Memosens 2.0 - Simple, safe, connected

Memosens technology has revolutionized data transfer
security by digitalizing the measured value in the sensor
and transferring it to the transmitter without a contacting,hence moisture-sensitive, connection.
This jump in technology has eliminated general limitations
encountered to date.

Memosens 2.0 is leading Memosens technology into the
future. The upgraded sensor electronics offer:• Ideal foundation for IIoT connectivity: You always havethe relevant information on your measuring point close
to hand using the right app.
• Predictive maintenance 2.0: The storage capacity for up
to 8 times more relevant data provides an excellent basis
for predicting maintenance requirements and planningmaintenance cycles. This ensures more accurate process
management and enhanced plant management.
• Increased flexibility when configuring the measuring
point even in hazardous areas: Any Ex-approved
Memosens 2.0 sensor can be connected to any Exapproved Liquiline transmitter.

Memosens 2.0 collects networked data

Memosens 2.0 is easy to use

Maintenance strategies taken to a new level• The upgraded electronics unit means that the newsensors can store eight times more calibration data.
• More available data enables customers to develop a
specific maintenance strategy for their measuring points,
e.g. with Heartbeat Technology, thereby extending thesensor service life.
• By exchanging, cleaning and calibrating them regularly,
Memosens sensors can live up to 30% longer – even inharsh conditions.
• For further analysis and optimization of the measuring
points, Memosens 2.0 can be supplemented with theMemobase Plus software, which enables full tracking of
all sensors.

Very user-friendly• The bayonet lock of the plug-in head can be easily
opened and closed without twisting the cable.
• Real plug & play: Each Memosens sensor is automaticallyrecognized and identified by the transmitter.
• Sensor and process-specific data is stored directly in thesensor head. Personnel no longer need to worry whether
they have all they need for calibration when they are out
in the field– they simply take a precalibrated sensor andexchange it on-site.
• Calibration is performed in the comfort of the laboratory
where harsh weather conditions and difficult access tomeasuring points do not cause complications.
• Quick sensor replacement at the plant reduces the timerequired for maintenance and thus plant operating costs.

Liquid analysis places high demands not only on the sensor
element but also on the transmission of the measured value
from the sensor to the transmitter. When measuring pH,
low currents and very high sensor internal resistances also
require a high-impedance connection to the transmitter.
Moisture in the connection can change the measured value
and may even result in measurement failure.

Ideal basis for IIoT services• The sensors‘ digital data can be transferred directly to
the Netilion cloud and used for IIoT applications such as
Netilion Health or Value.
• Netilion Health allows our customers to query thesensor‘s health status from anywhere via smartphone,tablet or laptop and respond quickly to an unexpected
event.
• Netilion Value allows customers to access their measured
values at any time and from anywhere so they always
know exactly what is happening at the plant.
Digital access to this information means that they canaccuratey manage the quality of their operating processes – even remotely.

Benefits• Safe digital data transmission: inductive, corrosionfree, 100% reliable• Sensors store up to 8 times more calibration data forpredictive maintenance and IIoT services• Fast plug & play with pre-calibrated sensors• International de-facto standard

Memosens 2.0 guarantees reliability
Reliability you’ve come to expect• Memosens technology digitizes the measuring signal in
the sensor and sends it to the transmitter via an
inductive, non-contact connection. This makes themeasurements completely resistant to environmental
influences such as moisture, corrosion and salt bridges.
• The galvanic isolation of sensor and transmitter
eliminates interference signals.
• The digital measured value transmission automaticallyresults in an error message if the signal flow isinterrupted: this dramatically increases the reliability andavailability of the measuring point.

technology

Maximum flexibility even when setting up a measuring
point in hazardous areas• All transmitters, from a multiparameter andmultichannel Liquiline transmitter with cCSAus approvalto the Exapproved Liquiline CM42 transmitter or the compact
Liquiline Compact CM72/CM82 with Ex approval, can be
combined with the Memosens 2.0 sensor versions forhazardous areas.
• Be it a field device, panel mounting or compact
transmitter, compliance with the requirements forhazardous areas is always guaranteed and the measuring
point is compatible.
• The plant planning stage is easier and faster and plantsafety is increased.

pH sensors using the potentiometric method
The method of pH measurement using
glass electrodes is a potentiometricmeasurement method. Since glass isan electrical insulator, transmitters foranalog pH measurement must havean extremely high input impedance.
In the case of Memosens electrodes,
signals are transmitted digitally
without interference. The measuring
effect is based on a pH-sensitive glass
membrane whose surface reacts tothe acid content of the solution witha specific voltage. This voltage isthen measured relative to a reference
element made of silver/silver chloride(Ag/AgCI).

Benefits• Universal use (pH 0-14)• High chemical resistance• Lead-free shaft glass• Temperatures up to 140 °C

Nowadays, the most modern pH
glasses display high selectivity (lowcross-sensitivity to ions other thanH+) over a wide temperature range. A
pH sensor can perform linear measurement of a material component over
an impressive concentration range of
14 (!) exponents. pH glass electrodes
have become a standard worldwide.
Glass has the advantage of being very
chemically inert and very stable whenworking with hot acids and alkalis.
This means that pH glass electrodes
can be used universally in a multitudeof applications.
Combined pH/ORP sensors enable
simultaneous measurement of pH
value and ORP potential. These values
can be used to calculate the rH value
which is an indicator of the oxidizingor reducing effect of a medium.

ORP sensors using the potentiometric method
Even though only one sum parameteris measured, ORP measurement isan effective and low-cost method
which can be used for chromate
detoxification, cyanide detoxificationor to measure the metering ofoxidants for disinfection purposes.

The ORP value is an indicator of theoxidizing or reducing properties ofa process medium and is measured
in mV. In aqueous media, themeasuring range is between-1 500 mV and +1 500 mV. A
precious metal electrode (silver, goldor platinum) acts as the measuring
electrode. As is the case with pH
measurement, the electrochemical
potential is measured against asilver/silver chloride reference(Ag/AgCl) and indicated in mV.

The ORP value can also be
indicated as a percentage. Here,two characteristic mV values are
assigned to a 20 % and an 80 % value,
making it possible to detect activities
pertaining to chemical reactions
and also of reaction endpoints.

All ORP pairs in a process make up
the oxidation reduction potential. As
such, in contrast to pH measurement,
the ORP value is a sum parameterthat cannot be assigned quantitatively
to the individual ORP pairs.

Non-glass pH sensors using the ion-selective method
The pH value can also be measured
with an ion-selective field effecttransistor (ISFET). It is, in effect, a
simple transistor with a source anddrain that are separated from the basegate by a semiconductor. Hydrogenions from the medium may
accumulate here. The resulting
positive charge on the outside is"mirrored" on the inside of the basewhere a negative charge occurs. This
makes the semiconductor channel
conductive. The lower the pH value ofthe liquid, the more H+ ionsaccumulate on the base and the morecurrent can measurably flow between
the source and drain.
The accumulation of protons is apurely electrostatic effect. As a result,the sensor material does not change
and the need for recalibration is by nomeans as frequent as with glass
electrodes. Since there is no gel-likelayer, ISFET electrodes are also
suitable for pH measurement in media
with a low proportion of water.
Modern gate materials are highly
selective and follow the Nernst law inclose tolerance limits. The particularlyrobust nature of the sensors is a resultof the ISFET chip being embedded in astable and unbreakable PEEK body(polyetheretherketone; polymer
thermoplastic with excellent
mechanical and chemical resistanceproperties that are retained at hightemperatures). ISFET-based pH
electrodes are primarily used inapplications where unbreakability isrequired, as is the case in the food andlife sciences industries, since fragile
glass electrodes could cause problems
if broken.

Conductivity sensors using the conductive method
The electrical conductivity of liquids isdetermined using a measuring
arrangement incorporating twoelectrodes located opposite one
another - as in a capacitor.
The electrical resistance R, or its
reciprocal value - the conductancevalue G - is measured applying Ohm’slaw. From this, the specificconductivity (Greek; kappa) is
calculated using the cell constant k,which describes the geometry of theindividual electrode arrangement:
κ=k G=k/R
The cell constant k usually has theunit cm-1 and is specified by the
manufacturer for each sensor. Withan ideal plate capacitor, the cell
constant is:
k = electrode spacing / electrode surface

The choice of sensor with a specificcell constant depends on the desired
measuring range: the lower the
conductivity, the smaller the cell
constant selected. The size of the cell
constant determines the optimum
arrangement of the electrodes. For
example, for ultrapure water the
preference is for a concentricarrangement of cylindrical electrodes.
Four-electrode method
The four-electrode method is particularly suited to applications which covera wide measuring range. The sensor
has two additional electrodes tocompensate for polarization effects
that occur with two-electrode sensors
at higher conductivities. The two
additional electrodes measure thevoltage drop in the medium which
depends on the medium’s conductivity. The connected transmitter
calculates the conductance from themeasured voltage and the given
current.

Two electrodes are located opposite one
another – as in a capacitor

Two additional inner electrodes compensate
the polarization effect.

Conductivity sensors using the inductive method
In the case of inductive conductivity
measurement, a transmitter coilgenerates a magnetic alternating fieldthat induces an electrical voltage inthe medium. This sets the positively or
negatively charged ions in the liquid inmotion and an electrical alternating
current flows through the liquid.
This current produces a magnetic
alternating field in the receiver coil.
The induction current produced in thecoil in this way is evaluated by theelectronics system and used to
calculate the conductivity.

Experts in turbidity andsludge level measurement
Focus on water and wastewater
In the turbidity and sludge levelmeasurement field, the focus ison providing solutions for thewater and wastewater industries.
Whether you’re measuring turbidity
downstream of a waterworks sandfilter the optical metrology limit
range or the solid contents of sewage
sludge which is too concentrated to bepumped, Endress+Hauser’s sensors
cover a wide range of applications.
With the 90-degree scattered lightmeasurement system that complies
with DIN/ISO specifications, we
provide a universal sensor systemthat can be used for most common
applications. Our product portfolio iscomplemented by absorption sensors
that measure the transmitted lightand sensors based on the 4-beamalternating light method. Dependingon the particular measuring range,these use scattered light, forward
scattered light or backscattered light.
These optical sensors are also used insludge level measurement. Ultrasonics
provides an alternative method for
determining the level of sediment ina basin or container by measuring the“time-of-flight” of the acoustic signal.
Flexible installation
Turbidity sensors fromEndress+Hauser are suitable for
installation in pipes or containers
and for immersion applications inbasins or channels. A wide range of
assemblies safely positions the sensor
in the process, including the CYA112
immersion assembly, the CYA251,

Turbidity measurement

Turbidity sensors using established scattered light methods, 4-beamalternating light method and attenuation measurement
Scattered light methods
The 90-degree scattered light methodin accordance with ISO 7027 /EN 27027 measures turbidity values
under standardized, comparable
conditions mainly in the low turbidity
range. The 135-degree scattered
light method is optimized for themeasurement of high turbidities.
With both methods, the solid particles
in the medium cause the incident
light to scatter. The scattered light
thus generated is measured using
scattered light receivers. The turbidityof the medium is calculated fromthe amount of scattered light.
4-beam alternating light method
The method is based on two lights andfour detectors. Long-life light emitting
diodes are employed as monochromatic light sources. These light emitting
diodes are pulsed at a frequency ofseveral kHz so as to eliminate any
effects of extraneous light. With eachlight signal, two measuring signals aredetected by the four detectors. Eightmeasuring signals in total are processed in the sensor and converted tosolid concentrations. The 4-beamalternating light method allows users
to compensate for any fouling andaging of optical components.
Attenuation measurement
Attenuation measurement is also
performed in accordance with
ISO 7027. A light source radiates alight beam through the medium. The
detector is positioned in line with thelight source and detects the transmitted light. This measuring method issuitable for medium to highturbidities.

Scattered light methods: The scattered light
generated by solid particles is measured at

Oxygen sensors using the amperometric principle
When performing measurements
using the amperometric principle, thesensor comprises a working electrodeand a counterelectrode in the simplest
version of the two-electrode system.
Both are surrounded by an electrolytic
liquid in a common chamber.
A membrane provides the link to themedium or process: oxygen permeatesfrom the medium into the electrolyte
through the membrane and isconverted to a current at the working
electrode. The counterelectrodekeeps the system running bymeans of a chemical equivalence
reaction. The resulting current
response is in direct proportion
to the oxygen partial pressure.
The current is converted in thedownstream transmitter anddisplayed to the user in thefamiliar units of oxygen saturation,
concentration (in mg/l or ppm)
and oxygen partial pressure.

Oxygen measurement using the principle of fluorescence quenching
With the fluorescence quenching
method, a layer that is permeable tooxygen also forms the junction withthe process. This layer contains just as
many oxygen molecules as themedium (the partial pressure of theoxygen is just as high in the medium
as in the layer). It is separated fromthe optics at the sensor by means of a
substrate that is permeable to light.
The layer contains marker moleculesthat are optically excited with a green
light and respond with a red
fluorescence light.
Oxygen molecules adapt to thesemarker molecules and decrease(quench) the fluorescence lightemitted. The reduction in fluorescencelight is connected to the oxygen
partial pressure, both in terms of theamplitude and the duration. The lightsignal is converted in the downstream
transmitter and made available to theuser in the familiar units of oxygen
saturation, concentration (in mg/l orppm) and oxygen partial pressure.
In applications that involve higher

Experts in disinfection measurement
Disinfection solutions for all applications
Disinfection solutions play a particularly important role
in applications such as drinking water, industrial water
treatment and swimming pools. In these applications,the focus is on safe and cost-effective water treatment
and disinfection as a means of protecting people andsystems. An appropriate disinfectant is added to theprocess in a waterworks, swimming pool, cooling tower orbottle cleaning facility. Due to their powerful disinfectant
properties, chlorine and chlorine dioxide have establishedthemselves as the state-of-the-art solution available
worldwide. Ozone is often applied in the treatment process
in waterworks and bromine is suitable for salt water
applications such as ships' ballast water or fish farming.
Complete measuring points
The sensory mechanism uses the amperometric principle,
i.e. the disinfectant concentrations are converted toelectric currents in the sensor, which are then processedin the transmitter to obtain the required reading.
To do this, the medium (mostly water) is supplied
to the sensor via a flow assembly. The discharged
medium is either returned under pressure or directed
into the drain. This is referred to as a lost sample, amethod commonly used in the field of drinking water
for the prevention of all possible contamination.

Wide range of high-quality products
Endress+Hauser offers a wide range of sensors. Besides
the sensor for free available chlorine, sensors for chlorine
dioxide, total chlorine, free bromine and ozone areavailable. The highly automated production process
guarantees consistently high quality.
Testing is also performed on a fully automated testbed,
where the sensors are tested for zero point, slopeand constancy and the results are documented.

Benefits• Wide range of sensors: free available chlorine, chlorine
dioxide, total chlorine, free bromine and ozone• Easy installation thanks to complete measuring
panels with flow assembly• Simultaneous measurement of pH and ORP values,
conductivity and oxygen possible• High-quality products guaranteed

Video on amperometric measuring
principle for disinfectants

Chlorine measurement

Sensors for disinfection using the amperometric principle
The sensors work in accordancewith the amperometric principle
in a membrane-covered cell.
Their operation can be describedusing the example of chlorine
dioxide measurement:
The sensor includes a metallic working
electrode, which is separated from themedium by a thin membrane. Chlorine
dioxide coming from the medium
diffuses through this membrane and isreduced at the working electrode. The
circuit is completed by means of thecounter electrode and the electrolyte.
The electron reduction at the working
electrode is proportional to theconcentration of chlorine dioxide in
the medium. The transmitter converts
this current to the appropriate display

value. With chlorine dioxide, thisprocess works across a wide pH andtemperature range. The scenario withfree available chlorine is somewhat
different. In this case, hypochlorousacid diffuses through the membraneand produces a reaction. The presenceof hypochlorous acid in the medium
depends on the pH value.
This dependency is compensatedby means of pH measurementin the flow assembly andbalancing in the transmitter.
Total chlorine measurement
also includes bound chlorine,
i.e. chloramines, in addition
to hypochlorous acid.

Chlorine dioxide diffuses through themembrane and is reduced at the working
electrode

No contamination of feed waterHigh quality of boiler feed water is a key
factor to avoid corrosion or build-up of
deposits in boilers or pipes. These canlead to expensive repairs or even complete
unit replacement. Conductivity, pH andoxygen sensors, specially designed for trace
measurement, ensure that even minute
impurities in the demineralized feed water aredetected. Plant operators can react quickly
and take the necessary measures.
Safe cooling water cycles
Cooling water cycles must run stably and must
not interfere with the product. Contaminatedcooling media can cause corrosion or build-up
of deposits and thus leakage in the coolingwater cycle that leads to mixing of productand cooling medium. Conductivity, pH,
chlorine and SAC sensors ensure that
contamination is detected before problems
can occur.
Cooling water must be of sufficiently highquality to ensure that no microorganisms cansettle in the system. They form a biofilm on
the pipes that impedes the heat transfer andthus limits the cooling performance. Reliablechlorine measurement enables precise
chlorine dosing resulting in bacteria-freewater.
