Field of application

The following list of applications are general examples of generally suitable applications for this product. Please contact your local sales representative to talk about the applicable use of this product in your specific case / environment.

  • Boiler blowdown monitoring

    Technical Details

    • Selectable chemical feed mode: Provides 3 feed modes; feed on volume, blowdown & feed, and percentage time.
    • Conductivity control: Can be programmed using timed or continuous sampling.
    • Water meter input: Allows for chemical to be fed based on water volume versus timed pump control methods generally found on comparably priced controllers.
    • What and Why Information: Diagnostics shown on display are a valuable troubleshooting tool. Conductivity valve and chemical pump relays show complete status. Shows WHY the relay is on/off.
    • Single point calibration: For ease of startup and operation. Warning message immediately detects fouled or faulty sensors.
    • Controller run time: Gives total hours per day and total operating days since initial installation.
    • Robust diagnostics: Provides complete 24-hour history of blowdown valve operation and chemical relay timing intervals.
    • Keypad password: Eliminates unauthorized adjustments.
    • Communication options: Includes Ethernet networking, dry contact alarm relay or 4-20 mA output on conductivity.
    • Optional web browser user interface with networking capability: Provides ability to direct connect to the controller from a portable workstation, such as a laptop computer. You can also view critical processes remotely using a LAN connection.
