Dosing food oilsmoothly withina shorter time

Flow measurement –––––– Ensuring a consistent flavour/ Reliability is the key ingredient / In the industrial production of food, high-quality ingredients and uniform recipes
ensure a consistent product result. This is important because this product result is also a taste sensation. Whether it’sbaby food in a glass or remoulade in a tube: Businesses andcustomers expect each new batch of your product to taste
exactly like the previous one. A flowmeter helps you ensure
this by controlling the precise dosing of food oil.

23A food producer doses food oil from the storage tank to theimpeller type mixer. The challenge in this batch process is toensure that neither too little nor too much oil flows because
the recipe also changes the taste of the final product.

Flow measurement –––––– challenge

45/ It is all about the quantity / Whether you are processing
mayonnaise, potato puree or baby food: Your plant needs tomeasure and control the volume flow of food oil through thepipeline precisely.

Conventional solutions
Electromagnetic flowmeters (EMF) are not usuallysuitable: This is because the conductivity of manyoils is too low.
Mechanical flowmeters – such as paddle wheels oroval gear meters – do not meet the hygiene
requirements of the food industr y.
Conventional Coriolis measuring devices are lessenergy efficient due to the “tapering” of the pipeline.
This is because the pump has to work harder todeliver the same quantity of medium through thethinner pipeline.

Flow measurement –––––– solution

6/ Hygienic flow measurement with SAW technology / Forfood producers, hygiene is the top priority. Thanks to ourinnovative SAW technology, the FLOWave sensor measuresthe volume flow not only under completely hygienic conditions, but also independently of the conductivity of the oil.
The flowmeter made entirely of stainless steel does notrequire any sensor elements in the measuring tube. For
you, this ­m eans no pressure loss, no maintenance expenditure and a simple cleaning process.

FLOWave

SAW stands for Sur face Acoustic Waves. These occur in nature, e.g.,during seismic activities. We harness their effect in our patented SAW
technology for inline flow measurement.

Flow measurement –––––– added value

89/ Simply one tube / The complete FLOWave weighs only
slightly more than three kilogrammes – a single person can
install the handy flowmeter quickly and easily. It measuresthe volume flow hygienically and extremely precisely without
the use of sensors that come into contact with the medium
and independently of the conductivity. This saves you timeand makes your plant more efficient.

Maximum precision

Meets the highest hygiene requirements

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

FLOWave dispenses with sensors in the measuring
tube that come into contact with the medium. It
therefore measures the flow under completely hygienic
conditions. This is confirmed by various cer tificates(ASME BPE, 3A and EHEDG).

Consistent processes and product quality
Less loss, more productivity
The “Acoustic Transmission Factor” function detects
bubbles, par ticles or solids in the liquid. This allows
the user to inter vene quickly as soon as definedprocess variables are exceeded or undercut.

Thanks to the “density factor” function, FLOWave
detects fluid changeovers ver y quickly and simplifies
the separation of production steps. This reduces
waste and costs while increasing productivity.

Easy to handle and install
Fast start-up and easy operation
The compact and lightweight flowmeter fits into ever ysystem and is easy to install. At two inches in size, aFLOWave device weighs just 3.4 kg – compared to the70 kg heavy, two-inch Coriolis system.

Fit for the future
FLOWave devices utilise the Bürkert device platform
EDIP. EDIP stands for “Efficient Device Integration
Platform”. It considerably simplifies the handling of thedevices and helps to integrate them quickly into anexisting fieldbus system. In short: EDIP is part of ourcontribution to Industry 4.0.

The high-resolution 2.4“ display offers flexible
operation with intuitive, graphic user guidance. Freely
definable measured value designations and theoptional display of one to four measured values, atrend cur ve and the parameterisation inter face enable
an individually coordinated display. The WiFi module
allows remote access to measurement parameters via
web browser. This is par ticularly relevant when
FLOWave is installed at difficult-to-access points inthe process.

Flow measurement –––––– teamwork

10/ Systematic measurement / To ensure that the correct
quantity flows, the sensor, dosing valve and controller must
work in harmony. This is why Bürkert supplies you with apreconfigured system solution that you can simply integrate
into your plant. No matter whether you install the systemhorizontally, vertically or at an angle – we will provide youwith precise measurement results.

calculation

Measurably faster: How does flow measurement with FLOWave compare to a conventional Coriolis
meter? A customer takes the test: Soya nut oil flowed through the plant in each case with aviscosity of around 100 mPa /s. In contrast to Coriolis, FLOWave per forms measurements without
tapering of the tube and therefore with no loss in pressure. The volume flow is 30 times fasterwith FLOWave.
