A milking system, including a milk line; a vacuum arrangement; a milking unit; a pulsator, configured to adjust pulsation ratio and pulsation rate of fluid pressure at two distinct levels; a receiver connected to the milk line, and also connected to the vacuum arrangement; a milk meter; and a processing device communicatively connected to the milk meter and the pulsator; the processing device is configured to, repeatedly during the milking session obtain and compare a milk flow measurement with a low milk flow limit; and, when the milk flow measurement is lower than the limit apply a low pulsation rate and a first pulsation ratio, wherein the D-phase is longer than the B-phase; or otherwise apply a high pulsation rate and a second pulsation ratio, wherein the B-phase is longer than the D-phase.
