[origin: EP2172654A1] The aggregate has a suction inlet (4) provided on an inlet side of an impeller, and a pressure outlet (12) provided at an outlet side of the impeller. A vortex flow sensor and a guide element are arranged in a pipeline segment formed by the suction inlet and/or the pressure outlet. The guide element controls flow through the pipeline segment. The guide element is formed as a rib (22) inwardly protruding from an inner wall (26) of the pipeline segment. The rib extends in a flow direction (S) of a fluid along the inner wall.
