Electromagnetic Flow Meter

Model# U-MAG

Description

U-MAG Series electromagnetic flow meter can be used to accurately measure the flow rate of liquids which is electrical conducting caustics, and mixed with liquid and solids. They are widely use through out industries of petroleum, chemical engineering, Pharmacology, paper making, electric power, environmental protection and so on forth.

Measuring / Working Principal

Electromagnetic flowmeter follows the faraday law of electromagnetic induction. When the conductive liquids flow through the electromagnetic flow meter, the induce electromotive force will be produced in the conductor and the induce electromotive force directly proportional to the velocity of conductive liquid, magnetic flux density and width of the conductor (Inside diameter) of flow meter such induce electromotive force is detected by a pair of electrodes on the tube wall of the flowmeter, and the rate of flow can be aquired by mathematical operation.
