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.
This paper provides an overview of the recently released Gas Quality Management Manual [1] that was developed by the American Gas Association Transmission Measurement Committee over a period of roughly seven years. The manual pulls together a wide range of information and provides context that allows both the expert and the novice to understand the …
One of the most common measurement errors and the most difficult to identify in natural gas metering systems is that caused by pulsating flow. It is important to understand the effects that pulsations have on the common types of flow meters used in the gas industry so that potential error-producing mechanisms can be identified and …

Natural gas companies in all segments – upstream, midstream, transmission and distribution -have deployed Electronic Flow Measurement (EFM) devices on a massive scale. Since the information contained within the EFMs is crucial to the company’s operations, robust and reliable systems to communicate with EFMs are required. The EFM data needs of some departments are mission-critical. …

The measurement of hydrocarbons has evolved significantly through the years, from both a technical and business application perspective. Developments and advances in technology have made the measurement of hydrocarbons more precise, efficient and available. Changes in the energy business environment have placed the measurement of hydrocarbons into a more significant role within organizational and industry …
The knowledge base from a field measurement technician to the measurement analyst is extremely demanding. Every field technician is tested in both knowledge and skills on a daily basis regarding: Electronic controls to pneumatic controls x Communication system support Multiple technical disciplines x Support of measurement equipment Procedures that must be followed (SOP) – Standard …

The condition of gas as it presents itself in the pipeline is often not ideal for accurate measurement, by an orifice flow meter. It is the requirement of the American Gas Association (AGA) that the natural gas be in a single phase and with a swirl-free fully developed profile as it passes across the orifice …
Measuring natural gas is both a science and an art. Guidelines and industry practices explain how to accurately measure natural gas. The ‘art” comes in trying to minimize errors and prevent measurement problems. However, sometime it’s easier to explain “how not” to measure gas when reviewing measurement errors. Measurement errors can be caused through poor …
This paper described the current contents of the United States orifice flow metering standard – American Petroleum Institute (API) Manual of Petroleum Measurement Standards (MPMS) Chaper 14.3, “Orifice Metering of Natural Gas and Other Related Hydrocarbon Fluids”, Part 2, “Specification and Installation Requirements.”(1) This document is also knows as American Gas Association Report No. 3, …

This paper presents methods for determining the uncertainty of both differential and linear metering stations. It takes into account the type of meter, number of meters in parallel, type of secondary instruments, and the determination of physical properties. The paper then relates this information to potential influence on system balance
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.
