Claim 0:
1. A system, comprising:
a fluid dispenser;
a distance sensor;
a plurality of electromagnetic radiation emitters and receivers;
a user interface configured to receive a desired percentage of the height of the container to be filled with liquid; and
a controller electronically connected to the distance sensor, the plurality of electromagnetic radiation emitters and receivers, the user interface and the fluid dispenser;
wherein the controller is configured to:
determine the height of the container from the plurality of electromagnetic radiation emitters and receivers;

wherein determining the height of the container comprises:
switching each emitter on and off among the plurality of electromagnetic radiation emitters and performing the reading of the luminous intensity from a receiver corresponding to the emitter switched on; determine the height of the container based on at least one receiver that had luminous intensity readings within an individual reference range;
determining the height of liquid in the container from at least one measurement of the distance sensor;
determining a desired height of liquid in the container based on the height of the container and the desired percentage of the height of the container to be filled with liquid;
comparing the height of liquid in the container and the desired height of liquid;
controlling a flow of liquid from the dispenser to the container based on the height of liquid in the container and the desired height of liquid; and
perform a calibration of the receivers by reading the readings presented by the receivers and subtracting a safety margin from the reading of each one of them to obtain individual reference values, wherein the individual reference values automatically determine individual reference ranges with a safety margin for each receiver.
