This paper is intended to discuss various methods used to collect Electronic Gas Measurement (EGM) data. There are quite a few options on the market today when it comes to remote measurement data collection in the Natural Gas Industry. Due to advancements in technology, we have seen changes in most all the options available making …

Methods of Gathering Electronic Gas Measurement (EGM) Data Read More »

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 …

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 …

This paper presents methods for determining the uncertainty of both differential and positive metering stations. It takes into account the type of meter, number of meters in parallel, type of secondary instruments, and the determination of physical properties. The paper then relates this information to potential influence on system balance.

Just when you thought you knew everything there was to know about Turbine meter measurement, wham, out comes a revised AGA 7 standard. Now those basic principles are all still valid but maybe those operating practices we have built into our operating procedures need a little review. Rather than proceed as generations have done before …

This paper explains the general working principle of gas turbine meters and the common causes for turbine metering errors. Field observations and laboratory test examples are presented in this paper to demonstrate these phenomena. The author also suggests methods to optimize the measurement performance of turbine meter installations.

Some major problems and unique solutions will be addressed with gas measurement on offshore platforms in the Gulf of Mexico. This presentation will show the major roll safety, transportation, and weather play in the technician’s ability to verify the accuracy of the gas measurement facility. Proper operation, design, and installation will ensure accurate measurement.

The condition of gas as it presents itself in the pipeline is often not ideal for accurate measurement, by an orifice flow meter. It is the requirement of the American Gas Association (AGA) that the natural gas be in a single phase and with a swirl-free fully developed profile as it passes across the orifice …

This presentation addresses problems associated with moisture and corrosion caused by high relative humidity and airborne contaminants. By controlling moisture and corrosion long-term, many problems associated with sensitive field electronics can be avoided.

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 …
