Calculation Of Natural Gas Liquid Quantities

Author: Keith FryDownload File

There is no substitute for well maintained, properly installed, and properly performing measurement equipment. Provisions for measurement equipment installation, operation, and maintenance deliver the raw data required for those dealing with natural gas liquids (NGLs) to transact business. Then, this raw data can be adjusted or converted to values suitable for transactions to take place […]

Clamp-on Ultrasonic Flow Meter Application And Performance

Author: WilliamE. Frasier (retired) & Joseph NettletonDownload File

This paper is directed to ultrasonic natural gas meters using transit time across the gas pipe as the measurement variable. Custody transfer meters using sensors wetted with gas are the more familiar meter format. Clamp-on meters are quite similar.

Considerations For Liquid Measurement In Production Applications

Author: Joey RaskieDownload File

With the proliferation of horizontal drilling allowing access to tight oil formations, liquid production in the U.S. has significantly increased over recent years. Consequently, there is renewed interest in accurate measurements for both custody transfer and allocation purposes. Advances in measurement automation have yielded operators’ savings in the millions of dollars annually. Over the last […]

Continuous Monitoring Of Ultrasonic Meters

Author: Randy MillerDownload File

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 […]

Coping With Changing Flow Requirements At Existing Metering Stations

Author: James M. DoyleDownload File

In today’s competitive gas market, utility companies must meet aggressive market strategies or suffer the consequences. All industries have cash registers, and gas distribution is no exception. Our measuring stations are our cash register. The problem is, these stations were designed 10, 20, 30 or even 50 years ago, and are now performing tasks they […]

Coriolis Mass Flow Meters For Gas And Liquid Measurement

Author: Michael KeiltyDownload File

A mass flowmeter is a system that provides a measurement of fluid flow in units of mass; pounds, tons. The Coriolis flowmeter is a type of flowmeter which measures the mass of the fluid flow directly. Coriolis mass flowmeters were first introduced more than 30 years ago. Global acceptance has spread across all industries where […]

Differential Meters Other Than Orifice

Author: Kenneth Reed, IIIDownload File

Cone meters differ from other differential pressure type meters, such as orifice meters and Venturi meters, basically, by design only. They are all required to meet American Petroleum Institute (API) Manual of Petroleum Measurement Standards (MPMS), Chapter 22.2 (entitled “Testing Protocol for Differential Pressure Flow Meter Devices”) test criteria developed and published in 2005 and […]

Effects And Control Of Pulsation In Gas Measurement

Author: Edgar B. Bowles, Jr. & Christopher GrantDownload File

One of the most common measurement errors and the most difficult to identify in natural gas metering systems is that caused by pulsating flow. It is important to understand the effects that pulsations have on the common types of flow meters used in the gas industry so that potential error-producing mechanisms can be identified and […]

Effects Of Wet On Orifice Meters

Author: Josh Kinney & Richard StevenDownload File

Orifice plate meters are one of the most widely used technologies in industry for gas flow metering. This is due to their relative simplicity, the extensive publicly available data sets that led to several orifice plate meter standards [1, 2, 3, 4] and the fact that they are a relatively inexpensive method of gas metering. […]

Effects Of Flow Conditioning On Meter Accuracy And Repeatability

Author: Danny SawchukDownload File

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 […]
