Explosion-proof electromagnetic flowmeter
HNLDB series explosion-proof electromagnetic flowmeter using the latest technology in the world. Using constant current low frequency three-value rectangular wave or double frequency rectangular wave excitation, the advantages of the existing rectangular wave magnetic field, and overcome the shortcomings of the sine wave magnetic field, can also eliminate the power supply voltage fluctuation, power frequency changes and excitation coil impedance changes caused by the error, and has excellent 0-point stability and is not affected by the noise of the fluid. It has the characteristics of high stability and high reliability. Explosion-proof electromagnetic flowmeter measurement principle is based on Faraday law of electromagnetic induction, explosion-proof electromagnetic flowmeter consists of sensors and converters, sensors installed in the measurement pipeline, the converter can be connected with the sensor combination of the integrated electromagnetic flowmeter, the converter is installed 30 meters away from the sensor or 100 meters within the occasion, The two are connected by shielded cable, which is called separation type electromagnetic flowmeter. Explosion-proof electromagnetic flowmeter sensor main components are: measuring tube, electrode, excitation coil, iron core and magnetic yoke shell. Explosion-proof electromagnetic flowmeter is mainly used to measure the volume flow in the conductive liquid and slurry in the closed pipe. such as water, sewage, mud, pulp, all kinds of acid, alkali, salt solution, food slurry, explosion-proof electromagnetic flowmeter is widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, paper and other industries as well as environmental protection, municipal management, Water conservancy construction and other fields.
