Product details

SISEN 220V electromagnetic flowmeters are widely used to measure volume flow of conductive liquids and liquid-solid two-phase fluids. The measurement principle of electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. In the right figure picture, the two electromagnetic coils on upper and lower ends generate a constant or alternating magnetic field. When theconductive medium flows through the electromagnetic flux and cut the magnetic induction line, an induced electromotiveforce will be generated and detected by two measuring electrodes. The magnitude of induced electromotive force is proportional to the velocity of conductive medium, magnetic induction intensity of magnetic field and conductor width(flowmeter measuring tube diameter), then it will come to the medium flow by calculation.



The equation of Faraday's Law of induced electromotive force:


Where:E=induced electromotive force; D=measuring tube diameter;B=Magnetic FieldStrength;V=Velocity of Process Fluid(m/s); K=Proportionality Constant(It is related to magnetic field distribution and axial length.)


Working power supply

·110/220V(AC): Applicable to AC power supply(common);

·24V(DC): Being required for some special conditions such as anti-Explosion requirement;


Output signals

·4-20mA output:suitable for long-distance analog signal transmission; ·Frequency/pulse output:used for meter calibration and accumulative flow output;

·RS485 communication:It can support networking of multiple electromagnetic flowmeters and long-distance data transmission; Users need to select output signals according to actual conditions and supporting equipment.


Selection of grounding ring

· Grounding ring is used to ground the measured medium to improve the stability of the electromagnetic flowmeter measurement. Because the grounding ring needs to be in contact with the measured medium, there is a possibility of corrosion and wear of grounding ring, which needs to be replaced periodically.

· Instead of using grounding ring, FLDC series electromagnetic flowmeter has adopted grounding electrode to guarantee long-term stability of grounding and high accuracy. If the stray current is too large to guarantee the normal measurement of the electromagnetic flowmeter, such as the leakage current of the electrolytic cell along the electrolyte,a grounding ring would be recommended to be used.

Some small-caliber electromagnetic flowmeters have only two electrodes, and users can choose double grounding rings according to site requirements.

· When installing the grounding ring, the grounding ring needs to be put on the right position to avoid affecting the flow field of the measured medium.
