Version 16.0.40539 Release Notes

Key Highlights

  • Incorporated PIPE-FLO® Overtime 2009 functionality into PIPE-FLO® Professional enabling the user to simulate their system over a period of time.*
  • Added the ability to define Tank Geometries to the Tank devices.
  • Centrifugal Pump Speed can now be adjusted between Lineups.
  • Updated the PIPE-FLO® Professional user interface with more modern icon images.

*PIPE-FLO® Overtime module is purchased separately and operates on PIPE-FLO® Professional v16.0 (and above) exclusively
