摘要：
A mass air flow sensor having a tubular probe body located within and aligned with a venturi passageway. The probe body has a channel therethrough connecting openings located at high and low pressure regions in the venturi passageway. The openings are configured to cause at least a 90 degree change in direction of air flowing therethrough from the venturi passageway to protect a fragile flow sensor in the channel from damage by suspended contaminants.
