Abstract

The behavior of the time of longitudinal relaxation T1 for a flowing liquid in the strong nonuniform magnetic field of the magnet polarizer of a nuclear-magnetic-resonance (NMR) flow meter is studied theoretically and experimentally. An increase in the nonuniformity of this field reduces T1. The magnitude and nonuniformity of the field have an optimum whose criterion is the signal/noise ratio in the recording scheme for the NMR signal and the weight and dimension characteristics of the instrument.
