Abstract:
A measurement device (1) for measuring mass flow of an intake air medium flowing in a line (2) along a line longitudinal axis (3) of said line (2) of an internal combustion engine, said device including a measurement conduit (9) provided in said line (2), said measurement conduit having an air inlet opening (10), a measuring element (12) around which the flowing medium circulates and which is disposed in the measurement conduit (9), a deflection conduit (11) extending from said measurement conduit (9) and having an outlet opening (13), said measurement conduit extends along a measurement conduit longitudinal axis (19) from the inlet opening (10) to the deflection conduit (11), said deflection conduit leads to the outlet opening (13) that feeds back into the line (2), the measurement conduit longitudinal axis (19) is inclined in relation to the line longitudinal axis (3) of the line (2) by a predetermined angle (.alpha.) so that the measurement conduit (9) has a screened region (20) that is disposed behind the inlet opening (10) along the line longitudinal axis (3), and the measuring element (12) is disposed in the screened region (20) of the measurement conduit (9).
