Constant layer thicknesses with automatic control of the powder quantity With Flowsense, J. Wagner GmbH is launching a smart, digital system that measures and fully automatically controls the powder output. The result: Consistently high-quality results and reduced powder consumption from constant layer thicknesses.

As part of Wagner’s Flowsense technology, each individual feeding element is equipped with high-precision measuring sensors. The smart system constantly monitors the powder flow and compares the powder quantity with the target values. Flowsense can even measure the powder output in g/min and individually for each gun. The exact dosing of the powder quantity can be saved in the recipe and is permanently reproducible, as claimed by Wagner, without any manual corrections, which would be necessary without Flowsense. CONSTANT LAYER THICKNESSES In powder centres without Flowsense, the user has to monitor the powder quantity themselves to be able to readjust it in good time. The so-called sawtooth effect occurs to varying degrees and leads to uneven powder output during production. With Flowsense, however, the output parameters are adjusted independently and deviations are corrected automatically. The system even compensates for influences on the
output, for example, caused by fluidisation and fluctuating powder levels. The sawtooth effect is smoothed out by the control to a micro- sawtooth that can no longer be measured. The powder output can be adjusted much better to the target layer thickness, which in turn minimises the safety margin. This enables powder savings. Constant coating thicknesses within certain limits are also an important criterion for certification by quality associations for industrial coating. EXTENDED SERVICE LIFE OF WEAR PARTS Another advantage is predictive maintenance: As Flowsense permanently monitors the powder flow, blockages, for example, are detected in good time and rejects are avoided. In combination with the injector technology, Flowsense also provides information on the current status of the collector nozzles. This is clearly visualised on the touchscreen of the powder centre in a traffic light system. This allows the user to keep an eye on the exact system status at all times and provides continuous information on whether the coating

can achieve the desired quality. This allows the user to replace the collector nozzles quickly and exactly when it is actually necessary.
SIMPLER OPERATION AND INTEGRATION WITH IOT
Flowsense is configured and operated on the powder centre’s touchscreen with intuitive user guidance. Flowsense works mainly in the background and automatically displays relevant information. The smart system will also be integrated into Wagner’s COATIFY information and management platform, which can be used to intelligently visualise each user’s coating system. With detailed knowledge about the system status and information about which recipe can currently be reliably produced, the user can control production in a cost-optimised and sustainable way. P
