Flow measurement –––––– FLOWave SAW flowmeter / Type 8098

Measuring theflow fluently
for more profit.

Flow measurement –––––– For greater plant efficiency/ Is everything flowing the way you want it to? / Let us as­
sume that you process several products at a single plant inyour company. Be it milk or beer: above all, it is the quantitythat counts. After each batch process, you rinse the pipeline
with a cleaning agent. This mixes with your product – andcauses litres of waste. Furthermore, costs are incurred forwaste water treatment. A flowmeter that quickly detects themedia changeover reduces waste and increases the effi­
ciency of your plant. So that everything flows as it should.

A food or beverage manufacturer operates an efficient
production plant. It needs to run at full capacity to pro­
cess the wide range of products economically. The crucial
point: the efficiency of the plant is below expectations as
profit slips away with each media changeover.

Do you want to increase the efficiency of your plant? Read how easy thiscan be done in your plant on the following pages.

Flow measurement –––––– Challenge/ Efficiency is key / Regardless of whether you process
milk, beer or lemonade: during normal operation, your plantshould produce as efficiently as possible.

Media changeover

The pipeline has to be rinsed after each batch process. During the media
changeover, the cleaning agent contminates the product rendering it worthless.

Compatible

Regardless of whether
milk, beer or cleaning fluid: flow measurements
demand flowmeters that are compatible with arange of liquids.

Waste water treatment
Tipping product “down the drain” causes additionalcosts for wates water treatment.

Production plant

Electromagnetic flowmeters (EMF) can also be used tomeasure the flow of various liquids. However, if theyshould also detect the media changeover, they must becombined with additional sensors.

Coriolis flowmeters detect the media changeover, but
are expensive to purchase and difficult to handle due totheir size and weight.

Flow measurement –––––– Solution/ Flow measurement with SAW technology / Hygiene is thetop priority when producing food products and beverages.
FLOWave provides you with a compact solution that meetsstrict hygienic requirements. Thanks to innovative SAW
technology, the flowmeter dispenses with sensor elementsin the measuring tube. No parts in the measuring tube means:no leaks, no material incompatibility, no maintenance, nopressure drop and easy cleaning.

FLOWave

Surface acoustic waves (SAW) occur in nature, e.g. as a result of seismicactivities. We have harnessed these effects in a patented technology forthe inline flow measurementof liquids.

Flow measurement –––––– Added value/ Compact and clever / FLOWave not only measures the flow
rate, but also the temperature, density factor and acous­
tic transmission factor of your liquids. It therefore detects
media changeovers quickly and precisely. This is a gain foryour production plant: it works much more efficiently.

Maximum precisionLess loss, more productivity

FLOWave measures the volume flow independently of theconductivity of the medium with an accuracy of 0.4 % of themeasured value, the accuracy for the temperature is ≤ 1 °C.

Thanks to the “Density Factor” function, FLOWave detects fluidchangeovers very quickly and simplifies the separation of production steps. This reduces waste and costs while increasing
productivity.

Meets the highest hygiene requirements
Constant processes and product quality
FLOWave dispenses with sensors in the measuring tube thatcome into contact with the medium. It therefore measures theflow under completely hygienic conditions. This is confirmed byvarious certificates (ASME BPE, 3A and EHEDG).

The “Acoustic Transmission Factor” function detects bubbles,
particles or solids in the liquid. This allows the user to intervene
quickly as soon as defined process variables are exceeded orundercut.

Fit for the future
Fast start-up and easy operation
FLOWave devices utilise the Bürkert device platform EDIP. EDIP
stands for “Efficient Device Integration Platform”. It considerably simplifies the handling of the devices and helps to integratethem quickly into an existing fieldbus system. In short: EDIP isjust one way we addressing the challenges of Industry 4.0.

Easy to handle and install
The compact and lightweight flowmeter fits into every system
and is easy to install. A FLOWave device with two inches pipe
size weighs just 3.4 kg - compared to a Coriolis flowmeterwith 70 kg.

The high-resolution 2.4" display offers flexible operation with intuitive, graphic user guidance. Freely definable measured value
designations and the optional display of one to four measured
values, a trend curve and the parameterisation interface enable
an individually coordinated display.
The WiFi module allows remote access to measurement parameters via web browser. This is particularly relevant when FLOWave is installed at difficult-to-access points in the process.

Flow measurement –––––– Density factor

Flow measurement –––––– For more profit/ Wave goodbye to waste: Detecting media changeover, separating pro­duction steps / FLOWave continuously determines the density factor.
This is a temperature compensated measured value. If it changes,
FLOWave recognises that a different liquid is flowing. For example,
when milk turns into water at the end of a batch process. This fastand precise measurement reduces waste and increases the efficiencyof the plant. We illustrate it here using an example of water, milk andlemonade with varying sugar content:

Example calculation

Fluent and profitable: 100 litres of liquid per minute flow through a DN50 pipeline.
Conventionally, the media changeover is time-controlled; due to the tolerance, the valve to thedrain opens 15 seconds too early. With 5 media changeovers per day, around 125 litres of yourproduct end up in the drain. FLOWave detects the media changeover faster, sends a message tothe valve, which switches 10 seconds later, thereby protecting your resources and your budget.

12542litres of lost product per day(per production day)litres of lost product per day(per production day)Regardless of the temperature, FLOWave outputs a density
factor of 1.000 for water. If milk is added, the density factor
increases. The higher the density of a liquid, the higher
the density factor.
In the second example, two types of lemonade with varying
sugar content are distinguished from each other: the lemonadewith more sugar has a density factor of 1.025. The density
factor for the lemonade with slightly less sugar is 1.002. The
higher the sugar content of a liquid, the higher the den­sity factor.
