Features of intelligent anticorrosive electromagnetic flowmeter products
2012-2-24 9:12:33

采用世界最新技术。 Intelligent anti-corrosion electromagnetic flowmeter uses the latest technology in the world. The use of constant-current low-frequency three-value rectangular wave or double-frequency rectangular wave excitation not only has the advantages of a rectangular wave magnetic field, but also overcomes the shortcomings of a sine wave magnetic field; it can also eliminate power supply voltage fluctuations, power supply frequency changes, and excitation coil impedance changes Error; and has excellent zero stability and is not affected by the interference of fluid noise. So it has the characteristics of high stability and high reliability. The measuring principle is based on the Faraday's law of electromagnetic induction. The intelligent anti-corrosive electromagnetic flowmeter consists of a sensor and a converter. The sensor is installed on the measurement pipeline. The converter can be combined with the sensor and called an integrated electromagnetic flowmeter. The converter is installed When the distance is within 30 meters or 100 meters from the sensor, the two are connected by a shielded cable, which is called a separate electromagnetic flowmeter. The main components of the sensor are: measuring tube, electrode, excitation coil, iron core and yoke housing. It is mainly used to measure the volume flow in conductive liquids and slurries in closed pipes. Such as water, sewage, mud, pulp, various acids, alkalis, salt solutions, food slurry, etc., are widely used in petroleum, chemical, metallurgical, textile, food, pharmaceutical, papermaking and other industries, as well as environmental protection, municipal management, water conservancy construction and other fields.
