The WFDN Series Waterflow Detector by System Sensor of St. Charles, Ill., is fully redesigned and features a new timer dial, cover, and terminal block to help save installation time, according to the company. The timer dial is a first for waterflow detectors with a built-in time delay, which is designed for improved timer accuracy and repeatability, according to the company.
The directional cover is molded so it can only be installed in one orientation, allowing the building owner or installer to see the direction of waterflow at a glance. The new nonmetallic material is UV- and damage-resistant, and it helps provide a better seal while maintaining a NEMA 4 enclosure rating.
The wire-ready terminal block is designed for intuitive wiring and places the common terminal on a different elevation, making it easy to determine how to properly wire the switch.
