Abstract
An apparatus for control of a liquid level, especially water level, comprising a partition (10) arranged in a drain channel (24) and having an upper edge (12) which serves as overflow. At its lower or bottom edge (14) opposite the upper overflow edge (12) the partition (10) is supported for swinging (axis of rotation 16) at the bottom of the drain channel (24). Extending obliquely upwardly from the bottom of the drain channel (24), away from the water end (18), the partition (10) is held by a level control means (20).
