What’s In Your Pipeline?

Author: David J. FishDownload File

With the current demand for improved technologies in the area of natural gas measurement, the rush to the market place is raising as many questions as it is answering. In the last 25 years, the natural gas pipeline industry has transitioned from the supplier of clean, dry gas to the mover of billable gas energy; […]

Electronic Calibrators

Author: Betsy MurphyDownload File

Electronic calibrators are fast becoming the benchmark for measurement and are replacing mechanical types of instruments for testing and calibration checks. Techniques, usage, traceability requirements, and problems are changing quickly as technology advances in the development of these instruments. Information concerning these issues is often outdated by the time the technician receives it. Electronic calibrators […]

Protection Of Natural Gas Measurement Equipment Against Moisture And Corrosion

Author: Donald P. MayeauxDownload File

This presentation addresses problems associated with moisture and corrosion caused by high relative humidity and airborne contaminants. By controlling moisture and corrosion long-term, many problems associated with sensitive field electronics can be avoided

Freeze Protection For Natural Gas Pipeline Systems And Measurement Instrumentation

Author: David J. FishDownload File

The failure to supply natural gas upon demand can cause irreparable damage to a company’s corporate image in the 21st Century. Consistent and continuous pipeline operations are key and critical factors in today’s natural gas pipeline industry. The competitive nature of the business, together with the strict rules and regulations of natural gas supply, mandate […]

Pulsation Reduction By Acoustic Filters For Metering Applications

Author: Robert J. McKeeDownload File

Because of the adverse effects of pulsations on orifice and other types of flow meters there is for many installations, a need to eliminate or decrease the amplitude of pulsations in the piping. This task has been the primary domain of acoustical piping designers who have had both theoretical and practical field experience in such […]

Pulsation Effects On Orifice Metering Considering Primary And Secondary Elements

Author: Robert J. McKeeDownload File

The use of orifices for commercial flow measurement has a long history dating back more than 50 years. Orifices are extensively used in the United States natural gas, petroleum and petro-chemical industries and are important as one of the most practical ways to meter large volumes of gas flow. These meters are very reliable and […]

Overall Measurement Accuracy

Author: Paul J. LaDownload File

This paper presents methods for determining the uncertainty of both differential and linear metering stations. It takes into account the type of meter, number of meters in parallel, type of secondary instruments, and the determination of physical properties. The paper then relates this information to potential influence on system balance

Problems Unique To Offshore Measurement

Author: Wayne T. LakeDownload File

As the worldwide demand for oil and gas forces offshore exploration into waters off the continental shelves into depths of over a mile deep, capital expense spending (CapEx) and production operation expense (OpEx) budgets are slashed and the Environmental Health and Safety (EH&S) requirements as well as some companies’ goals for a ‘greener image’ raises […]

A New Perspective On Measurement The Impact Of Measurement In A Changing Business Environment

Author: David WoffordDownload File

The measurement of hydrocarbons has evolved significantly through the years, from both a technical and business application perspective. Developments and advances in technology have made the measurement of hydrocarbons more precise, efficient and available. Changes in the energy business environment have placed the measurement of hydrocarbons into a more significant role within organizational and industry […]
