A meniscus flow control device comprising: a plurality of temperature measurers measuring a temperature in a width direction of a mold receiving molten steel therein at a plurality of positions; a meniscus flow detection unit detecting a relative temperature value for each position, which is measured by the plurality of temperature measurers in a meniscus flow form of the molten steel; a flow pattern classification unit analyzing the meniscus flow form detected by the flow detection unit to classify the meniscus flow form into one flow pattern type of a plurality of previously stored flow pattern types and determine whether the flow pattern type is normal or abnormal; a magnetic field generation unit installed outside the mold to generate magnetic fields and thereby to control the flow of the molten steel; and a flow control unit maintaining an operation of the magnetic field generation unit in the present state when the flow pattern type, which is classified by the flow pattern classification unit, is determined as a normal state, and controlling the operation of the magnetic field generation unit to adjust the meniscus flow to be normal when the classified flow pattern type is determined as an abnormal state; wherein, the flow pattern classification unit classifies a flow pattern type into one flow pattern type of the plurality of flow pattern types that are previously stored, and determines whether the classified flow pattern type is normal or abnormal, on the basis of: whether a temperature difference (ΔT H-L) between a minimum temperature and a maximum temperature of a plurality of measured temperature values measured by the plurality of temperature measurers satisfies a range equal to or greater than a first reference value and equal to or less than a second reference value; whether each of temperatures T E1 and T E2 at both edges of the meniscus, which are measured by the temperature measurers disposed at both outermost sides, is equal to or greater or less than a center temperature Tc measured by the temperature measurer installed at a central portion of the meniscus; and whether a deviation ΔT E1-C and ΔT E2-C between each of the temperatures T E1 and T E2 at both edges and the center temperature T c is equal to or greater or less than a third reference value. a plurality of temperature measurers measuring a temperature in a width direction of a mold receiving molten steel therein at a plurality of positions;
