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 measuring fluids in both gas and liquid states. With a commitment to excellence, ASGMT now offers an extensive curriculum comprising over 120 lecture classes, complemented by 54 Hands-On Product Training sessions led by industry experts, and sessions providing a brief overview of new products.
What Are They and Why Are They Needed What: A stand-alone device that opens and recloses at a pre-selected pressure, containing an orifice sized to flow a required capacity to prevent / avoid overpressure. Why: All natural gas equipment (pipelines, pressure vessels, air-cooled heat exchangers, compressor cylinders, odorant tanks, instrument control lines, valves, underground storage, …
In the gas industry, there are two basic types of regulators used for both pressure reducing and back pressure (relief) control. The two types are: Self Operated Regulators (Sometimes referred to as spring loaded regulators) Pilot Operated Regulators (Loading and Unloading style pilot regulators) This paper will discuss the basic principle of Self …
The history of orifice metering began in the early 1900’s. The first test data was done by the U.S. Geological Survey and in 1913 the first “Handbook of Natural Gas” was published. So, as you can tell, orifice metering has been around for over 100 years and in that time, much has been learned and …
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 worldwide 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. Often users try to employ the same measurement practices that …

This paper discusses fundamental principles of ultrasonic gas flow meters used for measurement of natural gas. A review of an ultrasonic meter’s operation and the equations used to determine actual volumetric flow is presented. The ultrasonic flow meter’s diagnostic capability will also be briefly presented. Further, diagnostic data, in conjunction with gas composition, pressure and …

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. Orifice, ultrasonic and turbine meters are the three main inferential class meters used for large …
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. When the unit of purchase is the energy content (BTU) we achieve …
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. Discussed is the historical transition from volumetric measurement to total gas energy including some …
Electronic flow measurement as applied to the natural gas industry has advanced considerably over the last 30 years. Applications to address Upstream, Midstream and Downstream gas measurement technologies have become more complex. Over time it has become necessary to understand the fundaments that make up this ever changing environment. This paper will discuss the important …
