The NMR flow‐imaging system is capable to determine quantitative flow‐ and fluid parameters. The parabolic velocity profiles for Poiseuille flow of water and the constant velocity spectra in one‐ and two‐tube systems show quantitative agreement with theoretical considerations. The relation of the maximum velocities in the two‐tube system and the velocity distribution function turned out to be characteristic features to distinguish quantitatively the flow properties of Newtonian and non‐Newtonian fluids.
