A dual-plane, dual-component ultrasound array Doppler velocimeter for investigating transient complex flow phenomena in liquid metals is presented. It utilizes four sensor arrays consisting of 25 single element transducers along a line of 67 mm. The system combines a spatial resolution of approx. 3 mm with a temporal resolution of up to 30 Hz using electronic beam traversing and time division multiplex. The modular realization of the measurement system allows flexible sensor configuration, e.g. four planes can be measured with one velocity component, two planes with two components or two lines with three components. Those capabilities are demonstrated by measurements in a magnetically stirred metal melt at room temperature.
