| SISEN 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: E=KBDv 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.) Integrated type 路 The connecting cable between the converter and the sensor of integrated type electromagnetic flowmeter is completely eliminated, the price and installation cost are low and the display is intuitive; 路 Integrated type flowmeter is suitable for most working conditions, especially suitable for flow measurement of low conductivity fluid media, but not for conditions of high temperature liquid, severe vibration, severe dripping and water immersion; . When installed in an place where is hard to reach, maintenance is inconvenient; Default level of protection of integrated type is IP65; Electrode MaterialAnti-corrosion performance and applicable condition Stainless steel 316LApplicable: 1.
