Courtesy: System SensorThe WFDN Series Waterflow Detector by System Sensor features a timer dial, cover, and terminal block. The detector’s built-in time delay mechanism is immune to dust and other contaminants and designed for improved timer accuracy and repeatability. The directional cover is molded to be installed in one orientation, allowing the building owner or installer to see the direction of waterflow at a glance. The non-metallic material is UV- and damage-resistant, and it has a NEMA 4 enclosure rating. The wire-ready terminal block is designed for intuitive wiring. The paddle assembly allows the detector to perform in applications where an in-rush of water causes a lot of vibration.
