Invented by Peter Langemann, the Langemann Gate was developed through a cooperative effort between St. Mary River Irrigation District, Peter Langemann and Aqua Systems 2000 Inc. (AS2I). The Langemann gate, used in conjunction with one of AS2I’s controllers, provides solutions to a host water of control problems. The patented design has gained recognition due to its simplicity, overshot technology and low power requirements.
A Langemann Gate with controller can either:
- Maintain a constant upstream water level (such as in check structure) or
- Provide a pre-determined constant flow to downstream users (such as a turnout)
- Irrigation check structures
- Turnout structures
- Spillway structures
- Diversions structures
- Water and sewage treatment plants
- Flood control structures
- Superior trash management
- Low power requirements: The unique distribution of water pressure afforded by the gate configuration and the low friction operating components provide for remarkably low power requirements.
- Precise Positioning: The Langemann Gate provides positive linear movement in either direction. Convenient staff gauge placement and the linear relationship of the gate and water level provides reliable operating information.
- Ease of Installation: All but the very large gates are fully assembled for shipping. A small crew and a suitably sized crane can install a gate in a couple of hours.
