A flow sensor for measuring the flow of a gaseous or liquid medium with a sensor housing in which, between an inlet channel and an outlet channel, a flow channel extends that comprises a main channel and a measuring channel that is arranged parallel to the main channel. At least one main channel choke point is arranged in the main channel, and the measuring channel comprises a sensor element for measuring the flow. A measuring channel choke point in the measuring channel on the inlet and/or the outlet side, is arranged with the main channel choke point having at least one passage and the measuring channel choke point having a passage, both passages being of identical shape and extending parallel to each other in the flow direction.
