Patent ID: 6915682

Claim:
A device for determining at least one parameter of a flowing medium in a line, comprising: at least one measuring element circumflowed by the flowing medium; and a bypass channel including: at least one intake port connected to the line; at least one exit opening out into the line; a measuring channel in which the at least one measuring element is situated; and an input region situated downstream after the at least one intake port, wherein: the flowing medium subdivides completely in the input region into a first partial flow and a second partial flow, the first partial flow flows completely into the measuring channel, the second partial flow flows completely through at least one separation opening, the at least one intake port, in an axial direction that runs perpendicular to a main flow direction, includes an upper boundary edge that is closest to the at least one measuring element, an upper plane, which lies perpendicular to the axial direction and parallel to the main flow direction, runs through the upper boundary edge of the at least one intake port, and in the bypass channel the at least one separation opening is present, which in the axial direction is farther removed from the at least one measuring element than the upper plane.
