Summary:The invention relates to a method for detecting foreign matters in a flowable medium, in particular with variable gas charge and preferably with free bubbles, comprising the following steps: determining a first time curve of a first measured value by means of a first measuring device, in particular by means of a Coriolis flow meter, and determining a second time curve of a second measured value by means of a second measuring device, in particular by means of a Coriolis flow meter; the physical density of the medium is determined; determining a second time curve of the second measured value by means of a second measuring device, in particular by means of a microwave sensor, for ascertaining the relative permittivity of the medium; -determining a temporal correlation between the first curve and the second curve; detecting a measured value pair of the first measured value and the second measured value; checking whether the detected pairs of measured values within a predetermined tolerance interval correspond to
