A WFD Series Water flow Detector, also known as a flow switch, is an electro-mechanical device designed to send a signal to a local alarm or monitored panel and/or fire department when a continuous flow of water occurs through a fire sprinkler system’s piping. This flow signifies an activated sprinkler head or a leak in the system.
