Abstract

A circuit configuration for regulating the filling and refilling of containers with liquids, such as a carbonator vessel, and comprises a liquid container and an electronic circuit for reading the liquid level in the container at a single level and generating a level signal corresponding to the liquid level sensed, and in the event the level falls below a predetermined level, causes a flow regulator controlled by a timer to provide a refilling with an overshoot so as to permit the liquid level to rise to a second predetermined level above the first predetermined level so that the volume of the head space and pressure within the container is held substantially constant.
