Measurement and Testing 37 Enhanced Version of Network-Based Control System Launched
Yokogawa Electric Corporation (Netherlands) has released an enhanced version of the STARDOM network-based control system. With this release, the integrity of the data transferred between supervisory control and data acquisition (SCADA) systems and programmable logic controllers (PLCs) is ensured in challenging upstream oil & gas and other applications.
The FCN autonomous controller and the FCN-RTU low power controller are core components of the STARDOM network-based control system, which is widely used in applications involving the monitoring and control of oil & gas fields, water supply facilities, and other installations that are often hundreds of kilometres apart. In such applications, the controllers installed at each site send data via a narrowband communications link to the SCADA system at a central control facility. To ensure that no data is lost, such systems generally employ DNP3, an open distributed network communications protocol. The STARDOM system has been enhanced to make better use of the functions supported by the DNP3 protocol.
With this enhancement, the FCN and FCN-RTU controllers now support a dual connection to DNP3 clients, enabling the same data to be sent to master and backup SCADA systems (the DNP3 clients) at the same time. When the same essential data is stored on master and backup SCADA servers in separate locations, the system can switch over to the backup SCADA server in the event of a disaster or some other eventuality that could cause the master SCADA server to go offline. This disaster recovery system ensures the uninterrupted monitoring and control of oil & gas fields, water supply facilities, and other types of infrastructure.
Takashi Nishijima, a Yokogawa Director and Senior Vice President of Yokogawa’s Industrial Automation Platform Business Headquarters, says: “Dating back to the days when the company introduced its flagship CENTUM system, Yokogawa has continually been focused on maximising system reliability, and this is one of the core values of our VigilantPlant initiative. We have adopted the same policy with our SCADA systems and are able to prevent the loss of valuable data and guarantee total consistency - even when data is transmitted between customer facilities that may be hundreds of kilometres apart. Yokogawa will continue to enhance the reliability of the systems that its customers and society depend on.”
Reader Reply Card No 120 TOC Analyser for Process Water
The QuickTOCcondensate is the online measurement system for the fast and precise determination of TOC in pure water of industrial processes. Its patented thermal oxidation technique at 1,200°C guarantees that all organic impurities are completely oxidised without exception and offers the added saving of negating the need of expensive catalysts, as with other high temperature methods. The totally sealed analytical system, maintained at an overpressure of 0.4 bar, means that the sample is measured without any environmental interferences influencing measurements. Furthermore, the well designed multi-loop injection system is small and compact. It has reduced internal dimensions and little wetted surfaces, as well as no dead volumes, which means that memory effects from previous measurements are prevented. The quick and easy calibration and validation of the LAR (Germany) analysers, alongside the advantage of the batch injection system which features an auto zero function, offers operators the assurance that their results are accurate.
Hence, the QuickTOCcondensate is the best solution for ultra pure and cooling water monitoring as well as boiler feed and condensate measurement according to international regulations. Reader Reply Card No 121
Reliable and Versatile Two- Component Analyser
White Paper on Instrumentation for Produced Water Endress+Hauser (USA) have released a white paper, “Instrumentation for Produced Water Applications.”
Produced water refers to any water brought up to the surface during oil and gas production, typically as the result of drilling, exploration and hydraulic fracturing. Before disposing or reusing the water, it must be treated to extract hydrocarbons and satisfy environmental code regulations.
Cleaning produced water costs 300 times more than cleaning municipal waste water and 3,000 times more than cleaning irrigation water. Since each water treatment system can vary based on the water quality and the environmental regulations for its reuse, there is no universal treatment process. Nevertheless, basic requirements must be met when dealing with produced water.
It is important for companies to understand these factors so that oil and gas production can be maximised while containing costs and complying with regulations.
This non-commercial white paper from Endress+Hauser explains where produced water comes from, how it is treated, and the instrumentation needed at every stage of the process.

The AMS 6000 from AMS (Analysen-, Mess- und Systemtechnik) GmbH (Germany) is suitable for measuring traces of oxygen and one
other parameter such as Co, H2 or humidity. An electrochemical measuring cell is integrated for
analysing O2, Co and H2. The residual moisture is determined by a ceramic sensor. Therefore it is possible to analyse more than one component at the monitoring station.
The AMS Two-Component-Analyser is equipped with electronic, pneumatically controlled components for gas removal and flow rate, installed in an electronic housing. The housing is produced according to AMS’ customers’ requirements. The AMS 6000’s numerous supplementary components include manual purge and bypass valve, sample gas pump, electronic flow monitoring, automatic calibration (remote control), automatic purging of the sensor or Ex-Zone 2 applicable. As a result of the different equipment we could deliver our analyser determined by our customer needs.
The AMS process analysers are manufactured according to stringent European standards. AMS also offer gas sample conditioning and additional analyser equipment to meet specific customer needs. Their instruments are supported by a reliable, worldwide spare parts supply though many partners located throughout the world who will also help with start-up assistance and training.
