21. A flow sensor comprising:
-
a conduit with fluid flowing through having a direction of flow; an obstruction projecting into said conduit for fluid to flow thereby, said obstruction generating vortexes downstream with respect to said direction of flow of the fluid flowing through said conduit; a measuring probe arranged in said conduit and measuring the vortexes, said measuring probe including a single membrane having a first side and an opposite second side ranged directly in the fluid flowing through said conduit, said single membrane being arranged downstream of said obstruction first fluid to flow by said first side and by said opposite second side with said first side and opposite second side being arranged to be deflected by the passing of the vortexes and said measuring probe including a measuring element arranged directly on said membrane for detecting a deflection of said single membrane.
