Abstract
A device for measuring the mass of a flowing medium having a measurement element accommodated in a measurement support, and a flow rectifier with a grid provided upstream of the measurement element. For simple production and accurate alignment of the grid, a carrier ring is provided, which carries the grid, so that there are two parts, that is, a flow rectifier and a carrier ring with the grid; by crimping over an annular edge of the measurement support, a durable fastening of the flow rectifier is accomplished. The device is intended for measuring the mass of a flowing medium, of aspirated air in internal combustion engines.
