Smart vertical farming in bigcities
Cost-efficient and intuitive
monitoring of nutrient supply

Culture racks in a vertical farming section to grow vegetables in minimal space. Continuous
monitoring helps to increase the product yield and save costs.

Benefits at a glance:• Compact and spacesaving installation• Simple monitoring of themeasured values with
the SmartBlue App• Low maintenance thanks
to intuitive handling at
every measuring point

Our cities are getting crowded whichputs pressure not only on living
space but also on agriculture.
Thanks to vertical farming cultures,
it is possible to grow freshvegetables such as cabbage andlettuce even in small spaces in bigcities all over the globe.
To save money and generate thehighest possible product yield invertical farming, optimal dosing of
nutrients is essential. This process
can be precisely controlled bymonitoring different parameterslike pH and conductivity.
Customer challenge
In many cities, space is limited andfresh vegetables need to be grown in
the tightest of spaces. Thererore, theplants are cultivated in racks which
are placed one above the other. Thebiggest challenge is to supply theplants with an ideal amount ofnutrients, as little as possible and asmuch as necessary. This keeps costs
low without reducing the expected

product yield. In keeping with theprinciple of sustainability, the excess
plant nutrient solution is collected andprocessed for reuse. In this step, boththe pH value and the conductivity ofthe medium, must be analyzed inorder to meet the quality
requirements.
For operators of vertical farming
systems, it very important that themeasuring systems are easy andintuitive to install and maintenance isas low as possible.
Our solution
To ensure a comprehensive
monitoring of processes, measuringsystems are installed in various areasof a farm. They are equipped withliquid analysis sensors for pH andconductivity and Liquiline Compact
transmitters. Liquiline Compact CM82transfers the measured values to theSmartBlue app, enabling easy
monitoring of the processes andintuitive sensor calibration via acommon smartphone or tablet.

Easy calibration with the SmartBlue App

pH sensor Memosens CPF81E andconductivity sensor CLS21E

The racks are supplied with nutrient solutions
to ensure optimal growthThanks to the Plug and Play function
and Memosens Technology, thesensors can be connected andexchanged easily via plug connection.
In addition, the water quality in thenutrient buffer tank is monitored.
Besides the analytical instruments,
the level sensor Mircopilot FMR10 isused for level measurement in thetank.

• Easy operation: After training, theuser can control the operation andmaintenance via the SmartBlue App
with a common smartphone. The
same equipment at all measuring
points makes operation andhandling even easier.
• Secure Bluetooth® connection: Theconnection is particularly secureand ideally protected against
unauthorized access by thirdparties. The Fraunhofer Institute forApplied and Integrated Security(AISEC) has confirmed that thesecurity requirements have beenmet.
• Simple monitoring of the measured
values with a smartphone.

All benefits at a glance• Space-saving and easy installation
to block as little usable space aspossible: The compact Liquiline
Compact transmitter takes upalmost no space.
• The Memosens Technology
guarantees secure datatransmission and high measuring
point availability thanks to thenon-contact, inductive coupling.
