WTW-2020 (IQ Sensor Net)

Improve operational efficiency with continuous data. With an easily scalable solution, the 2020 XT allows for the connection of up to 20 sensors. Add sensors at any time and at any location or change them out with ease. This completely modular plug-and-play system allows you to monitor and control the water quality in your wastewater facility continuously and accurately.

  • Online Dissolved Oxygen Analyser
  • Up to 20 Sensor Inputs from any 700 IQ Sensor
  • Digital modular multiparameter system
  • Decentralized system for 1 to 20 sensors with integrated terminal

The high-performance processor of the terminal/controller WTW 2020 coordinates all tasks inside the network. The USB interface allows quick data exchange via a USB stick or directly to external systems. The system status LED provides reliable and quick information about the function and the system status.

The system stores the measured values of a new connected sensor and all configuration data automatically. The large, coloured display and the large buttons ensure a clear and customer-friendly operation at any conditions.

When integrating two MIQ/TC 2020 3G into the system, the system security and therefore the availability of the total system is ensured by the controller-redundancy-function. This lets you use one MIQ/TC 2020 3G as a terminal and a controller (fixed installation), and the second one as a mobile terminal. By including this into the network, you can have remote communication as well as remote maintenance.

For the remote maintenance from a PC, you need to install the software IQ Software Pack CONNECT. This setting can be made via a user interface according to the MIQ/TC 2020 3G terminal. In addition, you have the option to transfer measuring and configuration data of the system to a computer. For the control of the IQ Web Connect the MIQ/MC3 is required.
