Abstract
A measurement device for measuring the mass of a medium flowing in a line along a line longitudinal axis, in particular the intake air mass of an internal combustion engine. The measuring device has a measuring element around which the flowing medium circulates around. The measuring element is disposed in a measurement conduit that is provided in the line and extends along a measurement conduit longitudinal axis from an inlet opening to a deflection conduit. The deflection conduit leads to an outlet opening that feeds back into the line. The measurement conduit longitudinal axis is inclined in relation to the line longitudinal axis by a predetermined angle (.alpha.) so that the measurement conduit has a screened region that is disposed outside the parallel projection of the inlet opening along the line longitudinal axis. The measuring element is disposed in the screened region of the measurement conduit.
