Fluid medium i.e. intake air mass, parameter e.g. pressure, determining device, for motor vehicle, has flow channel formed such that flow channel is passed into bypass-part, where channel wall is provided in region with flow grooves
Fluid medium i.e. intake air mass, parameter e.g. pressure, determining device, for motor vehicle, has flow channel formed such that flow channel is passed into bypass-part, where channel wall is provided in region with flow grooves
The device has a flow channel (126) with a flow channel wall held in a bypass-part (142) i.e. plug-in sensor, which is brought in alignment to a main flow direction in a fluid medium. The flow channel is formed such that the flow channel is passed into the bypass-part by the fluid medium. The flow channel wall is provided in a region with flow grooves (314). A sensor unit i.e. hot film air mass sensor, is mounted in a measuring channel (138). A main flow channel (128) and/or the measuring channel are provided with the flow grooves.
