Vorrichtung zur Messung der Masse eines strömenden Mediums

摘要

Known instruments for measuring the mass of a flowing agent comprises in a connecting sleeve a measuring member, upstream of which a flow straightener with a grate is provided. In order to simplify the manufacture and the assembly of the grate (21) and to enable its accurate installation on the flow straightener (20), said grate (21) includes single-piece spring elements (30) which can be elastically distorted during the assembly process and are capable of reliably holding the flow straightener (20) and the grate (21) due to an elastic closure with a locking structure (33, 35), provided on said flow straightener (20). The inventive instrument is intended to measure a flowing agent, including the inlet air mass in internal combustion engines.
