This paper presents the mathematical algorithm results of a test that determines the fluid flow velocity vector (direction, intensity and orientation), based on voltages measured on a multi-channel hot-wire anemometer. Since dependence of voltage on the constant temperature hot-wire anemometer is a non-linear function of velocity, inverse function is also non-linear and has several mathematically correct solutions. The mathematical algorithm successfully determined the fluid velocity vector if the range of instrument operation is limited to the values of spherical angles
