Abstract
A method for determining a liquid portion of a flowing medium with a nuclear magnetic flowmeter includes: generating a gradient magnetic field in a measuring tube volume of the flowmeter; exposing the medium to the gradient magnetic field and a magnetic field generated by a magnetizing device of the flowmeter; generating and irradiating an excitation signal into the magnetized medium for exciting nuclear magnetic resonances therein; measuring nuclear magnetic resonances excited by the excitation signal in the magnetized medium as a measuring signal; determining frequencies of the nuclear magnetic resonances in the measuring signal; assigning the determined frequencies to positions along a first gradient direction in the measuring tube volume; assigning the nuclear magnetic resonances at the positions to liquid and gaseous portions of the medium; and determining a liquid portion of the medium in the measuring tube volume from the positions of the nuclear magnetic resonances.
