ASGMT has been providing Oil & Gas end-user personnel, manufacturing employees and university students the opportunity to obtain technical training from over 115 lecture classes and 48 hands-on equipment training classes.
Prior to the evolution of flow computers being commonly used in the measurement of hydrocarbons, most telemetry systems were used to collect control information and real time data and provide control commands to a Remote Terminal Unit at major pump and compressor stations. Most of the local metering was being handled by chart recorders and …

This paper is directed to ultrasonic natural gas meters using transit time across the gas pipe as the measurement variable. Custody transfer meters using sensors wetted with gas are the more familiar meter format. Clamp-on meters are quite similar.
What is a standard? Why are standards important? Merriam-Webster dictionary defines standard as: 1) “a conspicuous object (as a banner) formerly carried at the top of a pole and used to mark a rallying point especially in battle or to serve as an emblem” 2) “something established by authority, custom, or general consent as a …

Just when you thought you knew everything there was to know about Turbine meter measurement, wham, out comes a revised AGA 7 standard. Now those basic principles are all still valid but maybe those operating practices we have built into our operating procedures need a little review. Rather than proceed as generations have done before …
The measurement of gas has progressed considerably since the days of paper charts and manual integration. While still in use today, the technology has moved increasingly to microprocessor based flow computers. Such devices allow for greater measurement accuracy, increased control functionality, and are readily integrated into a company’s enterprise computer networks.
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 …
Turbine meters have been used for the custody transfer of refined petroleum products and light crude oils for over 40 years. When correctly applied, they offer high accuracy and long service life over a wide range of products and operating conditions. Traditionally turbine metes were used for the measurement of low viscosity liquids and PD …
In this paper I will attempt to give a fundamental overview of an NGL meter station design; however, it is not a straight forward, one size fits all scenario. 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 …

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 …
Natural Gas Liquid service was among the first applications for CDP or Captive Displacement Provers. CDP’s formerly called SVP’s or Small Volume Provers are used widely in natural gas liquid services. This paper will be focusing on operation and history of CDPS and thier advantages over the conventional type of Provers.
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.
