Abstract
A method for recognizing a capsule for preparing a drink, in particular a capsule containing powder for preparing the drink, arranged in a machine for preparing drinks provided with at least one measurement device (2, 3) adapted to measure the flow rate or pressure of liquid in a conduit (4) of the machine, and adapted to generate a signal associated with said flow rate or said pressure; wherein the recognition is performed as a function of said signal generated by said measurement device (2, 3) during a predetermined time interval, in particular when the pump (5) of the machine is active for preparing the drink; wherein the recognition is performed as a function of at least one feature of said signal, selected among mean value, variance, maximum peak, minimum peak and derivative.
