Applicable to explosion-proof requirements of the higher places, using the world''s latest technology, using constant current of three value low-frequency square wave or dual frequency rectangular wave excitation, has both advantages of rectangular wave magnetic field, but also overcomes the disadvantages of sine wave magnetic field; also the error caused by the elimination of power voltage fluctuation, power frequency variation and excitation coil impedance change; zero stability and good and is not affected by the fluid noise interference. Which has the advantages of high stability,high reliability.
The measurement principle of LZD series explosion-proof electromagnetic flowmeter isbased on Faraday''s law of electromagnetic induction, explosion-proof electromagnetic flowmeter sensor is mainly composed of: measuring tube, electrode, excitation coil,magnetic yoke iron core and shell.
LZD series of explosion-proof type electromagnetic flowmeter is mainly used for measuring the enclosed volume flow in pipes of conductive liquid and slurry. Such as water, sewage, slurry, pulp, all kinds of acid, alkali, salt, food slurry, explosion-proof electromagnetic flowmeter is widely used in petroleum, chemical industry, etc..
