A method of the relaxation time measurement in a flowing sample, based on the comparison of the amplitudes of nuclear magnetic resonance (NMR) signals observed from the reference and tested flowing sampleswas represented. The inductive and optical methods of NMR signal detection in the flowing sample were compared. The levels of NMR signal (10000 Hz-1/2) and the Hanle magnetometers signal-to-noise ratio (3500 Hz-1/2) were calculated and the possibility of the NMR signal detection with the small-size Hanle magnetometer was demonstrated. Additionally, the absence of a magnet-analyzer and the ability to measure both longitudinal and transverse relaxation time with high accuracy was demonstrated.
