Abstract

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, has a part provided for introducing into the line, having at least one measuring channel for conducting at least one subflow of the medium flowing in the line, and having at least one measuring element situated in the measuring channel for determining the at least one parameter, in which the part may be introduced into the line with a predetermined orientation with respect to the medium flowing in the line in the main flow direction. A channel structure is formed in the part, the channel structure having an inlet area for the entry of a substream of the medium into the channel structure as well as at least one measuring channel branching off from the inlet channel, the measuring channel having an outlet opening that opens toward the outside of the part, the inlet area having a discharge zone that has a discharge orifice on a first lateral wall of the part, which opens toward the environment, and the discharge zone is closed on one second lateral wall diametrically opposite the first lateral wall.
