Abstract
An air flow meter that includes a filter or flow rectifier disposed in a retaining aperture of a collar in a bypass channel such that a second end face of the filter rests against one end of a slide-in member in which a resistance element is held in position without any edges that disturb the air flow in the remainder of the bypass channel. The air metering device is designed to be used to measure the air sucked into an air intake tube of an internal combustion engine.
