Mass flow rate measuring device for IC engine air intake has surface normal to measuring surface of measuring element projecting into flow path provided with component in gravity force direction

摘要

The mass flow rate measuring device has a measuring element (16) projecting into the flow path of the flow medium fed along the flow line for the IC engine air intake. The surface normal (F) to the measuring surface (18) of the measuring element has a component in the gravity force direction (g), the measuring surface provided by a thin-film resistance layer, extending parallel to the horizontal flow of the flow medium. An Independent claim for an IC engine air intake system with a mass flow rate measuring device is also included.
