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.
INTRODUCTION 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.
INTRODUCTION 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 …

INTRODUCTION Transfer proving was initially developed to provide an easier and more accurate field meter proving method. Because of the capacity capabilities of transfer provers (2000 CFH to 80,000 CFH) transfer provers are utilized in meter shops where bell prover capacity is limited and allow for shop testing of the larger capacity meters.
INTRODUCTION The natural gas industry relies very heavily on sensitive electronic equipment utilized in the production, gathering, transportation, and distribution phases. There is an increasing reliance on the use of electronics for performing important tasks relating to measurement, control, and safety. Coupled with increased reliance is the demand by users for increased reliability.
Introduction This paper will provide you with a fundamental understanding of the operating principles of currently available pipeline leak detection technologies. To start with we’ll have a look at the topics to be covered: • Historical development of pipelines • Why they are monitored for leaks • The requirements and regulations placed on leak detection …

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 …

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, …
INTRODUCTION 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 pressure- base conditions specified In contracts for volume calculation. This …

Meter inspections, configuration changes, calibration verification, troubleshooting, and gas sampling generate important subsets of measurement data. Automated computer systems capture, process, store, and report this data better than manual, paper-based systems minimizing effort, time, resources, and error for field and office workers
Experience is the best teacher. We’ve all heard that saying, but, what if there aren’ t any experienced personnel left to hire? After years of downsizing, mergers, and attrition, the industry finds itself in a shortage of good trained personne1. The only way to overcome this problem is to provide the new employee with comprehensive …
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.
