errors that have occurred.
The integrated diagnostic system of the MA1 distinguishes between two types of errors. Self-test
errors such as problems with a sensor line or inconsistent parameter inputs are displayed as
textual error messages. Once the error has been eliminated, the message automatically disappears
from the display.
Errors that are attributed to system memory or software, division by zero, or a fault in the
electronics unit are designated as system errors. These error messages are not reset
automatically after the error (usually of very brief duration) is eliminated.
Section 14 has more information on error messages.
