Patent number: 9664543Abstract: The invention relates to a method for determining the flow or the flow rate of a medium in an electrically conductive object, in particular a pipe (1) or a pipeline, through which a medium flows. At least one ultrasonic wave (16) is produced by means of a transmitting transducer (11) in the object and is injected into the medium as a longitudinal wave (8) on an inner side of the object, and an ultrasonic signal, coming at least partially from the longitudinal wave (8), is received by the receiving transducer (12), at a spatial distance from the injection point and is used to evaluate the flow or the flow rate. Said transmitting transducer (11) produces, preferably in the absence of an acoustic coupling with the surface of the object, a first variable magnetic field in an area close to the surface of the object, in particular metallic, and a first ultrasonic wave is produced in said area by means of the interaction of said variable magnetic field with a static or quasi-static magnetic field.Type: GrantFiled: September 27, 2013Date of Patent: May 30, 2017Assignee: Rosen Swiss AGInventors: Evgeny Twerdowski, Carsten Heinks
