Abstract

The invention relates to a device for determining at least one parameter of a medium flowing in a line, in particular the intake air mass of an internal combustion engine. The solid particles contained in the line act on a measuring element and influence a characteristic curve behavior of the measuring element, which is used to determine parameters of the flowing medium. In order to reduce the action of solid particles on the measuring element, the measuring element is disposed in a line or a tubular body downstream of a protective screen, and an element for influencing movement paths of the solid particles is disposed in the line, on an inner wall. By intentionally influencing the movement paths of the solid particles, their action on the measuring element is considerably reduced.
