Аннотация
An upgrade of the structure of magnetic resonance flowmeter–relaxometer is proposed to improve the metrological characteristics. The improved structure of the magnetic resonance flowmeter–relaxometer is based on the modulation of static magnetic field Н0 by ac magnetic field in the region of the nutation coil. The experiments show that the measurements of liquid flow q in the proposed regime make it possible to eliminate the effect of measurement errors related to variations in amplitude and phase of the NMR signal inverted by 180° under rapid variations in quantity q and increase the measurement dynamic range of quantity q by 30%.
