D01-915en201911 Manual eCHEM Chlorine Dioxide
Chlorine Dioxide //
Use
A sudden failure of the sensor can lead to dangerous over-metering. Take appropriate precautions in
this case! Check system for odour, check water for abnormal discolouration. In case of strong over-
metering, the DPD-1 measurement can remain colourless because the dye is bleached by the chlorine
present.
4.1 Installation with retaining ring in the flow cell
For installation in a flow cell, you need the sensor for chlorine dioxide measurement on the one hand and the flow cell on the
other.
1. To install the sensor in the flow cell, you must first remove the screw connections on the flow cell FLC.
2. Push the slide ring from the FLC under the retaining ring of the sensor.
3. Push the 25x2.5 O-ring (silicone) underneath the slidw ring over the sensor (see figure).
Make sure that the sensor is prepared as described in chapter 3.
Make sure that the 30x2.6 O-ring (Viton) is still in the flow cell at the insertion edge.
4. Now slowly insert the prepared sensor into the flow cell as shown in the figure.
5. Carefully slide the screw connection over the sensor and screw it tight, otherwise leaks may occur!
6. Open the sample water drain.
7. Slowly open the sample water inlet.
Avoid installations where air bubbles can form in the sample water.
