Description

The F27 time delay flow switches are paddle flow switches with built-in digital timers that override the off state
of the flow switch and allow a pump to start in spite of an initial lack of flow. They also have adjustable run-on
timers that let the pump ignore minor flow interruptions while still being fully protected against running dry.

Application
Where a timed ignore response is required

  • Loss of flow protection for pumps
  • Control of flow in ultra pure water systems
  • Flow status signalling in water treatment plants
  • Control of effluent and fluid neutralising systems
  • Corrosive and saline ground water applications
  • Applications involving sea water or brine solutions
  • Safety and control signalling for chemical handling
  • Control and protection of chemical pumps
  • Irrigation and turf watering systems control
  • Horticultural and hydroponics system control
