    • A device for determining at least one parameter of a medium flowing in a line, in particular for determining the air mass flow rate in the intake manifold of an internal combustion engine, which include a line component 3 and a sensor device 1 having a bypass part 6, are known. To prevent separation of the flow at the sidewalls of the bypass part, it is provided that a flow diversion element 2 be positioned in the line component 3 upstream from the bypass part 6 with respect to the main flow direction 18 and have at least one diversion surface 20 facing the main flow direction 18, which, starting from an apex line 25 located at a distance from the bypass part 6, curves evenly on both sides toward the two sidewalls 16, 17 so that the ends 38 of the diversion surface 20 facing away from the apex line are aligned with the sidewalls 16, 17.
    • 一种用于确定在线中流动的介质的至少一个参数的装置,特别是用于确定内燃机的进气歧管中的空气质量流量,其包括线路部件3和具有旁路部分的传感器装置1 6,已知。 为了防止在旁路部分的侧壁处的流动分离,提供了分流元件2相对于主流动方向18定位在旁路部分6上游的管线部件3中,并且具有至少一个转向 面向主流动方向18的表面20,其从位于距离旁路部分6一定距离处的顶点线25开始,在两侧均匀地朝向两个侧壁16,17弯曲,使得转向表面20的端部38面向 远离顶点线与侧壁16,17对齐。
