Memosens 2.0 - For simple, safe andconnected liquid analysis
The digital revolution in process analysis continues
Memosens technology has revolutionized liquid analysis. It
converts the measured value to a digital signal in the sensor
and transfers it to the transmitter via a non-contact
connection. This means that moisture and corrosion, which
distort the measured value or cause the measuring point tofail, don't stand a chance. Memosens sensors store sensor,calibration and process data in the sensor head enabling
real plug & play and pre-calibration of the sensors in thelaboratory.

The result is a dramatic increase in the availability of yourmeasuring point and a guarantee that your process will run
safely.
Memosens 2.0 is leading Memosens technology into thefuture. The extended sensor electronics offer:• Perfect basis for IIoT connectivity: You always have therelevant information on your measuring point close tohand using the right app.
• Predictive maintenance 2.0: The storage capacity for up
to 8 times more relevant data is an excellent basis forpredicting 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 Ex-approved
Liquiline transmitter.

With Memosens accessories, you can benefit from easy management of yourmeasuring points and sensorsValidation, qualification and maintenance of Memosens
measuring points using Memocheck
Memocheck tools simulate measured values and ameasuring error for the qualification of digital datatransmission. Memocheck establishes if deviant
measured values are caused by factors other than thesensor e.g. the cable and coupling, the connection to
the process control system or transmitter. You canrest assured that the measured values will always betransferred correctly, resulting in more process safety.
Using the Memobase software for measurement,calibration and documentation
The Memobase software supports your sensor andmeasuring point management. With this software, notonly can you calibrate the sensor and read out sensor
data, but you can also generate reports on the history
and status of a sensor, with measuring data, calibration
data and the sensor life cycle made visible at a glance.
Your process becomes transparent and the traceability istaken to a whole new level. In addition, the Memobase
software can be used in conjunction with a standard
PC as a measuring station in a lab, thus improving
the comparability of lab values and process values.

Calibration with quality buffers
Correct calibration is the be all and end all when it comes tothe accuracy of a pH measuring point. Our permanentcalibration laboratory for quality pH buffers has successfullycompleted the exacting accreditation procedure laid downby the German Accreditation body (DAkks) in accordancewith DIN EN ISO/IEC 17025:2005. Our customers can rest
assured that their pH measurements will always beaccurate.

and easily, and cleaning can be
carried out without interrupting
the current process. The sensor
can be inserted in the process
and removed from the process

either manually or automatically(pneumatic procedure).
Pneumatically operated
assemblies can be combinedwith automatic cleaning andcalibration. Retractableassemblies are particularly
suited to hygienic or heavy-duty applications, wherever
regular cleaning is required,or in cases where the sensor
can come into contact with anaggressive medium for shortterm measurements only.

From sensor to complete turnkey solutions

The Memosens sensor family includes sensors with an
inductive plug-in head or a fixed cable. The latter typedoes not require either regular recalibration or maintenancemeasures. All sensors use the standardized, digital
Memosens protocol which allows for easy and fast
operation. In addition, sensors with a plug-in head are
fully resistant to corrosion and salt bridges, thanks to thenon-contact, inductive transmission of data and energy.

Turbidity sensors
Optical turbidity sensors areused mainly in the treatment ofwater and wastewater. They offer maximum accuracy in drinking water in accordance with
ISO 7027 and robust measurement in municipal and industrial
wastewater due to compensation
for soiling and aging.

are available in amperometricor optical versions. The
amperometric principle ischaracterized by stablemeasurement across a widemeasuring range. The opticaltechnology impresses with its
high level of availability and low
maintenance.

Sensors and spectrometers fornitrate, SAC, COD, BOD, turbidity
These optical sensors allow measurement directly in the medium,thereby enabling early detectionof load peaks. Spectrometers
allow the determination of allparameters mentioned with only
one sensor. They are suitable for awide range of process conditions
in water and wastewater treatment and require very little maintenance thanks to an automatic
compressed air cleaning system.

Nitrate and ammonium sensors
These ion-selective sensors
offer prompt determination ofconcentrations thanks to online
measurement directly in thebasin. They therefore enable
fast, load-dependent aerationcontrol.

Modular immersion assemblies
These types of assemblies offer
flexible installation in immersion
applications such as those in
the wastewater industry. They
are suitable for sensors withdifferent connection threads.
This means that they are not
only used for 12 mm sensors

for the measurement of pH ordissolved oxygen but are also
used for turbidity or nitratesensors. The system can beinstalled using different pipes,
brackets etc. in almost any
location (pipes, rails etc.).

Flow assemblies
Flow assemblies are used for
installation in process pipes orbypasses. These configurations
are often found in waterworks,
in the beverage industry, thechemical industry or in analyticalcabinets in power plants.
Thanks to a range of processconnections, these assemblies
