2 PRODUCT DESCRIPTION
2 . 1 OPERATING PRINCIPLE
The electromagnetic sensor is used to measure the flow rate of liquids (drinking water, wastewater, beverages,
fertilizers, chemical products, and any other liquid) that have an electrical conductivity of at least 5S/cm.
Electromagnetic flowmeters are the best solution for measuring the flow rate liquids because of fast response
times, great measurement accuracy, and a passage tube that does not present any obstruction to the liquid
flow, therefore no pressure drop in the pipe. Furthermore, since they do not use any moving parts, they require
virtually no maintenance.
EUROMAG electromagnetic flowmeters cover a wide variety of applications (e.g., water flowmeters, wastewater
flow measurement, fertilizer flow measurement, etc.) and respond to every customer request thanks to the wide
range of models. Meters are available in wafer, flanged, threaded, and insertion versions from DN6 to DN2000
in pressure class up to ANSI900.
In order to perform its measuring function, the sensor must be combined with a converter.
The converters are designed to meet all the needs of modern water management systems through flexible and
hybrid electronics, which, depending on the model, oers various electrical power solutions.
At the ends of a conductive fluid that moves with speed v in a
magnetic induction field Ban electromotive force e is induced
and can be expressed as:
e = kBDv
Where:
BB is constant by construction;
Dis constant and represents the distance
between the electrodes E1 and E2 (equivalent
to the flowmeter diameter);
vis the speed of the liquid;
kis the calibration constant;
The electromotive force «e» is proportional to the speed «v»
2 . 1 . 1 Bidirectional reading
The sensor has a possibility of bidirectional reading (i.e., it is able to read the flow of the liquid in both directions).
By convention, the sensor will output positive values if the liquid flows:

in the same direction as the arrow (enters in – and exits in +), the flow is positive, and the display will show
a reading without a sign

in the opposite direction to that indicated by the arrow (enters in + and exits in -), the flow is negative, and
the display will show a reading with a negative sign
Direct flow -> number without sign
Reverse flow -> negative number
1- Electromotive force (proportional to the speed);
2- Electrodes;
3- Magnetic field;
4- Coils;

3 . 3 INSTALLATION CONDITIONS
3 . 3 . 1 Positioning in relation to the plant
To ensure optimal working conditions, the flowmeter must be installed correctly inside the system. Correct and
incorrect installation positions are described and illustrated below.
The flowmeter must remain below the hypothetical blue line (piezometric level line), which connects the two
levels of fluid to be measured (Fig. 11).
NOTE: Avoid placing the flowmeter above the piezometric level line (Fig. 12).
3 . 3 . 2 Important guidelines for correct installation
The junction box on the sensor is designed to have the IP68 protection degree only when properly closed and
tightened. The manufacturer does not assume any responsibility for an improper closing by third parties.
For correct working conditions, please follow the important guidelines shown in the following figures. Improper
installation may result in an inaccurate measurement.
For partially filled pipes or with downward flow and free exit, the flowmeter should be placed in a U-shaped
tube (see Fig. 13).

IMPORTANT NOTE: THE SENSOR MUST ALWAYS BE COMPLETELY FULL OF LIQUID!
To ensure that the sensor is always completely filled with liquid, it is important to install it in the correct position
( ) and avoid all possible incorrect positions ( ).
We recommend installing the sensor on a vertical/sloped pipe with an upward flow direction (Fig. 19) to minimize
the wear and deposits in the sensor. Avoid the installation on vertical pipes with free exit (Fig. 20).
This installation secures the sensor full of liquid. This installation DOES NOT guarantee a
pipe full of liquid.
