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, …
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 …

Many (likely most) gas pipeline companies struggle with lostand- unaccountcd-for-gas (L&U) and it can be a significant cost to their bottom line as shown below. As shown in this inset, by reducing L&U from 0.6 percent to ,25 percent, a typical company with a 2 BCF daily throughput could save almost S18 million annually based …

Over 300 people died in an explosion on March 18, 1937 in a New London, Texas public school building. The natural gas that was being delivered to the school building was not odorized. At that time the natural gas was odorless, and there wasnt a law on record to mandate Odorization. As a direct result …
With the increased use of Natural Gas as a fuel, and higher natural gas prices buyers and sellers of natural gas are seriously looking at ways to improve their natural gas measurement and reduce the error in natural gas measurement. A 6 Turbine or Ultrasonic meter operating at 1,000 Psi will move 100 MMSCF/Day. An …
Meter station piping installation configuration is one of a number of effects that may adversely affect meter accuracy. Some piping configurations can distort the flow stream and produce flow measurement bias errors (i.e., offsets in the meter output) of up to several percent of reading. Valves, elbows, or tees placed upstream of a flow meter …
Natural gas sampling is performed for a variety of reasons. Sampling is performed to determine total gas composition, hydrocarbon dew point, specific gravity, and most importantly, the value of the gas. Three techniques are normally used to obtain gas samples continuous composite sampling, continuous online sampling, or spot sampling. This paper will discuss the various …
What is a standard? Why are standards important? Merriam-Webster dictionary defines standard as: 1) a conspicuous object (as a banner) formerly carried at the top of a pole and used to mark a rallying point especially in battle or to serve as an emblem 2) something established by authority, custom, or general consent as a …
An Overview of Industry Standards Related to Natural Gas Measurement Read More »
Measuring natural gas is both a science and an art. Guidelines and industry practices explain how to accurately measure natural gas. The art comes in trying to minimize errors and prevent measurement problems. However, sometime its easier to explain how not to measure gas when reviewing measurement errors. Measurement errors can be caused through poor …
As the energy business has evolved, so too have the measurement and communications needs associated with the ever-changing operational, informational, business and regulatory requirements. Energy quantities now realize dynamic valuations that can experience large variances within very short time periods. Skill requirements of personnel are constantly changing as technologies develop. Energy goals must be accomplished …
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.
