Measuring and Control
A big technological step forward
Measuring and control
The most important message of the training
• Grundfos completely changes its measurement and control range ( former
DIS, DIA range).
• We can measure and control in the future :
• -pH
• -redox potencial
• -free chlorine
• -total chlorine
• -chlorine-dioxide ( ClO2 )
• -conductivity
• -hydrogen-peroxide ( H2O2)
• -peracetic-acid ( CH3COOOH )
We are entering into the 21st century of M&C

Digital Sensors
- Probes can be operated according to the “plug & measure” principle. With a
simple plug connection, which provides power supply and data
communication, the probes are connected to a terminal and are ready for use.
- All probes are pre-calibrated exworks and do not require any conditioning before they
can be used
- All probes can be used continuously (OnLine) and directly in the water (InSitu).
-The “plug & measure” principle avoids complex installation procedures on site and does
not only save time during initial operation, but also reduces avoidable errors.
-The highly optimised design completely eliminates all moving
parts in contact with the water. This reduces failures and maintenance
dramatically.
-Using standardised mounting devices physical probes can be installed quickly and
effortlessly, either submersed (InSitu) or in a flow through setup (by-pass, monitoring
station).
-Like all other s::can instruments s::can physical probes are intelligent
instruments - amongst others local calibrations are stored on
the probes and auto-diagnosis procedures are used to ensure best
pH and redox mesurement
The pH::lyser / redo::lyser
pH and redox mesurement
pH::lyser
is a multi-parameter probe that measures the pH value and temperature
directly in the water. The pH::lyser uses the temperature
to correct the result of the pH measurement online. The non-porous,
solid-state reference electrode ensures excellent pH readings
and a long lifetime of the electrode.
redo::lyser
is a probe that measures the oxidation-reduction potential (also
known as redox potential) and temperature directly in the water.
The non-porous, solid state reference electrode ensures excellent
ORP readings and a long lifetime of the electrode.
Measuring and control
A big technological step forward ( pH measurement
To remember
what is pH.
-log 10 [ H+]= pH
)
Measuring and control
A big technological step forward ( pH measurement )
When we measure pH we really measure mV and mV is converted to pH.
Measuring and control
A big technological step forward ( how pH electrode works)
The whole pH measuring circuit consists of a measuring electrode ( pH
electrode ) and a reference electrode. Both electrode are immersed in the
same solution. In order to obtain a definit pH value the reference electrode
must have a defined stable potential which is independent of the measured
solution.
Combination electrode
In the combination
electrode, glass ( pH)
electrode is
concentrically
surrounded by the
reference electrolyte
Electrical connection

• Maintenance and Service
• Manual cleaning is unnecessary because of non-fouling special reference
electrode. Automatic cleaning device is available for extreme application
• Check of accuracy/calibration-for complience monitoring and reporting
monthly
• for other application: Monthly to quarterly
• Exchange of combination electrode to refurbished one every 12 ( 12-36)
months- prior failure

Conductivity measurement
The condu::lyser
Measuring and control
Conductivity measurement
The electrical conductivity of a solution of an
electrolyte is measured by determining the
resistance of the solution between two flat or
cylindrical electrodes separated by a fixed
distance.
Electrolyte
We measure its conductivity
High quality deionized water has a conductivity
of about 5.5 μS/m ( 0,055 mS/cm), typical
drinking water in the range of 5-50 mS/m (50500 mS/cm), while sea water about 5 S/m ( 50
mS/cm) (i.e., sea water's conductivity is one
million times higher than that of deionized
water).
Measuring and control
A big technological step forward
Conductivity measurement
How does it work ?
4 electrodes measurement
-consists of 2 voltage and 2 current electrodes
-AC applied to current electrodes
-voltage drops depending on EC of medium on
voltage electrodes
-current increases with an increase in voltage
drop across electrodes
-due to regulation of measurement voltage on
current electrodes coating on conductivity
electrodes is compensated.

The Chlori::Lyser
Free Chlorine
Total Chlorine
chlori::lyser
• chlori::lyser monitors free or total chlorine - mounted in a flow
cell setup. Due to the membrane covered amperometric measuring
principle, flow and pH fluctuations of the water do not influence
the measurement result.
• Additionally, the integrated temperature compensation and the special,
third electrode completely eliminates potential interferences.
• Their unrivalled measurement features in combination with the lowest
possible total costs - initial cost and foreseeable operational costs make
s::can sensors the most attractive solution available today.

Intelligent
All s::can sensors are intelligent, they are digital and have the
controller, the brain, built in. They check their health every
second and can communicate with the operator.
Optical
If possible, we always use optical methods, since they are just
better, more reliable, simpler and more accurate. If no optical
method is suitable, we choose the next best alternative.
Online
We make nothing for laboratories, nothing that consumes
reagents, nothing with moving parts. s::can is the only real
„on-line“ company in the industry that offer an almost
complete range of sensors and parameters, and nothing else.

response time: 90 % in 1 minute
sensor drift less than 1 % per year
most cost efficient sensor; system costs as part of a s::can
system and costs of ownership are unmatched

Types
The ammo::lyser
Maintenance and Service
Manual cleaning unnecessary because of efficient
pressure air automatic cleaning
Check of accuracy / calibration
for compliance monitoring: monthly
other applications: monthly
Exchange of NH4 electrode to refurbished one every
12 (6 – 24) months – prior to failure
Overnight conditioning of new electrode in the medium,
before calibration = matrix adaptation
Exchange of reference electrode to new one every 12
(12 – 36) months – prior to failure
Shelf-life of refurbished electrode 1 year
fluor::lyser
The flour::lyser
What is unique ?
s::can plug & measure
measuring principle: ISE (ionenselektive elektrodes)
no cross sensitivities in typical drinking water applications
multiparameter probe
long term stable, factory precalibrated
automatic cleaning with compressed air
easy and quick mounting and measurement directly in the media (InSitu) or in a flow cell
(monitoring station)
operation via s::can terminals & s::can software
ideal for drinking water
minimal maintenance
plug connection or fixed cable
fluor::lyser
What do we measure?
flour::lyser measures fluoride and temperature
