Vorrichtung zur Messung der Masse eines strömenden Mediums

摘要

Known devices for measuring the mass of a flowing medium present a measuring element accommodated in a measuring connector piece, whereby a flow straightener provided with bars is located downstream the measuring element. In order to produce bars easily and and fit them precisely, a support ring (22) is provided. Said ring supports bar (21) so that two parts, a flow straightener (20) and a support ring, (20) are available, wherein the rim of the ring (25) of the measuring connector piece (26) is flattened down thereby ensuring permanent fastening of the flow straightener (20). The device is designed to measure the mass of a flowing medium, especially in order to measure the mass of intake air in internal combustion engines.
