1) A method to measure flow properties, including flow rates, regime and relative concentrations of phases in multiphasic fluids using Nuclear Magnetic Resonance Relaxation in the Rotating Frame, comprising:

• a. polarizing a plurality of Nuclear Magnetic Resonance active spins of a multiphasic fluid using a first magnetic field region, wherein the multiphasic fluid is composed by a plurality of phases, wherein the multiphasic fluid is herein flowing through the first magnetic field region, therefore creating a total macroscopic magnetization of the multiphasic complex fluid, wherein the total macroscopic magnetization is the result of adding all of a plurality of individual macroscopic magnetizations, each corresponding to the different phases of the multiphasic complex fluid;
• b. relaxing the plurality of individual macroscopic magnetizations of the phases of the multiphasic fluid in a first Nuclear Magnetic Resonance segment, wherein a plurality of radiofrequency pulses is applied to the multiphasic fluid, wherein the plurality of individual macroscopic magnetizations of the phases of the multiphasic fluid are relaxing in the rotating-frame condition, wherein the multiphasic fluid is herein flowing through the first Nuclear Magnetic Resonance segment, having a downstream end, wherein each macroscopic magnetization of each individual phase of the multiphasic complex fluid relaxes with different rotating frame relaxation rates, wherein applying the plurality of radiofrequency pulse sequences produce that the individual macroscopic magnetization of each phase of the multiphasic fluid at the downstream end of the second magnetic field region is, therefore applying the plurality of pulse sequences will encode an individual magnetization value for each of the phases in the total macroscopic magnetization for each of pulse sequences applied, wherein a degrees of contrast between phases are reached for each said radiofrequency pulse sequences;
• c. measuring the total macroscopic magnetization and fluid velocity for each of the rotating frame pulse sequences applied in a second Nuclear Magnetic Resonance segment, comprising a Nuclear Magnetic Resonance measurement module, wherein the Nuclear Magnetic Resonance measurement module permits measuring a plurality of magnetic resonance experimental parameters, wherein the Nuclear Magnetic Resonance measurement module is capable of acquiring a plurality of Nuclear Magnetic Resonance signals corresponding to the Nuclear Magnetic Resonance active spins of the multiphasic complex fluid, therefore multiphasic flow properties, weighted by the rotating frame relaxation profile and additional diffusion profile, are acquired and stored in a multidimensional data matrix;
• d. reading the multidimensional data matrix with a tangible computer-readable medium having stored thereon instructions that when read by a processor enable the processor to execute a method to evaluate multiphasic flow properties, weighted by rotating frame relaxation mechanism and diffusion profile.
