Direct measurement of effective electro conductivity are performed in a nonstationary turbulent flow of liquid gallium, generated in a closed toroidal channel. The peak level of the Reynolds number reached Re ≈ 106, what corresponds to the magnetic Reynolds number Rm ≈ 1. The conductivity of the liquid metal was determined measuring the phase shift between sinusoidal voltage and current in the RLC-circuit, the inductance of which was made by the toroidal coil embracing the channel. The maximal deviation of electrical conductivity from its ohmic value reaches about 1%.
