Mixed Level Control Gate
► Function
This equipment can be installed in canals or rivers. They allow to maintain a mixed regulation between their upstream and downstream levels and to compensate for inflows and outflows.
- They guarantee a minimum upstream level for lateral bypasses.
- They maintain a constant level downstream for flow adjustment or to allow on-demand operation.
- They guarantee a maximum level upstream in the cana
- They allow water to be stored in the canal or in lateral reservoirs to the canal.
- They allow simple and intuitive level regulation, allowing remote control of set points.
► Application
- Canal sections with on demand regulation.
- Control of inflow into reservoirs or lateral dams, controlling the downstream flow and bypassing the difference to the reservoir.
- Intakes in high-flow rivers, guaranteeing a constant and safe inflow, regardless of fluctuations in the river.
- Maximum level control in hydroelectric power plant head chambers.
- On demand flow control rate in a channel, operating in association with a water measurement structure.
- Reduction of canal changes, using the canal section itself to store water in times of excess and consume it in times of shortage or low user demand.
- Flood control, performing a controlled and autonomous regulation of the flood to areas prepared for this purpose, and draining, once the emergency is over, also in an autonomous and controlled way, the volumes stored in those areas.
