ProMinent : The NEW Dulcometer® Disinfection Controller/Monitor

16 measurement locations with just one central unit – with ProMinent®
The NEW Dulcometer® Disinfection Controller/Monitor
The Dulcometer® Disinfection Controller/Monitor and DULCO®-net technology are revolutionizing measuring, control and metering technology in public water systems. The decentralized modular concept with one single central unit controls sensors and actuators for up to 16 measurement locations.

Simple to plan
The CANopen bus system known for vehicle technology only needs one single bus line. The central unit can be installed in an easily accessible location, e.g. in the operator’s room. It is the DULCO®-Net which offers a cost-effective solution: Up-to 16 systems can be displayed through the central unit!

Simple to install
Installation and commissioning are quick and easy – one single bus line is sufficient. Coded socket connections prevent incorrect connections and polarity problems. Remote access with any PC and standard Internet Browser is possible.

Simple to operate
The 1/4 VGA colour display presents clear text dialogues to the user. A built-in on-line help is displayed with the push of a button. The measurement data can be displayed with the integrated videographic recorder and transferred to a PC using the Dulcometer® Disinfection Controller/Monitor’s internal SD card.

Key Features and Benefits

for planners

  • Simply upgrade
    Thanks to the bus line, the decentralised modular system can be easily upgraded. Thanks to the CANopen bus, the Dulcometer® Disinfection Controller is prepared for the future.
  • Simply central
    An easily accessible central unit displays all sensors and actuators. Dulcometer® Disinfection Controller is the ideal solution for one filtration cycle. DULCO®-Net technology controls up to 16 locations.
  • Simply cost-effective
    Dulcometer® Disinfection Controller with DULCO®-Net offers a truly cost-effective solution: An intelligent controller for several locations with guaranteed simple installation. The economic solution

for fitters

  • Easy with just two lines
    It only needs a magenta-colored bus line for networking and a main cable – and the Dulcometer® Disinfection Controller is completely wired and ready for commissioning.
  • Easy to connect
    Coded socket connectors ensure that no polarity problems arise because of accidentally switched terminals. If you know how to use a screwdriver you will be able to install the Dulcometer® Disinfection Controller.
  • Easy to wire up
    The star-type cable configuration is a thing of the past. Today, one single bus line links all sensors, actuators, and the central unit.

for operators

  • Easy to understand
    The illuminated display has the size of a 1/4 VGA colour screen (approx. postcard size). And all data are displayed in full text in the appropriate language. Cryptic abbreviations are history.
  • Easy to get help
    And should any queries arise: A context-sensitive online help appears on the display with only one push of a button.
  • Easy to use
    All data can be displayed on the control unit display and via PC and Internet browser. A multimedia card slot is provided for wireless data transfer.
