The explosion-proof electromagnetic flowmeter adopts the world's latest technology. By using constant current low-frequency ternary rectangular waves or dual frequency rectangular waves for excitation, it not only has the advantages of rectangular wave magnetic fields, but also overcomes the disadvantages of sine wave magnetic fields; It can also eliminate errors caused by fluctuations in power supply voltage, changes in power supply frequency, and changes in excitation coil impedance; And it has excellent zero stability and is not affected by fluid noise interference. Therefore, it has the characteristics of high stability and high reliability. The measurement principle of explosion-proof electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. The explosion-proof electromagnetic flowmeter consists of a sensor and a converter. The sensor is installed on the measurement pipeline, and the converter can be combined with the sensor to form an integrated electromagnetic flowmeter. The converter is installed within 30 meters or 100 meters of the sensor, and is connected by a shielded cable to form a separated electromagnetic flowmeter. The main components of the explosion-proof electromagnetic flowmeter sensor are: measuring tube, electrode, excitation coil, iron core, and magnetic yoke housing. Explosion proof electromagnetic flowmeter is mainly used to measure the volumetric flow rate of conductive liquids and slurries in closed pipelines. Explosion proof electromagnetic flow meters are widely used in industries such as petroleum, chemical, metallurgical, textile, food, pharmaceutical, papermaking, as well as environmental protection, municipal management, water conservancy construction, etc., such as water, sewage, mud, pulp, various acids, alkalis, salt solutions, food slurries, etc.
