LUCH Series of Intelligent Magnetoelectric Flowmeter
Overview
LUCH series intelligent magnetoelectric flowmeter is a kind of speed type flowmeter, which has merits of both vortex flowmeter and electromagnetic flowmeter such as no moving parts and measuring steadily. It can measure volumetric flow of conductive liquid such as pulp, slurry, sewage, waste water and solid-liquid two-phase suspension liquid, including strong corrosive liquid such as acid, alkali, salt, and so on. The product is used widely in industries such as petroleum, chemical industry, metallurgy, textile, food, pharmacy, papermaking, etc. And it is also used widely in fields such as environmental protection, municipal administration, water conservancy construction, and so on.
Operating Principle
LUCH series intelligent magnetoelectric flowmeter uses Faraday’s law of electromagnetic induction. When liquid is moving, the vortex in pipeline make it cut magnetic field and produce induced electromotive force, which is detected by measuring electrode, then amplified, filtered, shaped by pre-circuit, and then it is sent to the microprocessor with core of CPU to complete data’s collection, amplifying and processing, realize displaying of instantaneous flow and accumulative flow, also realize communication and control between flow date and microcomputer system.
