Potable, industrial and swimming pool water are disinfected
almost exclusively by adding chlorine, chlorine dioxide, ozone or
potassium permanganate.
With the flow block assembly DEPOLOX
®
5 with integrated 3-
electrode cell, the contents of this disinfectant can be continuously
recorded.
A sensor module ("DES" for 3-electrode cells) and terminal strips
are used to connect the flow block assembly DEPOLOX
®
5 to the
SFC. Various controller functions are available depending on the
application selected. The flow block assembly DEPOLOX
®
5 is
also used for holding other sensors, such as pH, Redox, fluoride,
conductivity or membrane sensors for free chlorine, chlorine
dioxide, ozone, total chlorine, or combined chlorine.
A pressurized and non-pressurized version with flow rate control is
available as a flow block assembly with integrated 3-electrode
cells (see "Overall Function" page 31).
Mode of operation of the 3-
electrode sensor in the flow
block assembly DEPOLOX
®
5
The measuring cell in the flow block assembly DEPOLOX
®
5 is a
3-electrode cell with external potentiostatic control circuit. Working
and counter electrodes are designed as half-ring electrodes and
consist of a special platinum alloy.
The reference electrode is a silver/silver chloride electrode, which
is connected to the sample water via two diaphragms
(membranes). The reference electrode with PVC support is
immersed into an electrolyte solution.
The electrolyte supply can be replenished during operation if
necessary (see7.2 “Maintenance of flow block assembly
DEPOLOX® 5”).
By connecting the 3-electrode cell to the SFC (DES sensor module
for 3-electrode cell), a variable Upot cell voltage can be output
between the working electrode (red) and reference electrode
(white) via the potentiostatic control circuit. A measuring cell
current (µA signal), which is evaluated using the SFC, sets itself
proportional to the disinfectant concentration in the sample water.
A special cleaning sand is filled into the flow block assembly, which
is circulated by the sample water current and continuously cleans
the platinum electrodes.
A multi-sensor is integrated into the flow block assembly
DEPOLOX
®
5 to measure the temperature and monitor the flow
rate. This is made of a stainless steel housing and is used
simultaneously as the sample water grounding (for connection to
SFC, see 9. “Wiring Diagrams”).
