The contactless inductive flow tomography (CIFT) aims at reconstructing the velocity field in electrically conducting melts from externally measured induced magnetic fields. One of its possible applications is the velocity reconstruction in the continuous casting process. In this paper, we apply this method to the flow field in a small model (containing approximately 1.4 liters of the eutectic alloy GaInSn) of a mould for thin slab casting. It is shown that the flow structure in general, and the jet position and intensity in particular, can be reliably determined from magnetic field data using only a modest number (in the order of 5) of sensors.
