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.
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. Measuring NGL by mass measurement techniques will properly address solution mixing effects because …

This document will provide the reader an understanding of what a prover is, the need for proving meters for accurate measurement uncertainty verification, the equipment deemed acceptable and available for use in the oil and liquefied gas market. It will also define the general terminology used in the industry, general operational aspects for verification devices, …

The first flow meter utilizing the Coriolis force to measure mass flow was patented in 1978. Today, hundreds of thousands of Coriolis meters are in service in the hydrocarbon industry to measure mass, volume, and density of a wide variety of fluids. The American Petroleum Institute published Chapter 5.6 entitled “Measurement of Liquid Hydrocarbons by …

This paper will discuss the role of the pycnometer in density meter calibrations. The primary objective will be to provide the necessary steps required to properly install, operate, and maintain the densitometer and pycnometer (pyc). Common issues encountered with pycnometers as well as densitometers are also discussed.
The word “Auditing” is often used to imply that activities related to a review of general business practices, and procedures for an asset or business unit, are under way. The objective of those activities is to assure compliance with corporate policies and procedures, industry and government standards, and sound management principles. Additional objectives may include …
Liquids measurement in the oil patch is suddenly getting a lot of attention. Some are dismayed at the low level of technology used to measure liquids. Today, custody transfer of 80 to 85% of onshore crude and condensate production is still documented by a hauler climbing to the top of the tank and strapping it. …
This paper discusses fundamental principles of ultrasonic gas flow meters used for measurement of natural gas and the available basic diagnostic capability to assess meter operation and performance. The basic requirements for obtaining good meter performance, when installed in the field, will be reviewed. Most of this information can be generalized to other manufacturer’s transit …
This paper discusses advanced diagnostic features of ultrasonic gas flow meters used for measurement of natural gas which are generally used to assess dynamic meter operation and performance. The basic diagnostic features of most gas ultrasonic flow meters were covered in the companion paper “Ultrasonic Meter Diagnostics – Basics” which covered diagnostics that relate to …
The primary method for custody transfer measurement has traditionally been orifice metering. While this method has been a good form of measurement, technology has driven the demand for a new, more effective form of fiscal measurement. Ultrasonic flowmeters have gained popularity in recent years and have become the standard for large volume custody transfer applications …
