Abstract

A measuring element which has been lengthening in the flow direction to provide a detachment zone which is shifted downstream from the region of the measuring resistor, so that end flow disturbances no longer affect the region of the measuring resistor, and adulteration of the measurement values is prevented. The measuring element is especially suitable for determining the throughput or flow rate of the aspirated air of mixture-compressing internal combustion engines.
