This paper is intended to provide meter station designers with a basic methodology for selection of an appropriate flow meter (or meters) for a given application. Since many applications require that a meter station operate over a broad range of flow rates or loads, an example is provided on how to address system rangeability while …

Like any other piece of equipment, a measurement artifact must be maintained. Obviously, it has to be in working order in general. However, what is more important is that it be operating within specified parameters and providing measurements that are traceable to a known source or sources.

There are many in our industry who would consider the advancement of the ultrasonic meter to be one of the most important
improvements in gas measurement in the past twenty years.

With the proliferation of horizontal drilling allowing access to tight oil formations, liquid production in the U.S. has
significantly increased over recent years. Consequently, there is renewed interest in accurate measurements for both custody
transfer and allocation purposes. Advances in measurement automation have yielded operators’ savings in the millions of
dollars annually.

This paper summarizes a SCADA implementer’s perspective regarding the intent of the Pipeline Hazardous Materials Safety Administration’s (PHMSA) Control Room Management (CRM) rule.

There is no substitute for well maintained, properly installed, and properly performing measurement equipment. Industry-
standard measurement equipment installation, operation, and maintenance provide the raw data necessary for those dealing
with natural gas liquids (NGLs) to transact business. Then, this raw data can be adjusted or converted to values suitable for
transactions to take place and for proper accounting.

The American Gas Association published Report No. 9, Measurement of Gas by Multipath Ultrasonic Meters 2
nd Edition
[Ref 1] in April 2007. Report 9 details recommended practice for using multipath gas ultrasonic meters (USMs) in fiscal
(custody) measurement applications. This paper reviews some of the history behind the development of AGA Report No. 9
(often referred to as AGA 9), key Report contents, which includes information on meter performance requirements, design
features, testing procedures, and installation criteria. This paper also discusses changes that were incorporated in the latest
revision.

The speed of sound in natural gas is the velocity a sound wave travels in the gas. There are a number of gas properties that affect the speed of sound and they include the composition of the gas, the pressure of the gas, and the temperature of the gas.

Can the effectiveness of skills training be measured? A Region Director friend of mine who works for a large natural gas pipeline company complained that his new measurement employees (new hires and experienced personnel that have transferred into gas measurement) are not performing required tasks and activities to his expectations.

The Natural Gas and Oil industry is continually driven by cost cutting measures and the need to gain more operational efficiencies and visibility to regulatory requirements. This paper summarizes a solution in which wireless instruments integrate with other conventional equipment to offer a rapidly deployable advanced well optimization system.
