Level measurement of a tank farm in beverage productionCoca-Cola HBC HungaryThe Coca-Cola Company is the world’s leading beverageretailer, distributing nearly 2400 products in more than200 countries all over the world. The Hungarian site ofCoca Cola Company in Dunaharaszti operates 2 bottlingand 10 regional distribution centres, employing morethan 1400 workers to meet its annual production capacityof one billion litres. Thanks to the previous successfulinstrumentation projects of NIVELCO – presented in the2010/1 issue of our Magazine – we received a newrequest in this year for providing further instrumentationsolutions for other tasks.Accuracy of this “measurement” was much less than therequired 0.5%, which is a general requirement insidethe factory for all measurement tasks. Therefore improvementof the instrumentation was necessary andsignificant in order to provide a safer environment in theaspect of OSH (Occupational health and safety) likewiseto increase the level of measurement technology.Tanks of the carbonated soft-drink production line inDunaharaszti were equipped with a low and high levelswitch and also an out-of-age visual level indicator.This solution was quite dangerous because the staff hadto use a 4–5 m tall ladder for reading the actual level.Regarding the customer demands and the neededmeasurement accuracy, we made an offer for acontinuous level measurement solution, for 17 standingstainless steel tanks, after a careful site-survey. We offeredfor this task our guided microwave MicroTREK radartransmitters. Further demands were the local displayof the measured values and centralised parameterisationpossibility of the transmitters. The obvious choice for thispurpose is the MultiCONT multichannel process controller.Summarisation and displaying of the measurement datais performed by a PC running the NIVISION processvisualisation software.24
