Flowmeters must satisfy numerous requirements in hygienic applications. Until recently, the necessary cleaning processes could only be conditionally realised as the liquids to be measured came into contact with sensor components whose influence often posed a process risk.
Bürkert’s FLOWave is a hygienic and safe flow measurement solution that offers numerous advantages for pharmaceutical and food production processes. It is suitable for the manufacturing and distribution of Water for Injection (WFI), pharmaceutical water, or ultra-pure water, as well as for CIP (Clean-In-Place) cleaning or filling processes for various fluids, including non-conductive media such as alcohol and edible oils.
With the FLOWave, Bürkert has taken an entirely new approach to flow rate measurement. Surface acoustic waves occur in nature during seismic activities. Bürkert has used these effects in a patented technology for inline flow rate measurement of liquids.
FLOWave is distinguished by its non-invasive design. Absolutely no sensor elements come into contact with the media in the measuring tube, resulting in clear application advantages over the entire product life cycle. As a result, issues such as seal failures, material incompatibilities and pressure drops are eliminated. This design also ensures optimal support for cleaning processes, eliminates the need for maintenance and guarantees100% wear-free operation.
The device functions independently of the liquid’s conductivity, expanding its range of applications. Its modular layout allows for maximum flexibility, including variable positioning of the display module and installation in any orientation. Compact and lightweight, FLOWave features low energy consumption and is equipped with a high-resolution 6 cm display for clear and precise readouts.
These devices meet the highest hygiene standards, are durable and resistant to disruptive influences such as vibrations and magnetic fields. The lightweight and energy-saving devices can be operated in any installation situation and aid in the qualification and validation of production, cleaning and sterilisation processes. By eliminating expensive maintenance work, FLOWave is able to reduce operating costs substantially.
With decreased thermal mass, heating and cooling times are quicker, which leads to accelerated processes and potential energy savings for CIP and SIP procedures, such as steam sterilisation. As a result, the productivity of your machines and systems improves.

Editor's Choice Flow Measurement & Control
There are many processes where it is undesirable for the load to suddenly change quickly, for example in the paper industry. Examples of level control have involved reasonably fast tuning. An example of a level loop tuned this way and responding to a step change in setpoint is given.
