They are not used to measure gas flow. Meter of choice for custody transfer. In , the American Gas Association (AGA) approved the use of ultrasonic flowmeters for custody transfer applications. Since that time, suppliers have researched multipath meters and brought out new products. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): [Ref 1] in June It is a recommended practice for using ultrasonic meters (USMs) in fiscal (custody) measurement applications. This paper reviews some of history behind the development of AGA Report No. 9 (often referred to as AGA 9), key contents and includes information on meter performance requirements, .
The ultrasonic gas flow meter max is a multipath ultrasonic gas flow meter utilizing the most accurate acoustic path configuration available to the market. Combining the best out of two worlds to maintain the lowest uncertainty with high robustness to meet the individual operational demands. The AGA published the recommended practice, Report No. 9 (Measurement of Gas by Multipath Ultrasonic Meters), in June At that time, there were three manufacturers selling ultrasonic flow meters for natural gas pipeline applications, and sales rose sharply. The technology had finally become a commercial success on a broad scale.
Book January with 54 prover and a multipath ultrasonic gas flow meter (USM). to provide increased insight into the potentials and limitations of crude oil measurement using. Ultrasonic meters excel in measuring the flow of natural gas. They are widely used for custody transfer of natural gas on pipeline transmission lines, where the pipe sizes can get quite large. The AGA-9 Report approves them for custody transfer of natural gas. Multipath meters .

AGA Report No. 9, Measurement of Gas by Multipath Ultrasonic Meters () Paperback – January 1, Manufacturer: American Gas Association. : AGA XQ AGA Report No. 9 - Measurement of Gas by Multipath Ultrasonic Meters (3rd edition, ): Everything Else.
multipath. ultrasonic. transit-time. flow meters that are used for the measurement of natural gas. A multipath meter is defined as one with at least two independent acoustic paths used to measure transit time difference of sound traveling upstream and downstream at an angle to the gas flow.
Today most users require a minimum of 3 acoustic pathsFile Size: KB. buy nbr measurement of gas by multipath ultrasonic meters from sai global.
Introduction Scope: Developed for multipath ultrasonic transit time flow meter. Principle of measurement. The meter measured gas flowrate by measuring transit times of highfrequency sound pulses. The Accuracy of USM depends on several factor, such as: Precise geometry of the meter Measurement of gas by multipath ultrasonic meters book and ultrasonic transducer location.
This report is for multipath ultrasonic transit-time flow meters used for the measurement of natural gas. It may be used for the measurement of other gases in consultation with the meter manufacturer and a competent professional.
Multipath ultrasonic meters have at least two independent pairs of measuring transducers (acoustic paths). Measurement of Gas by Multipath Ultrasonic Meters, 2nd edition in April and ISOMeasurement of fluid flow in closed conduits - Ultrasonic meters for gas, Part 1: Meters for custody transfer and allocation measurement in has greatly accelerated the installation of ultrasonic flow meters worldwide.
Today virtually. The American Gas Association published Report No. 9, Measurement of Gas by Multipath Ultrasonic Meters 2. Edition [Ref 1] in April Report 9 details recommended practice for using multipath gas ultrasonic meters (USMs) in fiscal (custody) measurement applications.
This paper reviews some of history behind the development of AGA Report. AGA Report No. 9, Measurement of Gas by Multipath Ultrasonic Meters () This report is a performance based specification for multipath ultrasonic meters for gas flow measurement.
It replaces the previous version that came out in June and reprinted in June Extremely accurate and reliable multipath ultrasonic metering systems have emerged as the measurement technology of choice for large volume gas transfer. Pushed by continuously improving signal processing technology and pulled by increasing customer requirements, multipath instruments provide state of the art gas flow measurement.

The new Daniel 8-path ultrasonic flow meter crafted, developed, and designed by Emerson, offers the highest accuracy and best in class performance coupled with the same high functionality required by sophisticated fiscal measurement users.
The combines the power of two interlocked 4-path British Gas design meters in one flow meter body. The second set of chords is the mirror image of the first, which allows the meter.
In the multipath ultrasonic gas flow-meter, the analysis of each path of ultrasound needs its own reference wave. In case study, a six-path ultrasonic gas flow-meter has been designed and tested with air flow through the pipeline.
This paper gives an introduction to the practical application of ultrasonic gas flow meters. A general outline of the theory and methods applied using multipath flow meters. The multi-path type meter provides state of the art gas flow measurements and its accuracy and reliability satisfy the requirements for custody transfer.
Title: Multipath ultrasonic flow meter for gas measurement The gas industry has long been looking for new and accurate methods for measuring large volumes of gas at high pressures.
Orifice metering is the most common method, but one major drawback is its rangeability. An important feature of ultrasonic flow meters - UFM is dealt by the publication of AGA report no.
