Food and beverage manufacturers usually process several products in a single plant. In batch process operations, rejects occur with every media changeover. With FLOWave, Bürkert has managed to develop a flowmeter that quickly detects any media changeover. In terms of your plant, this means: You reduce rejects and increase efficiency. Less product in the waste water also leads to less water treatment costs. Manufacturers of food products, such as milk, beer and lemonade, are already using FLOWave successfully.
Discover in the next section why FLOWave measures to optimum hygiene standards.
Efficiency is key – Regardless of whether you process milk, beer or lemonade: during normal operation, your plant should produce as efficiently as possible.
Hygienic flow measurement with SAW technology
Hygiene is particularly important in the production of food and beverages. FLOWave therefore meets high level hygiene standards. Thanks to innovative SAW technology, the flowmeter works without sensor elements in the measuring tube. No parts in the measuring tube means: no leaks, no material incompatibility, no maintenance, no pressure drop and easy cleaning.
Bürkert’s patented SAW technology uses surface acoustic waves to measure the flow of liquids. SAW stands for Surface Acoustic Waves. These waves occur in nature, e.g. as a result of seismic activities. Advantage of the measuring principle: It works without any sensor elements in the measuring tube that come into contact with the medium.
FLOWave: The 7 advantages you should know
Density factor: The decisive difference
FLOWave determines the density continuously. 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 fast and precise measurement reduces rejects and increases the efficiency of your plant.
In the example, two types of lemonade with varying sugar content are distinguished from each other: the lemonade with 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.
The density factor in practice
Fluent and profitable: 100 litres of liquid per minute flow through a DN50 pipeline. In conventional plants, the media changeover is time-controlled; due to the tolerance, the valve to the drain opens 15 seconds too early. With 5 media changeovers per day, around 125 litres of your product end up in the drain. FLOWave detects the media changeover faster, sends a message to the valve, which switches 10 seconds earlier, thereby protecting your resources and your budget.
