A flowmeter for a medium includes two transducers displaced from each other in the direction of flow of the medium. The flowmeter contains an emitting device which emits acoustic signals in both directions through the medium using the transducer. The flowmeter also contains a processing device for determining information via the flow of the medium by monitoring the travel times of the acoustic signals received by the transducers. A part of the space between the transducers defines a flow path which includes a flow structure with at least one medium flow passage extending axially in the direction of the flow of the medium. The medium flow passage has damping devices which are located so that at least one asymmetrical noise propagation mode is damped. The damping device has a damping structure which extends substantially across the whole length of the media flow passage.
