80 GHz present for exact degree measuring in well-known German household brewery It’s no secret that the per capita consumption of beer has been declining for years and that breweries must give you new concepts to remain aggressive. The household brewery Ketterer in Hornberg invests quite a bit so as to have the ability to brew their beers with the best potential high quality and effectivity. The latest mission needed to do with degree measurement within the numerous tanks of the brewery.Assist with measurement know-how comes from the neighbouring valleyVEGAPULS 64 assumes the duty of content material measurement.Greater than 20 years in the past, Ketterer grew to become conscious of VEGA, the method instrumentation provider primarily based within the neighbouring Kinzig valley. That was when a degree measuring system was put in in a spent grain silo. It was mainly only a easy level degree measurement. One after the other, new measuring factors have been launched over time, together with full and empty alarms within the cleansing methods and VEGA degree sensors within the giant fermentation and storage tanks. Greater than the rest, it was the growing hygienic necessities on tanks that compelled the upgrading and extension of the measuring tools. All fermentation and storage tanks have been rebuilt, one after the opposite, to permit them to be cleaned higher. Immediately, VEGA sensors are utilized in many locations within the plant, e.g. within the CIP methods, within the brewing water tanks, within the storage tanks in addition to within the fermentation tanks within the brewhouse. In some they function an overfill safety system, in others they assist exact stock measurement. They’re additionally an integral a part of your entire course of management system.Dependable degree measurement regardless of foamThe 14 giant storage tanks, by which the 13 totally different beers mature, are additionally outfitted with VEGA sensors. The tanks are used optionally as strain, storage, fermentation or mixing tanks. For a very long time, VEGAPULS 63 was used to offer actual degree knowledge, however the assorted internals: spray heads, conical tank backside and pumping strains for mixing shandy.Further strain sensors are used within the CIP tank.Nonetheless, the blended drinks typically generated extreme foam, which led to measurement inaccuracies. As a consequence of this drawback, the VEGAPULS 64 radar degree sensor, which measures with a transmission frequency of 80 GHz and has a lot better focusing, was really helpful for this measuring level. Its beam angle is barely 4°. This permits the sensor for use even in vessels with inside installations or heavy buildup on the partitions, as a result of the beam merely passes by such obstacles. The very giant dynamic vary of VEGAPULS 64 ensures that measurement certainty is far larger, even in case of froth, extraordinarily turbulent product floor, condensation or buildup on the antenna. The sensor merely measures proper by way of the froth.View of VEGAPULS 63 on one of many storage tanks.The brewers have been fairly happy with the newly put in sensor, not solely due to the extra reliable measured values, but in addition due to the excessive accuracy of +/- 2 mm.On the whole, sensors within the brewery have to face up to quite a bit. The tanks are cleaned with chilly water, however sometimes sizzling steam can also be used. The strain sensors within the pressurized storage tanks, which examine the CO2 content material, additionally must be sturdy. Their measurement knowledge is essential for the following filling course of, as in any other case excessively sturdy foam era would happen. These sensors have been typically broken (strain blowout) through the cleansing processes. Because the ceramic measuring cells from VEGA have been in use, the measuring factors are working with none breakdowns.Conclusion and outlookKetterer Zwickel Pils gained the gold medal within the class “Zwickelbier/Kellerbier” (beer sometimes not clarified or pasteurized) on the “World Beer Cup 2012” in San Diego.Ketterer wish to develop using precision degree measurement within the plant. The corporate primarily based within the Black Forest nonetheless has tanks with none degree measuring units and it’s, after all, an actual drawback that they’ll’t but measure their content material as merely and elegantly as within the new buffer tank. Not each tank might be retrofitted with instrumentation, however it’s sure that new tanks might be – with radar degree sensors from VEGA. And why? As a result of – as Ketterer firmly believes – dependable degree measurement makes work quite a bit simpler.
