Flow cell module
DEPOLOX Pool E The flow cell module DEPOLOX Pool E is a special flow cell adapter for sample water from various pool applications.
The flow cell module DEPOLOX Pool E is available as a non-
pressurized or pressurized version.
The non-pressurized and pressurized version of the flow cell
module differ in the number of sensors 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 sample water can be returned to
the system circuit.
All sensors that are required for the measurement tasks in
swimming pools, are attached orscrewed into the cover of the cell
body of the flow cell module DEPOLOX Pool E.
The maintenance-free flow control valve is the main hydraulic part
of the flow cell module DEPOLOX Pool E. The task of the flow
control valve is to keep 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 chlorine sensor
prevents the effective natural contamination of the electrode
surfaces and guarantees long-term chlorine measurements.
The transformation of the analog sensor signal for the digital
transfer to the electronic module 700 P is realized via the
electronic box DFMe. If optional sensors are used, this occurs via
the module SiDiSens LF (conductivity).

3.4 Function
3.4.1 General
The sample water is connected on the input side via the G1/2”
connection to the ball valve. The input pressure must be around
0.25 to 4.0 bar. To guarantee a constant flow, the minimum input
pressure must not be less than 0.25 bar.
In the flow direction, the connected filter unit gives the option to
install a stainless steel fine filter with a mesh size w=500 µm. The
fine filter is only used in conjunction with membrane sensors.
The return ball valve housing that is connected after the filter unit,
offers a kickback function and guides the ball for monitoring the
flow rate.
The multi-sensor combines the function of temperature
measurement of the sample water with a Pt1000, flow rate
monitoring following the float principle with reed switch and wide
area sample water earthing with stainless steel sensor housing.
A flow of the sample water that is not dependent on the operating
pressure is assured by the flow control valve. The correct sample
water flow of 33 l/h is preset at the factory, checked and logged.
The flow control valve is maintenance-free. 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.
The clear cell body holds thesensors and due to its design, is able
to provide good cleaning and service options. The sensors are
installed in the cover of the cell body with standardized threaded
connections or in special sensor holders.
The flow distributor cap screwed into the cell body from the bottom
enablesthecontinuoushydromechanicalcleaning oftheelectrode
of the chlorine sensor using special cleaning sand and thereby
effectively prevents the natural contamination of the electrode
surfaces. Clean electrode surfaces and a constant flow of sample
water are decisive criteria for a qualitative good chlorine
measurement and quick responsiveness.
The sample water runs across the top cell body outlet and directly
via a discharge nozzle for hoses with ID 6 mm or, in the case of the
pressurizedversion,via a ballvalve with G1/2” thread connection.
Withthe pressurizedversion, a maximumback pressureof1.5 bar
is permitted here.
For calibration purposes, there is also a specimen extraction
device. It is used to extract sample water from the low-pressure
side of the flow control valve in the cell body or to drain the cell
body for servicing purposes.

Flow cell module DEPOLOX Pool E Description

Two calibration holding clips are attached in the cover of the flow
cell module. The calibration holding clips are pushed through the
side of the basic housing of the flow cell module, thereby enabling
the “hand-free” calibration of the sensors with a buffer solution
from bags or in the calibration beaker.
The electronic box DFMe is used to convert the analog sensor
signals for the digital transfer to the electronic module 700 P. The
electronic box DFMe is integrated directly in the basic housing.
The sensors and sensor cables are built in and preconfigured in
the DFMe housing and are splash-proof in accordance with IP66.
If optional sensors are used, this occurs via the module SiDiSens
LF (conductivity). This measurement module is also built into the
plastic housing of the flow cell module.
An LED glow stick is screwed into the cover of the cell body as an
optical warning indicator.
Please note
When disinfecting the inline electrolysis systems, the chlorine
sensor and Redox single-rod measuring chain must be used, gold
version (gold electrode).
For applications in brine water with conductivity levels of 2.5 to
60 mS/cm(approx.4% NaCl),thetotal chlorinemembranesensor
TC2-S must be used.

3.4.2 Electronic box DFMe
The electronic box DFMe consists of a spray-proof housing with
built-in sensor electronics.
The base plate of the electronic box DFMe includes the sensor
input for the chlorine sensor and the evaluation electronics for the
multi-sensor for the temperature measurement and flow rate
monitoring.
Two additional slots are integrated on the base plate for the pH
and Redox single-rod measuring chain.
Via the integrated CAN connection socket, the electronic box is
connected to the electronic module 700 P using the CAN
connection cable.
If additional sensors, such as total chlorine and/or conductivity are
installed, the electronic box DFMe is equipped with a second CAN
connection socket. Sensors can be retrofitted at any time (see
„retrofit kits” on page 55).
