The device comprises an impeller, a diffuser upstream from the impeller and detecting means for the impeller ( 46 ). The diffuser ( 41 ) has a core ( 42 ), a ring-shaped peripheral portion ( 43 ) and one or more separators ( 45 A, 45 B) extending between the core ( 42 ) and the peripheral portion ( 43 ) and developing so as to define helical channels for fluid passage ( 44 A, 44 B).
