ABSTRACT:
The gate of the present invention regulates the level of a downstream reach (4) by means of a sector-shaped plate (1) carried by a frame (6, 7) that oscillates about a axis (5) and that also carries a float (8) dipping into said reach. Substantially neutral equilibrium is obtained at a reference level by raising the center of gravity above the oscillation axis, and the reference level is adjusted by transferring water between two longitudinally offset tanks (11, 13). The invention is particularly suitable for irrigation networks.
