1. Introduction
1.5 Preliminary notes
Main parts of the electromagnetic flowmeter are:
■Sensor – installed in the tube with the use of flanges and
other joints;
■Converter – can be installed on the sensor (in compact
version) or remotely (in remote version) connected with
two pipes.
Electromagnetic flow meters have many important
advantages compared to their mechanical counterparts,
such as exceptional long-term stability, maximum process
reliability, and zero maintenance. As a result, these sensors
can provide accurate and reliable long-term measurements.
See the following paragraphs for more detailed information
on correct installation.
NOTE
Electromagnetic flow meters are designed
specifically to operate under the following basic
conditions:
▶the liquid must be conductive;
▶pipe must be always full and free from air and
bubbles;
▶the input and output distances must be on
recommended settings;
▶The grounding instructions must be followed.
1.6 Product identification
Each Sensor manufactured by Euromisure has an
identification plate (Fig. 1) that displays the following
information:
■MODEL: Sensor model;
■S/N: Sensor identification number;
■DN: Nominal diameter [inches or mm];
■PN: Nominal pressure;
■TEMP.: Maximum liquid temperature for process completion;
■IP: International degree of protection
■ELECTRODES: Electrodes material composition
■LINING: Lining material
■KA: Calibration coefficient
■CE: Marking
Fig. 1: Identification plate
NOTE
The identification plate must never be removed,
damaged, or changed. It must also be kept clean
from any dirt deposits, as the data contained are
the only safe and unambiguous way to recognize
the type of converter and be able to complete
the repair request form attached to this manual.

2. Product description
2.1 Operating principle
The eltctromagnetic 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 μS/cm.
Electromagnetic flow meters 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. Euromisure
eltctromagnetic flow meters cover a wide variety of applications
(e.g., water flow meters, 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.
NOTE
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, offers various
electrical power solutions.
At the ends of a conductive fluid that moves with speed vin a
magnetic field Ban electromotive force e is induced and can be
expressed as:
e = kBDv
Where:
■Bis constant by construction;
■Dis constant and represents the distance between the
electrodes E1 and E2 (equivalent to the flow meter diameter);
■vis the speed of the liquid;
■kis the calibration constant.
The electromotive force «e» is proportional to the speed
«v».

2. Product description
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

so as not to cause damage to the sensor itself
and connection flanges. Below you will find a
description of correct and incorrect lifting and
moving.
The proper lifting method (for transport and installation) of the
sensor is shown in Fig. 2. The flow meter must be lifted and
transported by properly harnessing the device on the side
parts of the flow meter, making sure that the slings (ropes,
bands, etc.) are fixed to the appropriate eyebolts.
WARNING!
Do not raise the flow meter harnessing
the converter (Fig. 3)!!
WARNING!
Do not move the flow meter with the lifting
device if it is not in the original packaging (Fig. 4)
or without adequate support that ensures the
required stability.
