This article aims to demonstrate that molten metal flow at a high temperature can be measured effectively in contactless manner by using external direct current magnetic fields. The device applied the present work is termed Lorentz force flowmeter (LFF) and based on exposing magnet system measuring drag acting it. Two series of measurements are reported. In first series, we perform model experiment laboratory eutectic alloy GaInSn, which liquid room temperature. second devoted two plant tests measurement aluminum alloy. both tests, equal flow. To generalize our results, also derive scaling law relates localized rate fluid with arbitrary electrical conductivity. shows LFF, if properly designed, has wide range potential applications ferrous nonferrous metallurgy.
