Abstract
A method for distinguishing between the presence of a foreign body and a gas bubble in a flowable medium in a pipeline or a container includes evaluating received microwave signals, wherein mechanical vibrations are introduced into the medium by means of which a gas bubble present in the medium is set into vibration. A gas bubble is detected only in the event that when mechanical vibrations are introduced and the received microwave signals or the value derived therefrom is/are modulated; otherwise, a foreign body is detected. Also disclosed is a system which is suitable for carrying out the method according to the present disclosure.
