REVIEW/ Hardware 6 Level control devices By Victor Zhdankin This piece launches a series of review articles covering level control devices and introducing readers to level sensors based on products from Pepperl+Fuchs GmbH. The articles examine the primary measurement devices and certain specific aspects of their use and would be useful for specialists in selecting the proper level sensor. SYSTEM INTEGRATION/ Oil and Gas Industry 20 Multifunction controllers as the foundation for mass automation of model oil drilling sites By Sergey Baltser, Grigoriy Bushkanets, Aleksandr Derkach and Vladimir Krasnykh The authors describe the creation of a model multifunction controller and its application in automating oildrilling sites at the Ashalchinskiy oilfield in Tatarstan. 30 New options for process control in oil extraction By Vasiliy Dudnikov, Damir Nabiyev and Vlad Gareyev This article examines the Mega automated control system. The article describes the structure of the system and the functions of its primary elements, and the authors cite those of the system's functions that are important for the oil extraction industry. 36 Gas6 gas content control system By Vladimir Kalabukhov, Aleksei Lyapkov and Victor Polyakov The authors examine the issues associated with automating separate sites along a gas pipeline using the Magistral2 technologies. The article provides a description of the Gas6 gas content control system, along with the structure of the sys- tem. This system is capable of functioning both as a compo- nent in a larger system or autonomously. DEVELOPMENT/ Oil and Gas Industry 42 The Khortitsa system for pipeline transfer By Aleksandr Romanovskiy, Aleksandr Grinenko, Gennadiy Solodovnikov and Vladimir Kuzminov This article describes a monitoring and measurement system intended for remote monitoring of parameters and control of equipment on gas and oil pipelines. 50 Automating bases for the storage of gasfilling stations By Victor Gusev, Boris Gorbatenko and Aleksandr Kuleshov The authors examine automated systems for controlling level, volume and mass of liquefied gases at a tank farm for the storage of gasfilling stations. The system is also capable of tracking the transfer of gas from a storage tank into tanker trucks and cylinders. 54 Automated system for dispensing liquefied gas at filling stations By Aleksandr Letunovskiy The author discusses the specifics of automating the retail and technical cycle of automobile filling stations, as well as the sys- tem developed for this purpose and the experience using the system. Particular attention is devoted to the metered dispens- ing of liquefied hydrocarbon gas. 62 Mobile unit for exploring gascondensate fields By Vladislav Dubinskiy and Tatyana Ivanova This article examines the issues associated with creating an automated monitoring and control system for a mobile explo- ration unit. The author presents the structure, main technical characteristics and functionality of the system. DEVELOPMENT/ Ecology 68 Automated environmental monitoring of surface water pollutant sources By Andrey Bodyazhin and Vyacheslav Trofanchuk The authors describe the Volga environmental protection boat, which provides environmental monitoring in the Kuibyshev reservoir. The article highlights all the components of the system, and it shows that the use of current technolo- gies to automate procedures for analyzing, collecting and processing information, with the ability to display and archive the information in real time, significantly increases the effectiveness of waterquality monitoring.
