Air flow meter for combustion engine

摘要

The flow meter has an air flow module (20) with an integrated flow detector (7,8) and drive circuit (10). The detector (7,8) measures the air flow in the combustion engine. The drive circuit (10) is connected to the flow detector (7,8) to output a signal corresponding to the measured air flow. An air flow measurement housing forms an air inlet (5,6) for the combustion engine. The air flow module (20) is built into the housing so that the air flow detector (7,8) can be arranged in the inlet (5,6). The housing has an end connected in flow technology to an air filter element (3). The housing also includes a tube (2) with a module fastening part connected to the other end of the housing. The cross-section of a connection section (4) between the housing and the tube (2) is perpendicular to the air flow of the smallest cross-section in the tube.
