NIVELCO, as a prime contractorExpanding our profilewithin a local investmentCompanies in Hungary which have established commercialrelationships with NIVELCO in the past 30 years arepredominantly subsidiaries of some international (foreignbased)parent companies. According to the managementstrategy of these companies, they are trying to decreasetheir maintenance teams and operational personnel toa minimum.Consequently they are not able any more to implementmedium-size (compared to the size of the company)construction jobs within their own organization. Thereforethe implementation of these investment projects has beenperformed with the assistance of an outside contractor.In the case of new investments, the related organising jobis coordinated by the prime contractor - likewise there arealso many demands from the customer on completecommissioning of all smaller tasks. For the first time itshistory, NIVELCO acted as a prime contactor and madenew kinds of successes in this area. In the frameworkof the project detailed in the following, NIVELCO designedthe whole process controller system, of course usingmainly NIVELCO instruments.In the Industrial Park of Szentgotthárd, the Hungariansubsidiary of the American-based Allison TransmissionInc. (the world’s largest manufacturer of fully-automatictransmissions) established a new production hall.The key element of the production line is the oil containertank-farm with its complex instrumentation and electricalinstallation tasks.NIVELCO had to provide a complete solution, to includematerial specifications for the electrical system, andincluding wiring tasks, instrumentation and all accessoriesfor the process automation system. Finally the customerhas chosen NIVELCO thanks to the high technical levelof the offered solutions, especially the level instrumentation,the stainless steel control panels, and the galvanizedcable mounting structures. Moreover NIVELCO wasbeing proven as a reliable partner in the design of thecomplete technological implementation along with theprovided great price/value ratio. As a standard task, thecontinuous measurement of lubricant oil and emulsiontanks, and the control of filling-emptying pumps was alsodesigned and commissioned by NIVELCO. Since thefacility operates in a JIT (Just In Time) production strategy,any failure of the process control system hinders the productionseriously, so indication of alarm and warningsignals for the monitoring system was necessary.28
NIVELCO, as a prime contractorMeasurement solutionsMicroTREK HT-400 series guided radar transmittersmeasure the level in oil and oil-emulsion tanks.The control system continuously monitors the quantityof the homogeneous media, the level of each specifictank and the total quantity of the tank-farm, providinga reliable source of information for the filling andemptying processesMeasurement signals are processed by a MultiCONTmultichannel process controller in a HART multidroploop. HART communication facilitates centralizedsignal processing and provides easy access to changethe parameter-base of the product-specific technology.The local personnel decide which incoming materialshould be stored in which tank, based on the displayedvalues on the MultiCONT.Overfill protection on the tanks is achieved byNIVOMAG 210 4L magnetic level switches. To avoidthe possibility that any leakage may happen whenusing side-mounted equipment, the L-arm typeNIVOMAG was chosen for this reason. In additionto this, the required switching differential parameterswere easy to provide with this version.Leakage detection on the double-walled tanks is achievedby NIVOSWITCH RCM-400 vibrating forks.Thanks to the vibrating forks, the process controlsystem is able to indicate any negligible (comparedto the size of the tank) quantity (even a decilitre) ofleaking oil.Two UNICONT PJK-100 universal interface modulesare connected in the RS485 line, determining low andhigh fail safe level from the measured values, and thesemodules provide quick intervention if necessary.The filters and pumps used in the production plant arecontrolled by differential pressure switches. However althoughthese are not NIVELCO products, the measurementsignals from these instruments are also integratedinto the process controller system, therefore they are ableto indicate alarm signals. Also NIVELCO delivered the2 butterfly-valves which provide alternating filling for theemulsion-collecting tanks. Local electrical wiring and thestainless steel control panels were installed by a subcontractorpartner. The end users were fully satisfied with thequality of the finished project regarding as a great successfor NIVELCO’s local engineering team.Ákos NollRegional RepresentativeNIVELCO Co.anoll@nivelco.com29
