ABSTRACT. The present work is connected with a theoretical and experimental study of the application of two-component fibre-optic velocity sensors for diagnostics of liquid metal turbulent flo~. The above sensors have high spatial resolution (16)m~) and exhibit insignificant sensitivity to admixtures and the magnetic field; they could also be used for liquid metals in the presence of strong currents (::::10 A). The experimental data on the velocity fields and intensity of its pulsations in strongly nonuniform liquid metal magnetohydrodynamic flows are given. Dynamical errors of velocity measurements at a frequency of 200 Hz are negligible.
