Abstract

A device for measuring at least one parameter of a medium flowing in a line, in particular the intake air mass of an internal combustion engine in which fluid particles and solid particles in the line influence a characteristic curve behavior of a measuring element which is used to determine a parameter of the flowing medium. A protective screen according to the invention deflects fluids and solid particles away from the measuring element in such a way that they are conveyed against an inner wall of the line. In addition, the device stabilizes the flowing medium by generating longitudinal eddies in a flow direction.
