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.
The purpose of this paper is to discuss in depth the systems we use as a standard to sample natural gas liquids, or NGL’s. Before we discuss the systems and methods used to sample these products, we must first clearly define what NGL’s are. NGL’s can be a combination of any fluid in liquid form …
This paper provides a fundamental overview of an NGL meter station design reviewing the nuances of configuring similar components in different ways. There are multiple considerations that influence the meter station design and all must be taken into account. Major considerations are: what product or products will be measured, what meter technology to utilize, and …
The measurement of natural gas liquids (NGL) is similar in many respects to that of other hydrocarbon liquids but is markedly different in other aspects. The main difference in NGL measurement is the need to properly address the effects of solution mixing.
Clamp-on ultrasonic gas flow measurement overview
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:
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.
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.
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.
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.
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.
ASGMT is dedicated to training, education, and creating a better future through the people who learn from us. As the largest gas measurement school in the United States, we are devoted to natural gas measurement, pressure regulation, flow control, and other measurement related arenas.
