The HydroVortex flow controller allows the flow rate at a given height to be controlled but does not allow very precise flow rate regulation at all water heads.
Even so, the vortex effect ensures far better flow rate regulation than just a calibrated outlet.
It can regulate flow rates even with significant water heights (> 6 m):
- 5 to 500 l/s for HydroVortex - 18 to 1000 l/s for HydroDB.
