ABSTRACT:
An apparatus for detecting and maintaining the level of a liquid in a container filling machine having a rotatable filler bowl includes a float disposed within the liquid in the bowl and having a permanent magnet disposed within the float body. A liquid level indicating bar is mounted within the bowl and is formed from a magnetically responsive material so that vertical movement of the float results in a vertical movement of the liquid level indicating bar. An infrared photo detector is provided for detecting the position of the liquid level indicator and controls are provided for increasing or decreasing the rate of flow of liquid into the bowl depending on the detected level of the liquid.
