ABSTRACT:
The invention concerns a float-controlled flow-control devie for the outlet from a sewage system, especially a rain basin. The bearings for the pivots (7 & 8) that the float arm (4) and the shutter (2) rotate on are mounted on a displaceable structure (3). This makes it possible to vary the outflow volume to be controlled even when the device is in operation, and hence to control it remotely as well.
