3. Description DEPOLOX® 5 E flow cell

3. Description

The DEPOLOX® 5 E flow cell (module type D01)

is part of the Pool Management System DEPO-

LOX® 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

module (module type E01) or 700 M electro-

nics module (module type E01) and the integ-

rated sensors, the DEPOLOX® 5 E flow cell

measures and controls parameters free chlo-

rine, pH value, redox voltage and temperature.

To determine parameters total chlorine, com-

bined chlorine and conductivity, further sen-

sors can e installed.

DEPOLOX® 5 E flow cell is available in both a

non-pressurized and a pressurized version.

The two versions differ in the number of sen-

sors that can be installed and in the design of

the sample water outlet. The non-pressurized

version is characterized by a free sample water

outlet. With the pressurized version, the sam-

ple 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 sample water earthing. The continuous

hydromechanical cleaning of the electrode of

the three-electrode measuring cell effectively

prevents natural contamination of the elec-

trode 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 chlo-

rine TC3 CAN (optional) is used, this is connec-

ted directly to DFMe electronics module or

routed through the CAN connection on con-

ductivity module SiDiSens (optional) to DFMe

electronics module. The conductivity sensor

(optional) is connected to DFMe electronics

module through conductivity module SiDi-

Sens.

DEPOLOX® 5 E flow cell 3. Description

3.5.2 Function

The sample water is connected on the input

side to the shut-off ball valve via the G1/2”

connection. The input pressure must be

around 0.25 to 3.0 bar. To guarantee a cons-

tant flow, the minimum input pressure must

not be less than 0.25 bar. Otherwise, an opti-

onal booster pump must be used. If the admis-

sion pressure exceeds 3.0 bar, an optional

pressure reducing valve must be used.

The sample water flows over the optional

strainer, which prevents dirt particles pene-

trating into the flow cell.

The sample water flows in the flow direction

to the check valve housing through the filter

unit or through the built-in fine filter (memb-

rane 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 provides a kick-back

function and guides the ball for monitoring

the flow rate.

The multi-sensor monitors the correct flow by

the float principle with reed switch and mea-

sures the temperature with the Pt1000. The

large-surface transducer grounding is through

the stainless steel sensor housing.

The flow control valve 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 direc-

tion; if the admission pressure drops, the ball

moves towards the opening direction.

In the cell body the 3-electrode measuring cell

(H) with external potentiostatic control circuit

and refillable electrolyte tank is fitted. Wor-

king and counter electrodes are designed as

half-ring electrodes and consist of a special

platinum alloy. The reference electrode is a sil-

ver–silver chloride electrode, which is connec-

ted to the sample water via two membranes.

The reference electrode immerses in an elec-

trolyte solution and can also be refilled during

operation.

The sample water that flows tangentially into

the 3-electrode measuring cell ensures conti-

nuous hydromechanical cleaning of the sensor

electrodes with special cleaning sand, thereby

preventing natural soiling of the electrode sur-

faces. Clean electrode surfaces and a constant

flow of sample water are decisive criteria for a

qualitative good oxidizing agent measure-

ment and quick response.

The 3-electrode measuring cell is connected

to 700 P electronics module or 700 M electro-

nics module through DFMe electronics

module (DES sensor module for 3-electrode

measuring cell). The adjustable cell voltage

Upot is output through the potentiostatic con-

trol circuit. A measuring cell current (µA sig-

nal) that is proportional to the disinfectant

concentration in the sample water is evalua-

ted with the 700 P electronics module or

700 M electronics module.

The cell body, which can be lit, holds the sen-

sors and is designed to allow convenient clea-

ning and servicing. These additional sensors

are installed in the mounting hole of the cell

body cover 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 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 pressuri-

zed version, a maximum back pressure of 1.5

bar is permitted here.

For calibration, a sample taking unit is fitted. It

is used to draw sample from the cell body

through the low-pressure side of the flow con-

trol valve and to drain the cell body for servi-

cing.

Two calibration holding clips are attached in

the cover of the DEPOLOX® 5 E flow cell. For

hands-free calibration of the sensors with buf-

fer solution and calibration solution (bag or

cup) the two calibration mounting brackets

are inserted on the side at the back of the

main housing.

3. Description DEPOLOX® 5 E flow cell

3.5.3 DFMe electronics module

DFMe electronics module consists of a spray-

water tight housing with built-in sensor elec-

tronics and is integrated in the main housing

of the flow cell. The sensor cables are prefabri-

cated 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 electronics for the multi-

sensor. Optionally, the motherboard contains

two additional slots for the pH and redox com-

bined 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. Further opti-

onal sensors, such as for total chlorine and/or

conductivity module SiDiSens can be connec-

ted through a second CAN connection socket

(optional). See design chapter 4.15 - Fig. 13.

3.5.4 Module SiDiSens LF (optional)

To measure the conductivity, conductivity

module SiDiSens LF (optional) is installed in

DEPOLOX® 5 E flow cell. The SiDiSens LF

module contains the sensor electronics for

conductivity sensor LF325 (4-conductor mea-

surement). Through the CAN interface the

SiDiSens LF module is connected with 700 P

electronics module or 700 M electronics

module. In addition, the optional membrane

sensor for total chlorine TC3 CAN can be con-

nected via the CAN socket. See design chapter

4.21.1 - Fig. 19.

4.2 Transport and storage

Transport

The flow cell is supplied in standard packaging.

During transport, the packaged system must

be handled carefully and should not be expo-

sed to wet weather or moisture.

Check that the transport packaging is unda-

maged. In the event of damage, please inform

the transport company immediately, as your

rights to compensation will otherwise be lost.

If a component is damaged, please contact

your affiliate immediately.

Keep the packaging until the flow cell has been

correctly installed and taken into operation.

Storage

Store the electronics module, the flow cell and

the sensors in a dry condition without any resi-

dual water in a dry place that is not exposed to

the weather. .

Shut-down

The flow cell may only be taken out of opera-

tion by trained and authorized personnel.

NOTICE

The DEPOLOX® 5 E flow cell is factory-confi-

gured according to the customer’s specific

requirements with the 700 P electronics

module according to the variant code (chap-

ter 3.1.1).

NOTICE

The scope of supply mainly differs in the ver-

sions of the DEPOLOX® 5 E flow cell (non-

pressurized or pressurized) as well as the

sensors.

ATTENTION

Damage to device and sensor!

Observe different storage temperatures

(chapter 3.7) and manufacturer specifica-

tions of the buffer solution and calibration

solution.

DEPOLOX® 5 E flow cell 4. Installation

4.3 Ambient conditions

4.3.1 Installation site

The following points must be taken into

account when installing flow cell:

• The flow cell must be protected from

moisture, rain, frost, heat and direct sun-

light and must not be installed outdoors.

• Do not use the flow cell in environments

where there are flammable gases, fumes

or dust or conductive dust.

• Do not subject the flow cell to strong

shocks or vibrations.

• The air in the room should be non-con-

densing.

4.3.2 Installation location for drinking

water, industrial water and waste

water

For problem-free mixing of the chlorine solu-

tion, the distance between chlorine addition

and sample water take-off must be at least ten

times the pipe diameter:

Example:

Pipe DN300

=> 300 mm × 10 = 3000 mm

=> minimum distance = 3 m

The time between chlorine addition and

excess chlorine measurement is the soak time.

It consists of the travel time between chlorine

addition point and sample water take-off and

the travel time between sample water take-off

and measurement (sample water line to flow

cell). Keep the sample water line to the flow

cell as short as possible.

For longer required soak times, for example 5

to 15 minutes, a delay tank can be installed

into the sample water line immediately before

the flow cell. Note that the longer soak time

prevents chlorine addition control based

purely on excess chlorine. Instead, combined

flow and excess chlorine dependent control

must be used. This also applies to the use of

chlorine, chlorine dioxide and ozone as disin-

fectant.

4.3.3 Installation site for pool water

The sample water take-off point must be

installed in the pool return line according to

standards (see DIN 19643, DIN = German

Industrial Norm). Make sure that the sample

water take-off point is upstream of the floccu-

lant station.

4.4 Mechanical installation
