012 Open Loop Flow Control, Active

This active flow control device without any moving parts works solely by using the hydromechanical effects of the fluid. Constructed from corrosion-free stainless steel. Suitable for semi-dry installation at CSOs or CSO tanks.

This active flow control device without any moving parts works solely by using the hydromechanical effects of the fluid. Constructed from corrosion-free stainless steel and PVC, it is suitable for wet installation to control small to medium outflows.

Active flow control with very high flow resistance and large open cross section. Particularly suitable for controlling small discharges from rainwater storage basins.

Active flow control with high flow resistance, to control discharges from stormwater retention basins with permanent water level.

Flow control without mechanically moved parts with specific change of flow resistance by means of hydraulic effects. Particularly suitable for flood control reservoirs.

Active flow control device which operates by the ‘Bernoulli-Effect’. A flexible tensioned membrane hose is mounted on a flow control pipe so as to facilitate an almost constant flow. Corrosion free construction with no moving parts.

Active flow control device with a flexible membrane hose, which operates by the ‘Bernoulli-Effect’. For wet installation. Corrosion free construction with no moving components. Very steep characteristic curve.

Wear-free, corrosion-resistant, active control device without external energy to maintain a constant inflow rate into clarifier tanks and basins. Also very well suited for retrofitting.

Clarifier overflow in the shape of a pipe with bilateral inflow to maintain a constant inflow rate into clarifier tanks and basins. Wear-free, compact component, completely made of stainless steel.

Active flow control for limiting the inflow to a sedimentation chamber or a lamella settler: the open cross section under a spring steel sheet is varied by the differential pressure, thus producing a nearly constant flow. Operation under full backwater only.
