Waterflow detectors are available in a variety of configurations and accommodate 2 in through 8 in pipe for commercial riser applications, as well as 1 in NPT and CPVC connections for residential or branch line signaling. The WFDN series detectors provide a mechanical time delay to help prevent false alarms due to water pressure surges or air trapped in the system. The time delay mechanism now includes an easy-to-rotate timer dial with high contrast pad printed markings to make setting the device easy. The terminal block is designed for easy wiring and the device cover is designed to be damage and shock resistant.
