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. Said transmitting transducer (11) also produces an additional variable magnetic field in the area of the object and an additional ultrasonic wave is produced in said area by means of the interaction of the variable magnetic field with a static or quasi-static magnetic field, said other ultrasonic wave is superimposed on the first ultrasonic wave such that an amplitude of a resulting wave in the direction of the receiving transducer (12) is increased and is reduced in the direction away from said receiving transducer (12). Preferably, the first and the second magnetic fields are produced by two high frequency bobbins (18, 19) of the transmitting transducer (11). The invention also relates to a device for carrying out said inventive method.

Pipe for transporting a medium and method for manufacturing a pipeline
A pipeline has a first pipe and a second pipe welded together by a weld seam, wherein the first and second pipes each have an inner side with a lining section of plastic material for protecting an inner side of the pipeline. The lining sections end at a spacing from the weld seam. The lining section of the first pipe abuts the lining section of the second pipe such that by an undercut provided on at least one of the lining sections a fill space is formed in a circumferential direction of the pipeline.
The invention relates to a method for constructing and/or manufacturing a water sports device (2) which has a modular structure comprising a floating body (4).
