Overflow weir type: KOS I en KOS II

Application

KWT weirs are very varied and are used in surface, sewage and process water systems. The KOS system
allows a constant adjustment of the upstream water level.

Operation

The KOS weir penstock can be used to keep the upstream water level at a desired level, and can be very
accurately adjusted between it’s upper and lower limit. The KWT weir penstock can be supplied with a single spindle (KOS I- up to 1500 mm width) or a double spindle (KOS II- prevents jamming). The KOS II can be used on wider structures, removing obstructions from the flow and also reducing the build height of the structure. The KOS weir penstock can also incorporate a V notch if required. This will ensure that the weir can be used for flow rate calculations where small quantities of water discharge are involved.A double weir penstock type DKOS, is also available for ultimate control. This ncorporates a KOS penstock, operating against a second moving plate. The KOS (top plate) allows the water level to be adjusted at the top, whereas the bottom plate can be lifted to allow water to
flush at the bottom of the structure.
