Operational Aspects

The advantages of ultrasonic flow meters are well know — no line obstructions, large turndown ratio, bi-directionality, high accuracy — and ultrasonic meters are now widely used within the gas industry in a wide variety of applications. Ultrasonic meters are available in several different configurations ranging from high accuracy multipath spoolpiece meters to single path hot-tapped meters. While all of these meters operate on the same basic transit-time principle, there are significant differences in their operational aspects. This paper is intended to review the basic concepts of ultrasonic flow meters, to clarify the differences listed, and to explain how ultrasonic meters should be specified.

Regulatory Commission

Natural gas is an increasingly vital U.S. energy source that is presently being tapped and transported across state and international boundaries. Controversy engulfs natural gas, from the hydraulic fracturing process used to liberate it from massive, gas-laden Appalachian shale deposits, to the permitting and construction of new interstate pipelines bringing it to markets. This case explores the controversy flowing from the proposed 256-mile-long interstate Nexus pipeline transecting northern Ohio, southeastern Michigan and terminating at the Dawn Hub in Ontario, Canada. As the lead agency regulating and permitting interstate pipelines, the Federal Energy Regulatory Commission is also tasked with mitigating environmental risks through the 1969 National Environmental Policy Act's Environmental Impact Statement process. Pipeline opponents assert that a captured federal agency ignores public and scientific input, inadequately addresses public health and safety risks, preempts local control, and wields eminent domain powers at the expense of landowners, cities, and everyone in the pipeline path. Proponents counter that pipelines are the safest means of transporting domestically abundant, cleaner burning, affordable gas to markets that will boost local and regional economies and serve the public good. Debates over what constitutes the public good are only one set in a long list of contentious issues including pipeline safety, proposed routes, property rights, public voice, and questions over the scientific and democratic validity of the Environmental Impact Statement process. The Nexus pipeline provides a sobering example that simple energy policy solutions and compromise are elusive—effectively fueling greater conflict as the natural gas industry booms.

Regulation Reform

Industrial integration is the trend of the modern industrial economy. It is the result of the enterprises from competition to cooperation. Industry boundaries become blurring. And industries begin to integrate. With technological innovation, business integration, market integration, as well as industry regulation reform, electricity industry and natural gas industry is towards integration. The barriers between electricity industry and natural gas industry has been eliminated through knowledge sharing, mergers and acquisitions, market reform and regulation reform in developed countries. The energy industry in China will also be integration to improve national competitiveness.
