2.2. Measuring principle
The operating principle of electromagnetic flowmeter is based on Faraday's law of
electromagnetic induction. The two electromagnetic coils at the upper and lower
ends as shown in Figure 3 generate a constant or alternating magnetic field. When
the conductive medium flows through the electromagnetic flowmeter, the induced
electromotive force can be detected between the left and right electrodes on the
wall of the flowmeter tube. The magnitude of the induced electromotive force is
proportional to the electrically conductive medium flow rate, the magnetic induction
density of the magnetic field, and the width of the conductor (the inner diameter of
the flowmeter measuring tube), and the flow rate of the medium can be obtained by
calculation. The induced electromotive force equation is as follows:
E=K×B×V×D
Where: E－Induced electromotive force
K－Meter constant
B－Magnetic induction density
V－Average flow speed in cross-section of measuring tube
D－Inner diameter of measuring tube
Figure 3
When measuring the flow, the fluid flows through a magnetic field which is
perpendicular to the flow direction. The flow of conductive fluid induces a potential
proportional to the average flow velocity, thus requiring the conductivity of the
measured flowing liquid to be higher than the minimum conductivity (5us/cm).
The induced voltage signal is detected by two electrodes and transmitted to the

Chapter 2 Introduction

converter via a cable. After a series of analog and digital signal processing, the
accumulated flow and real-time flow are displayed on the display of the converter.
2.3. Mechanical Construction
The electromagnetic flowmeter is mainly consisted of the following parts, see
Figure 4.
Figure 4
The electromagnetic flowmeter mainly consists of a sensor and a converter. The
sensor includes a flange, a lining, an electrode, a measuring tube, an excitation coil,
and a sensor casing, etc; the converter includes an internal circuit board and a
converter casing.
(1) Converter: Provide stable excitation current for the sensor, meanwhile
amplify the induced electromotive force obtained by the sensor and convert
it to standard electrical signals or frequency signals; at the same time, it
displays real-time flow and parameters for displaying, controlling and
adjusting thereof.
(2) Flange: for connecting process piping.
(3) Lining: Refer to a complete layer of electrically insulating corrosion resistant
material located at the inner side of measuring tube and flange sealing
surface.
(4) Electrode: A pair of electrodes is installed on the wall of the measuring tube
which is perpendicular to the magnetic line to detect the flow signal. The
material of electrode can be selected according to the corrosion

performance of the measured medium. It is also equipped with 1-2
grounding electrodes for grounding and anti-interference of flow signal
measurement.
(5) Measuring tube: The measured medium flows through the measuring tube.
It is made by welding non-magnetic stainless steel and flange, and the inner
side is equipped with insulation lining.
(6) Excitation coil: A group of coils is arranged on the upper and lower side of
external side of the measuring tube respectively to generate a working
magnetic field.
(7) Casing: Protect and seal the meter.
2.4. Application introduction
Electromagnetic flowmeter applies only to measure the real-time flow rate of an
electrically conductive liquid or liquid-solid two-phase flow, and has a flow
accumulation function. Theoretically, an ordinary type electromagnetic flowmeter
can measure the medium conductivity of not less than 5 μS/cm, but it’s proved that
the measured conductivity by the ordinary electromagnetic flowmeter is higher than
one to two orders of magnitude, at least more than 50μ S/cm. Meanwhile,
the conductivity measured online must prevail, for that measured offline may
be relatively higher due to carbon dioxide and nitrogen dioxide contained in the air
may dissolve into the medium.

rain. The ambient temperature ranges from -20°C to +60°C.
3The electromagnetic flowmeter shall not be installed in places with large
temperature variation and avoid high temperature radiation from the
equipment. If it must be installed therein, heat insulation and ventilation
measures shall be taken.
4The electromagnetic flowmeter shall avoid installing in an environment
containing corrosive gases. If it must be installed therein, ventilation and
anti-corrosion measures shall be taken.
5The electromagnetic flowmeter shall be installed avoiding strong vibration
as possible, such as violent pipe vibration. In this case, brackets for fixing
pipes on both sides of electromagnetic flowmeter shall be provided.
6Part of the sensor of electromagnetic flowmeters with IP68 (3 m under
water) protection level can be placed into the water. While the
electromagnetic flowmeter with IP65 protection level cannot be immersed
into the water or installed outdoors.
(2) Avoid interference of magnetic field
Do not install electromagnetic flowmeters near motors, transformers, or other
power sources which are prone to cause electromagnetic interference, near the
frequency converter or obtain power from the power distribution cabinet of the
frequency converter to avoid interference.
(3) The distance of the straight pipe
In order to ensure the measurement accuracy of flowmeter, it is recommended
to ensure that the length of the straight pipe on the upstream of the sensor shall
be at least 10 times of pipe diameters (10D), and the length of straight pipe on
