The measurement of natural gas liquids (NGL) is similar in many respects to that of other hydrocarbon liquids but is markedly different in other aspects. The main difference in NGL measurement is the need to properly address the effects of solution mixing. Measuring NGL by mass measurement techniques will properly address solution mixing effects because …

This paper provides a fundamental overview of an NGL meter station design reviewing the nuances of configuring similar components in different ways. There are multiple considerations that influence the meter station design and all must be taken into account. Major considerations are: what product or products will be measured, what meter technology to utilize, and …

The purpose of this paper is to discuss in depth the systems we use as a standard to sample natural gas liquids, or NGL’s. Before we discuss the systems and methods used to sample these products, we must first clearly define what NGL’s are. NGL’s can be a combination of any fluid in liquid form …

Turbine meters have been used for the custody transfer of refined petroleum products and light crude oils for over 40 years. When correctly applied, they offer high accuracy and long service life over a wide range of products and operating conditions. Traditionally turbine metes were used for the measurement of low viscosity liquids and PD …

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 …

We say Advanced Wireless Data Radio Communication Systems Design Process not because this is a more in- depth and more technical process, but because the systems involved are complex in nature and must be carefully designed and programmed. If anything, what I want to do is teach you a more simplified approach and technique to …

Electronic gas measurement auditing or EFM auditing is a very important process in the natural gas industry. Within the last twenty years, the natural gas industry has changed from the dry flow chart recorder to the Electronic flow Computer(EFM) as the primary method of recording the measurement data for custody transfer. These flow computers are …

Measurement requires the highest level of ethical integrity in an industry that relies on ethical integrity at every level. A measurement professional is the provider of data to all the other professionals involved in the petroleum industry. If the measurement professional fails at their assigned duties, all the other branches of this industry make decisions …

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.
