Meßvorrichtung zum Messen der Masse eines in einer Leitung strömenden Mediums

摘要

The invention relates to a measuring device (1) for measuring the mass of a medium, especially the induction air mass of an internal combustion engine, flowing in a line (2). Said measuring device comprises a measuring element (21) around which the flowing medium flows. The measuring element is arranged in a flow channel (10) of the measuring device (1), said channel being provided in the line (2). The flow channel (10) extends along a main direction of flow (19) between an inlet opening (12) which is connected to the line (2) and at least one outlet opening (13) which flows into the line (2) downstream from the inlet opening (12). According to the invention, the flow channel (10) branches into a measuring channel (20) in which said measuring element (21) is arranged and into a first bypass channel (22) which bypasses the measuring element (21) in the main direction of flow. The flow channel branches at a first separating point (15) which is arranged between the inlet opening (12) and the measuring element (21).
