Analysis and control of fluid flows, often subsidiary to industrial design issues,require measurements of the flow field. For classical transparent fluids such aswater or gas a variety of well-developed techniques (laser Doppler and parti-cle image velocimetry, Schlieren optics, interferometric techniques, etc.) havebeen established. In contrast, the situation regardingopaque liquids still lacksalmost any commercial availability. Metallic and semiconductor melts oftenpose additional problems of high temperature and chemical aggressiveness,rendering any reliable determination of the flow field a challenging task. Thisreview intends to summarise different approaches suitable for velocity mea-surements in liquid metal flows and to discuss perspectives, particularly inview of some recent developments (ultrasound, magnetic tomography).Focus-ing mainly on local velocity measurements, it is subsequently distinguishedbetween invasive and non-invasive methods, leaving entirely aside the acqui-sition of temperature, pressure, and concentration, for which [1] may serve asa comprehensive reference.
