Aqualog Master


AQUALOG Master is the most complete RTU realized by FAST and it is dedicated to the management of water systems with crucial importance such as pumping stations, water treatment, pressures regulation, levels and flows adjustment.

Its advanced features make it essential to manage the water network smartly, by implementing solutions that help to save water and to reduce operating costs.

  • Real Time pressure adjustment on the basis of values at critical point (RTCP System)
  • “Discovery” Mode for detection and description of “Water Hammer” events thanks to high frequency virtual logger
