ABSTRACT:
An application for a flow control system includes a movable plunger held within a stationary riser, the stationary riser being in fluid communication with a drainage system. The movable plunger is buoyant, assisted by one or more attached floats such that, when the liquid level around the flow control system increases to a pre-determined level, the movable plunger lifts due to the buoyancy, thereby maintaining the pre-determined distance between the surface level and a bottom surface of the movable plunger, keeping the flow rate at an approximately constant level independent of the water level.
