Mass flow sensor device with a flow guiding channel

A mass flow sensor device for at least a partial arrangement in a main channel (2) displays a mass flow sensor (1), in which a mass flow flows in the main direction of flow. The mass flow sensor (1), which has a bypass channel (7) which displays an inlet section (9), can send current via the mass fl...

Zusammenfassung:A mass flow sensor device for at least a partial arrangement in a main channel (2) displays a mass flow sensor (1), in which a mass flow flows in the main direction of flow. The mass flow sensor (1), which has a bypass channel (7) which displays an inlet section (9), can send current via the mass flow from the main channel (2) into the bypass channel (7). Furthermore, at least one mass flow sensing element (17, 19) is proposed, by means of which a characteristic variable can be registered for the mass flow in the main channel (2). A flow guiding channel (23) is proposed which has an inlet cross section (25) running perpendicular to the main direction of flow (3) and which features a maximum one third overlap relative to the inlet cross section (25). The inlet cross section (25) is essentially arranged in the middle of the main channel (2). The flow guiding channel (23) is designed and arranged in such a way that it leads the flow medium at least partially to the inlet section (9) of the mass flow sensor (1),
