I. Overview:
measurement of electromagnetic flowmeters in closed conduits for conducting the volume of liquid and slurry flow, such as clean water, sewage, various chemical salt solution, slurry, pulp and other liquid foods, multiple electrodes and various lining greatly facilitated your choice, wide 30:1 flow range, a variety of intelligent structures, are widely used electric power, steel, chemicals, pharmaceuticals, environmental protection, rare earth and other industries.
Second, the working principle of:
electromagnetic flowmeter is based on the basic theory of Faraday's law of electromagnetic induction, when the conductor cutting magnetic line movement, conductor, will produce EMF. According to the principle, measurable conductivity of the fluid flow tube volume. Conducting the direction of fluid flow and electromagnetic field in the direction perpendicular to the direction of the catheter by applying a vertical alternating magnetic field, and in the lining of the duct wall with insulation installed on both sides of a pair of electrodes, two electrode catheters connected not only with the vertical axis but also with perpendicular magnetic field, when the conductive liquid flows through the catheter, the cutting lines of force due to the two electrodes to generate EMF UE
Third, technical parameters:
1) measured diameter: 10mm-1200mm
2) The flow rate range :0.3-10m / s
3）介质导电率:>5us/cm
4) Accuracy:
