The present invention relates to a method for dispensing a liquid to fill a container (4) up to a predetermined liquid level. The invention also refers to a dispenser capable of achieving such a method. A method for dispensing a liquid (2, 22) in a container (4) according to the invention is characterized by a combination of the following steps: (a) place a container (4) beneath an outlet (6, 26a, 26b) of at least one fluid dispensing conduit (3, 23a, 23b); (b) arrange a pair of electrodes (9, 13, 9a, 13a, 29, 213) in a position where they are adapted to face the this liquid (2), electrically isolated from the same, (c) starting the flow of liquid through the the conduit (3); (d) measuring the effective impedance (Z) between the first and second electrode (9, 13; 9a, 13a, 29, 213) during the liquid flow; (e) compare the actual impedance (Z) with a reference impedance (Z1); and (f) interrupting the liquid flow when a predetermined condition between the effective impedance (Z) and the reference impedance (Z1) is achieved. |
