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.

Fundamentals of Orifice Metering Introduction 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…

VERIFICATION / CALIBRATION OF DEVICES USED IN STATIC LIQUID MEASUREMENTS The purpose of verifying or calibrating liquid measurement devices is to ensure the accuracy of quantities being reported. With millions of dollars at stake, fractions of an inch or tenths of a degree Fahrenheit can make quite an impact to bottom line. At its most basic, the static (as opposed to dynamic, the use of…

FUNDAMENTAL PRINCIPLES OF DIAPHRAGM DISPLACEMENT METERS 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.

ULTRASONIC METERS FOR RESIDENTIAL AND COMMERCIAL APPLICATIONS 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…

FIELD TESTING BY TRANSFER PROVING 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.

PROTECTION OF NATURAL GAS MEASUREMENT EQUIPMENT AGAINST MOISTURE AND CORROSION 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.

Unaccounted-For Gas Study in Distribution Networks 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…

FUNDAMENTALS OF PRESSURE RELIEF VALVES IN NATURAL GAS INSTALLATION – OPERATION – MAINTENANCE 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,…
