The American School of Gas Measurement Technology (ASGMT) has been at the forefront of Flow Measurement training since its inception in 1966. Over the years, ASGMT has evolved to encompass comprehensive training in both gas and liquids measurement. With a commitment to excellence, ASGMT now offers an extensive curriculum comprising over 115 lecture classes, complemented by 48 Hands-On Product Training sessions led by industry experts.
Unaccounted-for gas can be defined as the “difference between the amount of gas purchased and the amount of gas sold through a measured gas distribution system.” This difference is commonly described as a percentage of gas purchased: “PERCENT UNACCOUNTED-FOR GAS.”
Timely, diligent field testing and calibration of gas volume recording and correcting instruments ensure that measurement information fairly represents actual volumes. The instruments save a company capitol and operating costs because they can record or integrate volumes at pressures and temperature above the normal pressurebase conditions specified in contracts for volume calculation. This allows the …

With the present day volatility in the price of natural gas, there is continued emphasis by gas producers, transporters, and distributors on accurate gas measurement at custody transfer points. Accurate metering ensures that both the buyer and seller are treated fairly and equitably in each transaction. Some of the other benefits of accurate measurement include …
After a decade of deliberation between government and the pipeline industry, the action of the Notice of Proposed Rulemaking requiring qualification for individuals performing covered tasks on a pipeline facility is a reality. The synergistic efforts of the members of the Regulation Negotiation Committee resulted in the authoring of an acceptable proposed rule, Qualification of …

Throughout the world, gas measurement utilizes two basic principles to measure gas volumes, positive displacement and inferential meters. Positive displacement meters comprise the large majority of measurement devices in use while inferential meters are used primarily for large volume measurement and thus fewer applications
Is a measurement being made good and is it as good as the measurement that was made yesterday, a week ago, or a year ago? The question of what is good measurement is asked all the time. This paper reviews what constitutes a good measurement. In addition it discusses the means that have been established …
Accurate and reliable gas measurement depends on a combination of efforts from two groups of people. First, we have the field personnel. They have the responsibility of seeing that a readable chart is produced and that all information pertinent to volume calculation is supplied to our next group, which is the office personnel. This group …
In recent years, chart recorders have started to give way to electronic gas meters at many locations. However, chart recorders are still being used at many sites and will continue to be used for the foreseeable future. The advances in computer processing that made electronic meters economical can also be used to enhance the reliability …
The measurement of hydrocarbon fluids, with an overall measurement accuracy that is acceptable to all involved parties, is a goal most gas measurement organizations strive to meet. The achievement of overall measurement accuracy can be visualized by using an image of a steel chain. One side of the chain is fastened to the true quantity …
An effective training program makes a significant impact on the bottom line of an organization. Volumes are relative to every purchase and sale of gas. Therefore, accurate volume measurements play either a direct or indirect role in the profitability of all the organizations in our industry. An effective training program is one of the best …
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.
