The AquaMetrix 2250 Series Flow Controller is designed to be the most flexible, easy to use, and easy to see multi-parameter controller on the market. The 2250 Series allows you to choose Conductivity, pH, ORP or Flow. The user interface was designed under the principle that the user should not need to read the manual.

The 2250 provides control of external devices using its three independent control relays. The third relay is provided to act as an alarm relay or a third process control relay. Each relay has both adjustable high and low on set-points and can be set for either a rising or falling process. Each relay has its own cycle timer, with adjustable on and off times. This feature enables tighter control of batch processes by eliminating chemical overshoot.

Applications for the 2250 Series include:

  • Industrial process control, e.g. plating, food and beverage, chemical processing, pulp & paper, mining, food and beverage
  • Municipal water and wastewater treatment
  • Industrial and Municipal Waste treatment and Neutralization
  • Fume scrubbers
  • HVAC, cooling towers and boilers
