SprinkFDT Fluid Delivery Time Calculator

As the only UL listed software for calculating fluid delivery time, SprinkFDT calculates dry valve trip time and water delivery time to the remote area without the requirement of a physical trip test, saving time for the installer and approving authority.


  • Possibly reduce the number of dry systems required per code thus reducing the number of costly riser components
  • Ensure the project is code-compliant before the project begins
  • Quickly determine the need for an accelerator
  • Evaluate dry system performance on multiple factors impacting water delivery time
  • Real-time viewer of the sprinkler system filling; can illustrate the impact of system volume, shape, pressure, and temperature 
  • Share files electronically with the approving authorities with free SprinkCALC viewer
