Measuring device for measuring the mass of a medium flowing in a line

A measuring device (1) for measuring the mass of a medium flowing in a flow line (2) as an aspirated air mass of an internal combustion engine, comprising a measuring element (21) bathed by a portion of the flowing medium and disposed in a flow conduit (10) of the measuring device (1) provided in the flow line (2), wherein the flow conduit (10) extends in a primary flow direction (19) between an inlet opening (12) that communicates with the flow line (2) and at least one outlet opening (13;

• 30) that discharges into the flow line (2) downstream of the inlet opening (12), in which the flow conduit (10) branches at a first dividing point (15), disposed between the inlet opening (12) and the measuring element (21), into a measuring conduit (20), in which the measuring element (21) is disposed, and a first bypass conduit (22), which bypasses the measuring element (21) in the primary flow direction (19), the measuring conduit (20) being radially offset from the inlet opening (12) relative to a longitudinal axis (3) of the flow line (2).
