Abstract

A device for measuring at least one parameter, in particular of a volumetric flow, of a medium flowing in a line, in particular of the intake air volumetric flow of an internal combustion engine, includes at least one measuring element around which the medium flows. Constrictions, which do not uniformly constrict the cross-section of the line, do not produce any ring-shaped eddies that may be heard in the form of whistling noises.
