Device for regulating parameter of flowing medium in line in mainstream direction, particularly determination of air mass stream in sucking in tract of internal-combustion engine, has line part visual art of line passage

摘要

The device (110) has a line part (114) visual art of a line passage and a sensor unit with a bypass unit (128) rising up into the line passage. A channel structure is formed with a sensor element in the bypass unit. A projection (144) is provided having a vortex element (160), which is out-arranged to form longitudinal vortices in the medium.
