Abstract
Lorentz force velocimetry is an innovative technique for non-contact measurement of the flow rate and accumulated mass of moving conductive fluids like high-temperature liquid metal alloys. In this work we present the results of industrial tests of the Lorentz force flowmeter (LFF) at a secondary aluminum production plant. The measurements were carried out in an open channel, within which the primary melt is transported from the rotary furnace to the holding furnace. The uncertainty of measurement is obtained by comparing the measured accumulated mass with the results of preliminary weighting of the alloy components. Tables 2, Figs 4, Refs 5.
