여자 코일(210) 및 검출 코일(220)은 침지 노즐(163)을 사이에 두고 배치된다. 여자 코일(210)로부터, 침지 노즐(163)의 중공부를 흐르는 용강과 교차하도록 자계를 발생시키고, 당해 자계의 시간 변화를 유도 기전력으로서 검출 코일(220)에 의해 검출한다. 연산부(400)는, 당해 유도 기전력에 기초하여, 침지 노즐(163)의 중공부를 흐르는 용강의 유량을 도출한다. A flow rate measurement system being a flow rate measurement system that measures a flow rate of molten metal flowing through a hollow portion of a pipe includes an excitation coil that generates a magnetic field so as to intersect with the molten metal flowing through the hollow portion of the pipe; current supply processor circuitry that supplies an alternating exciting current to the excitation coil; a detector that detects a signal based on a magnetic field generated from the excitation coil by an alternating exciting current flowing through the excitation coil or a time variation in the magnetic field; and flow rate deriving processor circuitry that derives the flow rate of the molten metal based on the signal detected by the detector, wherein the pipe is arranged between the excitation coil and the detector, and a magnetic field that reaches the detector across the pipe is generated from the excitation coil.
