Zusammenfassung:Known devices for measuring the mass of a flowing medium can be impaired in their measurement precision by fluid components carried along in the medium. The device (1) according to the invention has a ricochet body (25), which is disposed upstream of the measuring element (21) and is at least partially encompassed by an outer ring (30), where the outer ring (30) constitutes a section inside the outer ring (30) that tapers in the flow direction (18) in order to deflect fluid components, which are carried along in the flow (18), away from the measuring element (21) by means of the ricochet body (25). The invention is provided for measuring the mass of a flowing medium, in particular for measuring the intake air mass of internal combustion engines.
