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 both gas and liquids measurement. With a commitment to excellence, ASGMT now offers an extensive curriculum comprising over 115 lecture classes, complemented by 48 Hands-On Product Training sessions led by industry experts.
This paper discusses advanced diagnostic features of ultrasonic gas flow meters used for measurement of natural gas which are generally used to assess dynamic meter operation and performance. The basic diagnostic features of most gas ultrasonic flow meters were covered in the companion paper “Ultrasonic Meter Diagnostics – Basics” which covered diagnostics that relate to …
This paper discusses fundamental principles of ultrasonic gas flow meters used for measurement of natural gas and the available basic diagnostic capability to assess meter operation and performance. The basic requirements for obtaining good meter performance, when installed in the field, will be reviewed. Most of this information can be generalized to other manufacturer’s transit …
There are many in our industry who would consider the advancement of the ultrasonic meter to be the greatest improvement in gas measurement in the past twenty years. It’s my opinion that the immense improvement in gas measurement is not so much the ultrasonic meter itself. Instead, I believe it is the meter’s ability to …
Training office personnel offers many new challenges for the back office measurement supervisor. As the industry changes, the office supervisor is tasked with the responsibility of training office personnel on many aspects of the industry. New methods of measurement, along with advances in communication and business practices need to be included in training office personnel.
Orifice plate meters are popular for being relatively simple, reliable and inexpensive. Their principles of operation are relatively easily understood. However, traditionally there has been no orifice meter self diagnostic capabilities. In 2008 & 2009 a generic Differential Pressure (DP) meter self diagnostic methodology [1,2] was proposed. In this paper these diagnostic principles are applied …
The National Electrical Code (NEC) defines hazardous locations as those areas “where fire or explosion hazards may exist due to flammable gases or vapors, flammable liquids, combustible dust, or ignitable fibers or flyings.” A substantial part of the NEC is devoted to the discussion of hazardous locations. That’s because electrical equipment can become a source …

With the recent release of the Green House Gas Regulations, the increased visibility of flaring natural gas and increased awareness of royalty owners, the ability to accurately measure and account for the amount of product flared from a facility has become increasingly important to regulators, royalty owners and operators. In the past, flare gas was …
Electricity has been used for more than a century as a source of motive power and means of conveying information. While the two uses may seem very different at first glance, they are governed by the same basic principles. Technicians in the modern oil and gas field can find a cursory understanding of these basics …
For many years now, flow computers have been implemented in gas measurement systems to utilize technology, to improve measurement accuracy, provide far more efficient data acquisition, and provide better control resources for remote interface through telemetry. As the meter’s functionality has increased, the meter technician has had to become more diverse in his or her …
Pressure calibration is as important today as it has been for a very long time, but the way calibration is done and the equipment used to do it has changed drastically. In the past it was a standard practice to use a primary standard for pressure calibration. That standard was normally a dead weight tester …
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.
