Obermeyer Spillway Gates are most simply described as a row of steel gate panels supported on their downstream side by inflatable air bladders. By controlling the pressure in the bladders, the pond elevation maintained by the gates can be infinitely adjusted within the system control range (full inflation to full deflation) and accurately maintained at user-selected set points.
Obermeyer spillway gates provide excellent controllability over a full range of flow rates, water elevations and gate positions. Individual gate segments operating on the same air supply line maintain a uniform crest height relative to each other. Obermeyer spillway gates also provide very repeatable positioning relative to inflation pressure.
Gate elevation is accurately controlled by PLC as headwater level
can be used to precisely measure and control flow.
