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 […]

Terminology Used In Instrument Accuracy

Author: Rick WilliamsDownload File

The purpose of this paper is to offer a brief explanation and discussion of many key terms used in describing instrument accuracy. The terms included within this discussion are most commonly used for defining performance standards with primary sensing elements typically used in the measurement of flow, level, pressure and temperature instruments. Many of the […]

Field Experience With Electronic Calibrators

Author: David L. ThomasDownload File

The use of electronic pressure calibrators in the gas industry has added new concerns and issues in pressure measurement. Readings appeared that perhaps didn’t match the old “reliable” standby calibration readings or methods, and terms like sensitivity, accuracy, resolution, stability and traceability have become common. Technicians began using correction factors to achieve standard conditions. These […]

D.o.t. Requirements For The Transportation Of Sample Containers

Author: David J. FishDownload File

The United States Department of Transportation (D.O.T.) is a department of the U.S. Federal Government which oversees all issues regarding transportation within the United States of America and U.S. Territories. Its influence around the world is great and widely respected, but its jurisdiction and power of enforcement is limited to the USA and its territories. […]

Automating Gas Measurement

Author: Richard L. ClineDownload File

Since the discovery of oil and gas and the advent of commercial conveniences, which use oil and gas, companies have been confronted with the need to accurately measure the oil and gas bought and sold in the marketplace. And, as usual, the technology available at the time was brought to bear on the measurement process. […]

Low-power Flow Computers

Author: Rick Heuer, Charles DerrDownload File

As we enter the second decade of use of Low Power Flow Computers (LPFCs), we do so with significantly different hardware, software, economics and motivating forces. These differences are worthy of close examination, as they ultimately will affect all of us in this industry. In order to focus on the majority of applications for LPFCs, […]

Electronic Transducers & Transmitters (new Trends In Measuring Natural Gas Flow Rates)

Author: John SchnakeDownload File

Traditionally, the flow of natural gas has been measured by a combination of pressure transducers, smart transmitters, and flow computers. In the earliest types of natural gas flow measurement, transducers and transmitters were connected to flow computers to calculate natural gas flow rates. In terms of the real measurements, these transducers and transmitters served as […]

Economics Of Electronic Gas Measurement

Author: Tom R. CheneyDownload File

There isn’t any one who isn’t impacted by the continuous growth and changes in the world of technology. In today’s world, we accept computers and the functions they perform without question. In fact, we place our hardearned dollars and in some cases our very lives in their care without a second thought. Computers and electronic […]

Fundamental Principles Of Rotary Meters

Author: Peter WalkerDownload File

Rotary gas meters have been in use for over sixty years in the natural gas distribution industry. Over the years the construction has switched from heavy cast iron bodies to lighter, high strength aluminum. Advances in manufacturing techniques such as CNC machining centers have enhanced the measurement performance of the rotary meter. Traditionally rotary meters […]

A New Perspective On Measurement

Author: Lohit Datta-BaruaDownload File

Everything we do must have business relevance or must add value. This is true not only for measurement process, but for every process we are involved in. One must constantly question our action and not fall in the trap of “that’s the way we have always done it.” This paper provides a new perspective on […]
