Water needs a future! Features: Constant water level = constant impoundment depth for volume activation No energy source required for propulsion or control Exakt water level regulation - control hysteresis of 3 cm (proportional controller) Detention/ Retention basins, Treatment plants Pump stations, Lift stations Locks, reservoirs, water courses Hydro-electric plants Flood control Upstream headwater control means that the ASK-Weir is not effected by varying tailwater levels, even during backwater situations. Retains floating solids throuhg under flow for constant water surfaces System based flood protection up to the impoundment level Automated float controlled gate weir to maintain the impoundment depth and to activate additional volume Operational safety, even with large flows of up to 30 m3/s per Weir Corrosion resistant (durable) structure made of either stainless steel or GFK Constant impoundment depth to activate volume Backwater and flood control Repells floating solids WE OFFER: Design support, sizing and dimensioning, providing of CAD-files, Weir Designer at Service Center at www.systemtechnik.net Facility support and performance of service and maintenance tasks We would love to advice you and create a noncommital proposal for you, customized to your individual needs Meschede HST Hydro-Systemtechnik GmbH Sophienweg 3 · D-59872 Meschede Tel. +49-2 91-99 290 Fax +49-2 91-76 91 e-mail: [email protected]

ASK-Weir This is how the ASK-Weir works: The ASK Weir opens and closes controlled by the float. After the impoundment depth is reached, water enters the float chamber. The resulting float buoyancy opens the gate proportional to the incoming flow. This way, the impoundment depth is maintained at a constant level at every possible flow. Therefore, the retention volume is utilized to the fullest. Activation and better use of retention volumes Smaller, more compact structures possible due to high hydraulic throughput Floating solids retention and excellent deposit prevention through underflow design...
