Abstract
A flow sensor (1) comprising a flow channel (14) embedded in a base body (1′), a flow sensor element (13) adjacent to the flow channel (14) and a cover plate (12) covering the flow channel (14) and arranged on the base body (1′). The flow channel (14) is formed by an elastic sealing lip (15) which delimits the channel (14), running on and around an upper side of the base body (1′) lying opposite the cover plate (12) such that a seal is formed. This arrangement allows the formation of a sealed structure where a flow channel (14) with a level channel that avoids contamination and turbulence and has laminar current flowing through the flow channel (14).
