for measuring range depending metering of CIO₂:

• Simple constructed measuring system
• Compact flow-through housing for sensors
• Integrated control for measuring water flow rate
• Integrated flow rate adjustment
• Integrated sample valve for check measuring
• Flow-through housing is easy to clean
• One measuring transformer for Chlorine Dioxide and Redox, optionally expansible for pH
• Background illuminated display for best indication
• mA-outputs for signal transfer
• Remote control through customers external enabling contact is possible
• Possibility of limit control for all three measuring ranges

The Chlorine Dioxide and Redox measuring system is completely pre-assembled and cabled. This measuring system is used for measuring range depending metering of Chlorine Dioxide, e.g. in cold/warm water zones of bottle washers.

Depending on the differences of the rated/actual values a diaphragm valve is activated and Chlorine Dioxide is metered.

An insensible Redox measuring system is used for the independent control measuring. If the Redox value oversteps a free-adjustable maximum limit, the Chlorine Dioxide measuring switches off and the metering interrupts until the adjusted limit value is felt short of again.

Here, the indication of the pH-value can be very useful, because Chlorine Dioxide is reactive up to a pH-value of approx. 10,5.

In case of pH-values > 10,5 Chlorine Dioxide is reduced and it is not longer possible to give a clear statement about reactive Chlorine Dioxide. Therefore, in progress of the quality control, the pH-value should be measured and documented.
