3. Description
3.1 General
The DEPOLOX® 5 E flow cell (module type D01) is part of the Pool Man-
agement System DEPOLOX® 5 E 700 P and the measuring and control
unit DEPOLOX® 5 E 700 M.
The DEPOLOX® 5 E flow cell (module type D01) is a special flow cell
adapter for sample water. In combination with the 700 P electronics mod-
ule (module type E01) or 700 M electronics module (module type E01)
and the integrated sensors, the DEPOLOX® 5 E flow cell measures and
controls parameters free chlorine, pH value, redox voltage and tempera-
ture. To determine parameters total chlorine, combined chlorine and con-
ductivity, further sensors can e installed.

Description DEPOLOX® 5 E flow cell
3.
DEPOLOX® 5 E flow cell is available in both a non-pressurized and a
pressurized version. The two versions differ in the number of sensors that
can be installed and in the design of the sample water outlet. The pres-
surized version can be retrofitted with the total chlorine membrane sen-
sor TC3 CAN. Please note that the standard cell body cover must be
replaced by an optional cell body cover, part no. W3T417351. The non-
pressurized version is characterized by a free sample water outlet. With
the pressurized version, the sample water is returned into the system’s
circuit.
The for sensors required for the measurement tasks (optional) and the
LED glow stick are inserted or screwed into the mounting hole in the cell
body cover.
The maintenance-free flow control valve is the main hydraulic part of
DEPOLOX® 5 E flow cell. It has the task of keeping the sample water flow
constant, irrespective of fluctuations in operating pressures.
The multi-sensor monitors the correct flow and records the temperature
of the sample water. The metallic sensor housing guarantees good sam-
ple water earthing. The continuous hydromechanical cleaning of the
electrode of the three-electrode measuring cell effectively prevents natu-
ral contamination of the electrode surfaces and ensures long-term stable
chlorine measurement.
DFMe electronics module converts the analog sensor signals for digital
transmission to 700 P electronics module or 700 M electronics module. If
a membrane sensor for total chlorine TC3 CAN (optional) is used, this is
connected directly to DFMe electronics module or routed through the
CAN connection on conductivity module SiDiSens (optional) to DFMe
electronics module. The conductivity sensor (optional) is connected to
DFMe electronics module through conductivity module SiDiSens.

3.3.2 DEPOLOX® 5 E flow cell
The function description of DEPOLOX® 5 E flow cell is described below
from the sample water inlet to the sample water outlet.
The sample water is connected on the input side to the shut-off ball valve
(A) via the G1/2” connection. The input pressure must be around 0.25 to
3.0 bar. To guarantee a constant flow, the minimum input pressure must
not be less than 0.25 bar. Otherwise, an optional booster pump must be
used. If the admission pressure exceeds 3.0 bar, an optional pressure
reducing valve must be used.
The sample water flows in the flow direction to the check valve housing
(C) through the filter unit (B) or through the built-in fine filter (membrane
sensors only). In the filter unit a stainless steel fine filter (sample water
fine filter) with a mesh size w=500 µm can be installed. The fine filter is
only used in conjunction with the membrane sensors.
The check valve housing (C) provides a kick-back function and guides
the ball for monitoring the flow rate.
The multi-sensor (D) monitors the correct flow by the float principle with
reed switch and measures the temperature with the Pt1000. The large-
surface transducer grounding is through the stainless steel sensor hous-
ing.
The flow control valve (E) ensures a flow of the sample water that is not
dependent on the operating pressure. The correct sample water flow of
33 l/h is factory-preset, checked and logged. If the admission pressure
rises, the valve ball moves towards the closing direction; if the admission
pressure drops, the ball moves towards the opening direction.
In the cell body (G) the 3-electrode measuring cell (H) with external
potentiostatic control circuit and refillable electrolyte tank is fitted. Work-
ing and counter electrodes are designed as half-ring electrodes and con-
sist of a special platinum alloy. The reference electrode is a silver–silver
chloride electrode, which is connected to the sample water via two mem-
branes. The reference electrode immerses in an electrolyte solution and
can also be refilled during operation.
The sample water that flows tangentially into the 3-electrode measuring
cell (H) ensures continuous hydromechanical cleaning of the sensor
electrodes with special cleaning sand, thereby preventing natural soiling
of the electrode surfaces. Clean electrode surfaces and a constant flow
of sample water are decisive criteria for a qualitative good oxidizing agent
measurement and quick response.
The 3-electrode measuring cell (H) is connected to 700 P electronics
module or 700 M electronics module through DFMe electronics
module (I) (DES sensor module for 3-electrode measuring cell). The
adjustable cell voltage Upot is output through the potentiostatic control
circuit. A measuring cell current (µA signal) that is proportional to the dis-
infectant concentration in the sample water is evaluated with the 700 P
electronics module or 700 M electronics module.

The cell body (G), which can be lit, holds the sensors and is designed to
allow convenient cleaning and servicing. These additional sensors are
installed in the mounting hole of the cell body cover (F) with standard
thread connections or in special sensor mounts.
The LED glow stick is fitted in the cell body cover for visual inspection of
the sensors, sand cleaning and for color indication of messages or faults.
The sample water runs off directly through the top cell body outlet (J)
through an outlet nozzle for hoses with inner diameter 6 mm. In the case
of the pressurized version, the sample water runs off through a shut-off
ball valve with G 1/2” A-connection. With the pressurized version, a max-
imum back pressure of 1.5 bar is permitted here.
For calibration, a sample taking unit (K) is fitted. It is used to draw sample
from the cell body through the low-pressure side of the flow control valve
and to drain the cell body for servicing.
Two calibration holding clips are attached in the cover of the DEPOLOX®
5 E flow cell. For hands-free calibration of the sensors with buffer solution
and calibration solution (bag or cup) the two calibration mounting brack-
ets are inserted on the side at the back of the main housing.
3.3.3 DFMe electronics module
DFMe electronics module consists of a spray-water tight housing with
built-in sensor electronics and is integrated in the main housing of the
DEPOLOX® 5 E flow cell. The sensor cables are prefabricated and are
splash-proof to IP66. The motherboard holds the sensor input for the 3-
electrode measuring cell, the LED glow stick and the evaluation electron-
ics for the multi-sensor. Optionally, the motherboard contains two addi-
tional slots for the pH and redox combined measuring and reference
electrode. To the integrated CAN socket the CAN connection cable to
700 P electronics module or 700 M electronics module is connected. Fur-
ther optional sensors, such as for total chlorine and/or conductivity mod-
ule SiDiSens can be connected through a second CAN connection
socket (optional).
