The knowledge base from a field measurement technician to the measurement analyst is extremely demanding. Every field technician is tested in both knowledge and skills on a daily basis regarding:  Electronic controls to pneumatic controls  Communication system support  Multiple technical disciplines  Support of measurement equipment  Procedures that must be followed …

IMPROVING FLOW MEASUREMENTS WITH IMPROVED CALIBRATION AND DATA HANDLING PROCEDURES Read More »

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 …

In the discussion of ethics the first issue is always nomenclature. Sadly, this is often the topic that gets the least attention and frequently those involved in the conversation conduct deep insightful discourses in which there is virtually no understanding exchanged, although the participants will all agree that the quality of the rhetoric was outstanding.

In the gas industry a standard unit of measure is required. In the English system it is the standard cubic foot. In the metric, it is the standard cubic meter. This standard unit is the basis of all exchange in the gas industry. When the unit of purchase is the energy content (BTU) we achieve …

The Natural Gas and Oil industry is continually driven by cost cutting measures and the need to gain more operational efficiencies and visibility to regulatory requirements. This paper summarizes a solution in which wireless instruments integrate with other conventional equipment to offer a rapidly deployable advanced well optimization system.

The measurement of hydrocarbons has evolved significantly through the years, from both a technical and business application perspective. Developments and advances in technology have made the measurement of hydrocarbons more precise, efficient and available. Changes in the energy business environment have placed the measurement of hydrocarbons into a more significant role within organizational and industry …

A CURRENT PERSPECTIVE ON MEASUREMENT The Impact of Measurement in a Changing Business Environment Read More »

Flow conditioning is one of the most critical aspects dealing with any type of volumetric flow metering. Flow conditioning is the final buffer between the flow meter and the upstream piping layout and is responsible for eliminating swirl, restoring flow symmetry and generating a repeatable, fully developed velocity flow profile. Even though modern advancements have …

Fluid Flow Conditioning for meter accuracy and repeatability 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.

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 …

Ultrasonic Meter Diagnostics – Advanced – Overview of advanced diagnostic features of wetted-sensor ultrasonic flow meters Read More »

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 …
