The American School of Gas Measurement Technology (ASGMT) has never turned its back on change since its founding in 1966. Instead, it has consistently embraced progress and pursued new ways to strengthen our industry and support the development of our students. This year is no exception. After 25 years at our previous venue, ASGMT has proudly relocated to The Woodlands Waterway Marriott Hotel and Conference Center. This move underscores our continued commitment to remaining at the forefront of industry evolution and delivering the highest‑quality experience for our students and the broader measurement community.
In order to understand the chemistry of natural gas, it is important to be familiar with some basic concepts of general chemistry. Here are some definitions you should know: Matter – anything that has mass and occupies space. Energy – the capacity to do work or transfer heat. Elements – substances that cannot be decomposed …
The use of Liquid Ultrasonic Meters for liquid petroleum applications such as custody transfer or allocation measurement is gaining world wide acceptance by the Oil Industry. Ultrasonic technology is well established but the use of this technology for custody transfer and allocation measurement is relatively new. Often users try to employ the same measurement practices …

The use of ultrasound in flow measurement began in the last century when, in 1928, Oskar Rütten patented this method and apparatus for measuring the volume of flowing liquids, gas, and steam. The first ultrasonic flowmeters were introduced in the 1950’s, and in the 1960’s different companies developed the first ultrasonic flowmeters using the differential …

This paper is to discuss the various methods of gathering electronic gas measurement (EGM) data. There are various options when it comes to collecting EGM data in the Natural Gas Industry. Devices such as RTU’s, PLC’s and EFM’s are typically used to collect and store the data locally. The focus of this paper is on the various technologies used to remotely gather the information stored on these devices. Depending on each company’s needs, these collection options could range from someone physically connecting to a device to collection via a satellite system. Spread spectrum networks became increasingly popular over the years, which as a result introduced realized interference due to the number of networks installed. Many companies are utilizing IP technologies versus serial in order to combine other networks and protocols. Licensed networks have been utilized for quite some time and are still used to meet reliability requirements. Cellular networks are often used when there is no infrastructure available in that area. Cellular networks will of course have a reoccurring cost associated with them. Satellite technology is required in some remote and/or saturated areas. Satellite communications can be costlier but is the only option available in some areas.
The majority of all gas measurement used in the world today is performed by two basic types of meters, positive displacement and inferential. Positive displacement meters, consisting mainly of diaphragm and rotary style devices, generally account for lower volume measurement. Orifice, ultrasonic and turbine meters are the three main inferential class meters used for large …
In the gas industry a standard unit of measure is required. In the English system it is the standard cubic foot. In the metric, it is the standard cubic meter. This standard unit is the basis of all exchange in the gas industry. When the unit of purchase is the energy content (BTU) we achieve …
Gas chromatography is one of the most widely used techniques for analyzing hydrocarbon mixtures. Some of the advantages of chromatography are the range of measurement (from ppm levels up to 100%), the detection of a wide range of components, and the repeatability of the measurements. Chromatography is used in the laboratory, in permanently installed online …
Much effort is spent to achieve accurate measurement. Up to date measurement standards, modern meter station design, high quality equipment, and proper measurement operations are all necessary for measurement accuracy. Unfortunately, these processes do not assure measurement accuracy if the contract does not also support accurate measurement. The contract impacts measurement accuracy by what it addresses and what is left unaddressed. More focus needs to be applied to the measurement sections of the contracts. Hopefully this paper will help the reader better understand the relationship between the contract and accuracy.
This paper presents fundamental information necessary to understand and appreciate the concept of total gas energy in a natural gas pipeline. That is, to be able to converse with peers within the natural gas industry and understand basic concepts and terminology. Discussed is the historical transition from volumetric measurement to total gas energy including some …
Electronic flow measurement as applied to the natural gas industry has advanced considerably over the last 30 years. Applications to address Upstream, Midstream and Downstream gas measurement technologies have become more complex. Over time it has become necessary to understand the fundaments that make up this ever-changing environment. This paper will discuss the important fundamental …
