Abstract
A fluid level control system, particularly useful for controlling the level of water flowing in an open channel. The fluid level control system includes a gate having a flap port on interconnected to a lever portion. The flap portion is rotatable about a first pivot point. The system further includes a frame which is fixed with respect to the flap portion. A linkage interconnects the flap portion and the lever portion, and is connected to the frame at a second pivot point different than the first pivot point. Under changing flow conditions in the channel, the present system operates by both: (i) absolute movement of the lever portion and the flap portion, and (ii) relative movement between the lever portion and the flap portion. A fluid treatment system and a method for controlling the level of a flowing fluid may also use such a fluid level control system.
