Abstract
A method for operating a nuclear magnetic flowmeter for determining the flow of a multi-phase medium flowing through a measuring tube that is suitable for media exhibiting 'phase slip' with which the characterization of the gaseous phase is simplified, is achieved by a pulse spoiling the magnetization at least in the direction of the magnetic field or a pulse sequence spoiling the magnetization in the direction of the magnetic field being emitted by a coil-shaped antenna, particularly in combination with dephasing gradients, and then, after a waiting time t, a nuclear magnetic measurement is carried out in that the medium is excited with excitation pulses by the coil-shaped antenna and the measuring signals generated by the excitation in the medium are detected.
