connecting the tank farm to the control room, with the added benefit of reducing implementation time as much as 60 per cent. Te savings free up budget for expanded automation of tank farms, says the company (Fig. 1).
Te Raptor system with smart wireless technology features a complete line of Emerson’s new state-of-the-art Rosemount tank gauging components, including high precision radar gauges that use self-configuring, two-wire, high speed Foundation Fieldbus technology. Te combined communications technologies enable use of a wide range of standardised equipment. Te resulting Raptor system forms a network of digital intelligence that improves inventory management, loss control, overfill avoidance, and maintenance efficiency throughout the plant. Many tank storage facilities that could benefit
from modern, non-contact gauging currently use obsolete signal wiring, or are not connected from the tank storage area. Retrofitting an obsolete gauging system is
expensive and time consuming because the distance between storage tanks and the control room can be more than one kilometre, requiring extensive trenching and cabling. As a result of budget restrictions, some plants continue to experience maintenance problems caused by communications limitations and low performing mechanical tank gauges and instruments. Now, with Smart Wireless technology, a new radar-based Raptor system can be installed without new long distance signal wiring. Tis will radically reduce material and labour costs, as well as engineering and project execution time.
“Te wireless-empowered tank gauging systems are effective in new installations or for upgrading existing sites,” commented Mikael Inglund, technical product manager, Emerson Process Management. “Our customers struggle with costs of replacing aged wiring, obsolete measurement instruments, and proprietary gauging systems. Our wireless Raptor systems give them the flexibility and freedom to implement an effective modernisation strategy. Tey can be changed out and wirelessly integrate new gauging systems one tank at a time. Most upgrades are done without taking the tank farm out of service.”.
Communications Emerson has also released Mobile Worker: Voice and Video, a communications technology designed to help process manufacturers save time and money on plant maintenance and trouble-shooting by bringing the problem to the experts rather than bringing the experts to the problem. In the face of reduced plant work forces, more experienced personnel nearing retirement age, and increasing travel costs, Emerson partnered with AudiSoft to deliver a hands-free, high-definition voice and video solution that plant personnel can wear into remote field locations anywhere in the world. From the problem area, the field engineer can
securely visually and verbally communicate live via a wi-fi access point, cellular, or satellite wireless connection with remote experts who, from their laptop or PC, can see and diagnose the problem, then instruct the field engineer through the problem’s resolution. ●
Instant data and voice communications I
n today’s competitive and highly volatile energy markets, it is imperative that oil and gas companies optimise their exploration and production activities. Fast decisions, facilitated by instant data and voice communications, are keys to sustained revenue generation and cost reduction. Much of today’s oil and natural
gas production occurs in largely remote areas of the world beyond the economic range of traditional wired communications. Oil and gas companies must regularly collect critical data from remote well sites, offshore drilling platforms, and outlying production locations, and

from SCADA systems set up to monitor facilities, such as storage tanks, pumping stations, or pipelines. Company personnel require training in high-speed voice and fax services, email and web browsing. Establishing the required broadband network links between multiple locations can be extremely difficult and cost- prohibitive, given that these activities generally occur where wireline links are not practical. Te answer to these business
problems is EION’s wireless broadband access infrastructure. Providing flexible and reliable wireless connectivity not only ensures reliable data, voice,
and video, but delivers a return on investment in short order - measurable by reduced costs and increased revenue, as well as peace of mind. According to EION, overall benefits include: eliminating the massive costs and deployment delays of traditional wireless solutions; quick deployment and reconfiguration; rugged enclosures for demanding applications; portability; high- throughput wireless network enables multiple applications including SCADA, internet access, email, voice- over IP, video conferencing and video surveillance; no wire clutter; and a proven track record. ●
