| Zusammenfassung: | The present invention relates to a device for measuring at least one parameter of a medium flowing in a line, particularly the intake-air volume of an internal combustion engine. Liquid particles contained in the line act upon a measuring element and influence a characteristic curve of the measuring element which is used to determine parameters of the flowing medium. The characteristic curve of the measuring element can be changed disadvantageously by solid-matter particles. According to the present invention, to reduce the action of solid-matter particles on the measuring element (
23
), a protective grating (
15
) is proposed in which side walls (
36
) of channels (
43
) of the protective grating (
15
) form various angles of intersection with the flow direction (
6, 12
). Solid-matter particles are thereby diverted into a path of motion (
53
) around the measuring element (
23
). |
