Abstract
A control system controls an amount of liquid filled into a container such as a bottle, a can or the like to be a predetermined amount in a precise and reliable manner. Liquid to be filled into the container is fed through a filling nozzle approximately up to a level somewhat higher than a predetermined target level. Then surplus liquid exceeding the predetermined target level is controllably ejected through an ejection nozzle piping having one end inserted into the container and opened at the target level. The surplus filled liquid is ejected through the ejection nozzle piping by suction or by pressure. When the ejection of the surplus filled liquid through the ejection nozzle piping begins, the pressure in the ejection nozzle piping changes from an initial valve. The end of ejection of the surplus filled liquid is detected by a pressure sensor disposed in the ejection nozzle piping. When the pressure sensor detects that the pressure in the ejection nozzle piping returns to the original pressure, a controller operates to stop a suction or pressure source.
