Flow converter

摘要

A flow converter for an air flow rate meter, especially for an intake conduit of an internal combustion engine, includes a plastic flow rectifier for converting an aspirated air mass into a laminar air flow moving in a given flow direction. The flow rectifier includes a honeycomb body and a ring integral with the honeycomb body. The honeycomb body has a surface disposed at right angles to the given flow direction and the ring protrudes out of the surface. A grid is permanently secured to the flow rectifier for generating microscopic eddies in the laminar air flow.
