A device for measuring the mass of a medium flowing in a line, especially the aspirated air mass on an internal combustion engine, comprising a flow tube, which is disposed in the line. A measuring element around which the flowing medium flows is disposed in the flow tube. The medium flows from the line into the flow tube at an inlet opening and out of the flow tube into the line at an outlet opening. An outlet end face of the flow tube surrounding the outlet opening has structural grooves, which extend with a radial directional component with respect to a longitudinal axis of the flow tube.
