Uncompromising flow rate measurement
Innovative flowmeter for applications with the highest
hygienic requirements

“Just a single tube”

Flowmeters must satisfy numerous requirements in applications with hygienicrequirements. Until recently, the necessary cleaning processes could only beconditionally realised. The liquids to be measured came into contact with sensor
components whose influence often posed a process risk.
The FLOWave flowmeter from Bürkert opens up entirely new possibilities for hygienic
and process applications. With its unique SAW technology (Surface Acoustic Waves),
the device has no sensor elements in the measuring tube and makes it easy to fulfilvery high hygienic requirements.

FLOWave at a glance• No sensor components comeinto contact with the medium.
This means:– No seal problems– No material incompatibilities– No pressure drop–C
 leaning processes areoptimally supported–N o maintenance work

2FLOWave• The measurement is not dependent
on the conductivity of the liquid• Modular layout for the greatest
possible flexibility (variable­positioning of the display module,
arbitrary installation position)• Light weight, small dimensions• Low energy consumption• High-resolution 2.4" display

Intuitive user interface
A flexible user interface with intuitive, g­ raphic
user guidance, which can be adapted toindivi­dual needs, makes commissioning andopera­tion of FLOWave devices particularly easy.

Hygienic and safe
Thanks to their special design, FLOWave devices arepredestined for applications with the highest demands
on hygiene and cleanability.
The design has convincing features like …
• a measuring tube without sensor elements coming
into contact with the medium• the all-stainless-steel design with the highest
surface quality• no screws or other connecting elements

Simple and efficient
FLOWave devices are based on Bürkert’s own
EDIP electronic platform. EDIP stands for the‘Efficient Device Integration Platform’ of the new
Bürkert product generation with common userinterface and digital communication, which not only makes using thedevices considerably easier but also allows for extremely simple integration
into existing field bus systems.

Flexibility thanks to modularity

The most innovative measuring principleWith their modular design, FLOWave
flowmeters provide outstanding
performance in every installation
situation. In addition, you can adjust theposition of the display according to your needs:
on top or in the front, and it can be pivoted in
90° increments.

Surface Acoustic Waves (SAW) occur in natureduring seismic activities, etc. We have used theseeffects in a patented technology for in-line flowrate measurement of liquids. According to theprinci­ple, there are absolutely no sensor elements
coming into contact with the media in the measuringtube. Along with the measurement of flow rate andtemperature, FLOWave is extended in the next stepwith additional measurements such as density andmass flow.

Surface Acoustic Waves (SAW) occur in nature during seismic activities, etc.
We have used these effects in a patented technology for in-line flow ratemeasurement of liquids. According to the principle, there are absolutely
no sensor elements coming into contact with the media in the measuring
tube, and clear application advantages are provided over the entire
product life cycle.

A flexible user interface with intuitive, graphic user guidance, which can beadapted to individual needs, makes commissioning and operation of FLOWave
devices particularly easy.
FLOWave offers you the greatest possible flexibility on the high-resolution 2.4" display.
Freely defined measurement names and the optional display of up to four measurements,
a trend curve and the parameter interface enable a display customised to yourrequirements. The intuitive user interface facilitates navigation and orientation in themenu system.

SAW technology
Interdigital transducers* are triggered by an electrical signal andgenerate the surface acoustic waves. These waves spread overthe pipe surface and couple into the liquid at a specific angle.
The waves thereby generate reception signals with single andmultiple passes through the liquid. This takes place both withand against the flow direction. The run-time differences areproportional to the flow rate. The comparison of single and multiple
waves running through the liquid enables excellent measurement
performance and additional evaluations with respect to the type andcharacteristics of the liquids.

* Interdigital transducers are provided to generateand detect surface acoustic waves.

Our EDIP platform

FLOWave in day-to-day use

After mechanical production systems were established worldwide, followed bymass production and process automation, the concept of “Industry 4.0” stands
for the consistent digital orientation of industrial processes. With the introductionof the new device platform EDIP (Efficient Device Integration Platform) Bürkert
opens the door to intelligent networking of its products. This platform comprises
numerous functions, compatible HMI devices and other innovative services tofacilitate the system integration of new devices.

Specific processes are controlled based on flow rate measurements for theproduction of pharmaceutical agents and in all clean utilities applications.
This is where FLOWave is superior to conventional flow rate measuring
devices and technologies.

EDIP basic functionalities• User-friendly operating and display concept• Simple transmission and saving of device settings• Quicker and simpler commissioning• Access to detailed device diagnosis via the digital interface• The modular setup enables adaptation of the devices toindividual application requirements• Quick and simple parameter transmission with exchangeof the storage medium for service tasks• Local software updates

SOFTWAREtool
Bürkert Communicator
The Bürkert Communicator enables parameter settings
and access to comprehensive diagnostic functions.
All measurements are available and parameter settings
can be modified as an alternative to access via thedisplay module. This Windows-based software can be
downloaded free of charge from the Bürkert website.

Accessories Set
USB -/CAN-interface
The Bürkert system bus interface (büS) enables
connection of FLOWave to a PC. It is based on
CANopen, however, it works with auto-addressing
and without a master in the system. The accessories
set includes all necessary components for quick
and convenient commissioning.

The devices meet the highest hygiene standards and are durable and resistant todisruptive influences such as vibrations and magnetic fields. The lightweight andenergy-saving devices can be operated in any installation situation and aid in thequalification and validation of production, cleaning, and sterilisation processes.
By eliminating expensive maintenance work, FLOWave is able to reduce operating
costs even further.
