本发明公开了一种新颖的液面控制系统，特别是用于控制在敞开渠道中流动的水面高度。该液面控制系统包括具有挡板部分(3)的闸门，该挡板部分连接于杠杆部分(5)。该挡板部分能够绕第一枢轴点(8)转动并包括第一重块。该系统还包括框架(1)，该框架相对于该挡板部分固定。连接件(11、12、13)相互连接于挡板部分和杠杆部分，并且在不同于第一枢轴点(8)的第二枢轴点(10)连接于该框架。在渠道中的流动条件改变时，该系统以两种方式运行：该杠杆部分和该挡板部分的绝对运动，(ii)该杠杆部分和该挡板部分之间的相对运动。还公开了一种包括液面控制系统的流体处理系统和一种用于控制流体流的液面的方法。 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 portion 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.
