T-Tap Waterflow Detector

WFDTN t-tap water flow detectors consist of a rugged, NEMA 4 rated enclosure that is more damage resistant than previous metal designs. The waterflow detector is designed for both indoor and outdoor use, with the widest available temperature range, from 32 to 150 °F. Both the WFDTN with incorporated timer and WFDTNRN with immediate activation fit any tee that has a 1 inch NPT branch. Twelve different clearly marked plastic paddles are available to fit different installation configurations.

Features & Benefits:
  • New directional cover allows installers and inspectors to easily see the direction of flow
  • UL-listed models are NEMA 4 rated
  • New cover provides a better seal, is lighter weight, not painted and corrosion resistant
  • Less exposed metal reduces shock hazard, plastic cover acts as insulator and is resistant to arcing
  • Visual and audible switch activation (73 dBA)
  • Field-replaceable timer/switch assembly
  • Improved wiring with new terminal block layout, wire-ready terminals, accommodates up to 12 AWG wire
  • Switch synchronization activates both alarm panel and local bell or horn strobe
  • Tamper-resistant cover screws, snap-in optional cover tamper switch
  • Improved water sealing
