WFDNFT Waterflow Detector
The Safe Signal WFDNFT Waterflow Detector is designed for primary signaling in systems utilizing CPVC fittings. It features a rugged, NEMA 4-rated enclosure that is more damage-resistant than traditional metal designs, making it ideal for both indoor and outdoor use. The detector operates across a wide temperature range from 32°F to 150°F and provides reliable detection with high repeatability and resistance to vibration.
