Summary:In devices for measuring the mass of aspirated air of an internal combustion engine, for instance, via a line, it is already known to provide a tubular body inside this line and to provide a temperature-dependent measuring element inside the tubular body. In order that dirt particles and liquid droplets entrained by the aspirated air will be kept away from the measuring element, in accordance with the invention, a protective screen is disposed inside the tubular body, upstream of the measuring element; the screen extends in inclined fashion in the flow direction, and dirt particles and liquid droplets are deposited on it and carried to a downstream end of the protective screen, so that via an outflow opening they can reach the inner conduit wall of the tubular body and be made to bypass the measuring element.
