I.Specification:
LRLD type intelligent electromagnetic flowmeter is developed by our company adopts the most advanced technology at home and abroad , the electromagnetic transducer in Chinese words display, fast calculation, high precision, reliable measurement performance. Can be used to measure the acid, alkali, salt and other corrosive liquid or liquid mixed with solid , such as pulp, mud and contains a lot of sundry sewage and viscosity of medium. Is widely used in the chemical industry, metallurgy, paper making, pharmacy, food, environmental protection, chemical fiber, and other industries.
II.Working Principle:
LRLD type electromagnetic flowmeter is designed according to the Faraday law of electromagnetic induction. Installing a pair of detection electrodes on the measuring tube axis and the magnetic field lines are perpendicular to the pipe, when conducting liquid along the sounding pipe in the alternating magnetic field, magnetic field lines into a vertical direction, the conductive liquid cutting lines of magnetic force induced electric potential, the induction electric potential is checked out by the two detection electrodes on the measuring tube.
Represented by the following formula:E=KBVD
In the equation: E-Induction Electric Potential,K-Associated with the magnetic field distribution and the axial coefficient,B-Magnetic induction intensity,V-Conductive liquid average flow velocity,D-Distance of the two electrodes
III.Product Features:
*No moving parts, unimpeded flow components,Virtually No Pressure Loss
