Zusammenfassung:	THE INVENTION RELATES TO A SINGLE-JET LIQUID METER (20) COMPRISING A BODY (22) IN WHICH A MEASUREMENT CHAMBER (28) OF SUBSTANTIALLY CYLINDRICAL SHAPE IS DISPOSED, THE CHAMBER BEING FITTED WITH A SPINNER (30) HAVING A LONGITUDINAL AXIS XX''' AND PROVIDED WITH BLADES (36), A LIQUID FEED TUBE (24) AND A LIQUID DISCHARGE TUBE (26) CONNECTED TO SAID BODY AND IN ALIGNMENT ON AN AXIS YY''' THAT INTERSECTS SAID AXIS XX''' PERPENDICULARLY, A HOUSING (54) DISPOSED IN SAID BODY AROUND THE PERIPHERY OF THE SPINNER AND INCLUDING AT LEAST TWO SLOTS (58, 60) RESPECTIVELY PLACED FACING THE FEED TUBE AND THE DISCHARGE TUBE, SAID SLOTS BEING DESIGNED TO INJECT AND EJECT THE LIQUID FLOW IN INCLINED MANNER RELATIVE TO THE ALIGNMENT AXIS OF THE TUBES, THE METER BEING CHARACTERIZED IN THAT AT LEAST ONE SLOT (58; 74) IS PLACED FACING THE FEED TUBE AND OFFERS TO THE FLOW OF LIQUID COMING FROM SAID TUBE A SHAPED SURFACE (62; 72; 75) THAT PROGRESSIVELY INCREASES THE SPEED OF SAID FLOW.
