Field of application

The following list is a general representation of basically suitable applications for this product. Please contact your personal representative to discuss the use of the product in your individual application.

  • 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.
