Abstract:
A device (1) for measuring at least one parameter, in particular an air mass flow, of a medium flowing in a line (2), in particular the intake air mass flow of an internal combustion engine, the device having a measuring element disposed in the line (2) and which the flowing medium circulates around, the flowing medium having regions of flow, at least one of the regions of flow contacting on the measuring element, the improvement wherein the device (1) has at least one protective screen (15, 95), disposed at least partially upstream of the measuring element (23) inside the line (2) and which deflects the medium flowing in a main flow direction (6) downstream of the protective screen (15, 95), so that dirt particles and liquid droplets entrained by the flowing medium are diverted downstream of the protective screen (15, 95) into a region of the flowing medium which does not contact the measuring element (23).
