FLOOD DETECTION CONTROL DEVICE FOR REDUCED PRESSURE BACKFLOW PREVENTERS
A flood control device for detecting discharge from a release outlet, comprising a receptacle having an upper opening, a bottom, and a drain hole; a first water level sensor configured to be triggered by water reaching a first level; a second water level sensor configured to be triggered by water reaching a second level, wherein the first water level sensor is closer to the bottom of the receptacle than the second water level sensor, wherein triggering the first water level sensor represents a low flow signal, and triggering both the first water level sensor and the second water level sensor represents a high flow signal. The low flow signal can be used to trigger a warning, and the high flow signal can be used to trigger automatic shutoff and/or shutoff alarm.
