Site/System Demonstration Video
This video displays how the site and screw function as the water course flow increases from 0 cms to 28.28 cms. It demonstrates how the screw remains shut off until the water hands off flow plus required start up flow the screw is reached. Once the screw starts up the hands off flow to the fish ladder and hands off flow over the weir are maintained. As flow increases from here screw RPM increases to accept the greater flow while maintaining the hands off flow over the weir and to the fish ladder. Once the screw reaches its’ maximum flow capacity the water level over the weir starts to increase thereby increasing the effective hands off flow.
