The American School of Gas Measurement Technology (ASGMT) has never turned its back on change since its founding in 1966. Instead, it has consistently embraced progress and pursued new ways to strengthen our industry and support the development of our students. This year is no exception. After 25 years at our previous venue, ASGMT has proudly relocated to The Woodlands Waterway Marriott Hotel and Conference Center. This move underscores our continued commitment to remaining at the forefront of industry evolution and delivering the highest‑quality experience for our students and the broader measurement community.
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 …

Gas measurement in the U.S. and around the world is dominated by diaphragm, rotary, turbine, and orifice meters. Each serves a different segment of the gas industry and each has its own set of advantages and disadvantages. These four main types of meters can be broken into two distinct categories: positive displacement, and inferential. Diaphragm …
Natural gas measurement today is accomplished through the use of two different classifications of gas meters. The first consists of inferential type meters, including, orifice, ultra-sonic and turbine meters, and the second is the positive displacement meters, which consist of diaphragm and rotary displacement meters. The inferential type meters are so-called because rather than measuring …

The first gas company in the U.S., The Gas Light Company of Baltimore, Maryland, founded in 1816, struggled for years with financial and technical problems while operating on a “flat rate” basis. Its growth was slow with the charge for gas service beyond the pocketbook of the majority. By comparison, the New York Gas Light …

What Are They and Why Are They Needed What: A stand-alone device that opens and re-closes 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 Distribution business Unaccounted Gas is referred to by various names or terms such as: Lost and Unaccounted-For, LUG, L&U, and UAF. In simplest terms, Unaccounted Gas is the result of the formula “gas receipts minus gas deliveries”. For the Measurement Group the process amounts to a “gas inventory reconciliation” based on the …

An ultrasonic meter falls into the classification of inferential meters. Unlike positive displacement meters that capture volume to totalize volume, inferential meters measure flowing gas velocity to totalize volume. Orifice meters use pressure drop to measure velocity to infer volume and turbine meters use the speed of the rotor to measure velocity to infer volume, …

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 capital and operating costs because they can record or integrate volumes at pressures and temperature above the normal pressure base conditions specified in contracts for volume calculation. This allows …

There was once a time when you could get a car in any color…as long as it was black. They had frames, running boards and 15 horsepower engines. Who could ever need more? Just like the auto industry has adapted from this original approach to meet the demands of consumers, regulators and shareholders, the gas …
SCADA systems provide are combinations of field devices, communications infrastructure and software integrated into a system that provides for safe, reliable, and effective operation of remote facilities. Producers, gatherers, midstream operators and pipelines use SCADA system for operations. In addition, SCADA gathers data used by advanced applications such as measurement accounting. SCADA is key for …
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.
