TRACER-LABELLING NUCLEAR-MAGNETIC FLOWMETER Russian patent published in 1995 - IPC

Abstract SU 1621689 A1

FIELD: liquid flow metering technology. SUBSTANCE: liquid passed through piping is polarized in polarizer, label is imposed on it in tracer coil due to inversion of nuclear magnetic moment, nuclear magnetic resonance signal is recorded in analyzer coil. Pulse-width modulator shapes pulses whose length is inversely proportional to flow rate. EFFECT: improved measurement accuracy, particularly at ends of flow measurement range. 2 dwg
