Abstract Scope The contactless inductive flow tomography (CIFT) allows reconstructing the mean 3-dimensional flow structure of liquid melts by measuring the flow induced perturbations of one or more applied magnetic fields. These measurements are utilized to infer the flow field by solving a linear inverse problem using an appropriate regularization. We will give an overview of the application of CIFT to two models of continuous casting available at the Helmholtz-Zentrum Dresden-Rossendorf and report recent developments towards an implementation in industry. Additionally, we present preliminary results of CIFT applied to a thermally driven flow with some similarity to Czochralski silicon crystal growth. Due to the low velocities in the order of 1 cm/s, the dynamic range of the measurement system has to be enhanced by about one order of magnitude in comparison with the continuous casting application.
