Bottle filling machine with sensor and method thereof

A method of adjusting an amount of liquid that flows into a plurality of containers, the method comprising:

• transporting the containers by a carrier;
• flowing liquid respectively through a plurality of filling valves into the containers;
• controlling an amount of liquid that flows into the containers while the containers are transported by the carrier, the amount of liquid being controlled by electrically opening the plurality of filling valves for a predetermined period of time;
• conveying the containers along an exit feed path after the containers have been filled;
• sensing a level of liquid in the containers while the containers are on the exit feed path to produce signals which represent the level of liquid in the containers, respectively;
• adjusting the predetermined period of time that each of the plurality of filling valves remain open for subsequent fillings based on the signals;
• and
• maintaining the filling valves open for a period of high flow and for a period of low flow,
• wherein the adjusting includes adjusting the time the valves stay open for the period of high flow based on the signals and adjusting the time that the valves stay open for the period of low flow based on the signals, and
• wherein the level of liquid in multiple containers filled by one of the filling valves is sensed before adjusting the time the valves stay open for the period of high flow and the period of low flow.

A filling apparatus, said filling apparatus comprising:

• a carrier for transporting containers;
• means for electrically controlling a period of time that liquid flows into said containers, while said containers are transported by said carrier;
• an exit feed path which conveys said containers after said containers have been filled;
• and
• means for sensing a level of liquid in said containers while said containers are on said exit feed path, such that said means for sensing produces a signal which represents said level of liquid,
• wherein the means for electronically controlling controls a period of time that liquid flows into said containers during a period of high flow and during a period of low flow, and adjusts the period of time for the high flow based on the signal and adjusts the period of time for the low flow based on the signal, and
• wherein the level of liquid in multiple containers is sensed before adjusting the time the valves stay open for the period of high flow and the period of low flow.
