Abstract: Method of determining a velocity profile of a fluid flowing through a conduit, the method including applying a saturation pulse on spins of magnetic field-sensitive nuclei in the fluid, measuring a signal of the fluid to determine position of the magnetic field-sensitive nuclei, the measurement carried out at a recovery time ‘TR’ and at a distance ‘d’ within the conduit, determining within the conduit a radial distance ‘r’ characterized by a local minimum in the measured signal, wherein the radial distance ‘r’ is measured from the center of the conduit, and determining a velocity profile of the fluid at the radial distance, based on the magnetic field-sensitive nuclei.
