Abstract
A method for operating a nuclear magnetic flowmeter for determining the flow of a slug flow medium flowing through a measuring tube, with which 'tuning' parameters and 'matching' parameters are set for a slug zone a film zone, reflected power is measured over time. If the reflected power in a system set for slug zone is low for the slug zone and high for the film zone and if the reflected power in a system set for film zone is low for the film zone and high for the slug zone, relative dwell time of the slug zone and the film zone in the RF coil and the relative frequency of the slug zones and film zones in the flowing medium are determined using the reflected power with a jump in the value of the reflected power from a high value to a lower value used to trigger measurement initiation.
