This paper outlines the operating principles and application of ultrasonic gas flow metering for custody transfer. Basic principles and underlying equations are discussed, as are considerations for applying ultrasonic flow meter technology to station design, installation, and operation. These applications are illustrated based on operating experience with the SICK ultrasonic flow meter, however...

The high incidence of electricity theft, meter tampering, bypassing, reading errors, and defective aged meters, among others, increases utility losses, especially non-technical losses (NTL). A in Ghana piloted a loss reduction program 2019 to replace postpaid meters with anti-tamper, anti-fraud, anti-theft smart prepaid meters. By using customer-level residential billing panel data from 2018 ob...

Mechanically-driven syringes used to test peak expiratory flow (PEF) meters must produce the American Thoracic Society (ATS) standard waveforms with PEF accuracy of 2%. However, gas compression within the syringe could result in significant PEF inaccuracy when testing high resistance meters. The gas compression artefact was investigated in a mechanical syringe (PWG; MH Custom Design & Mfg L.C.,...

Over the past years, smart meters have been widely deployed in many countries. These devices replace conventional electrical meters and are able to provide measurements for time intervals of typically less than one hour and can send these to the utility. This technology provides utilities a large amount of data and the opportunity to use this data to improve the way they run the grid. We want t...

This paper discusses fundamental issues relative to ultrasonic gas flow meters used for measurement of natural gas. A basic review of an ultrasonic meter’s operation is presented to understand the typical operation of today’s Ultrasonic Gas Flow Meter (USM). The USM’s diagnostic data, in conjunction with gas composition, pressure and temperature, will be reviewed to show how this technology pro...

This paper discusses fundamental principles of ultrasonic gas flow meters used for measurement of natural gas. A review of an ultrasonic meter’s operation and the equations used to determine actual volumetric flow is presented. The ultrasonic flow meter’s diagnostic capability will also be briefly presented. Further, diagnostic data, in conjunction with gas composition, pressure and temperature...

A considerable contribution to the worlds total GHG emission originates from gas flaring: According to a World Bank estimation an amount of around 150 billion cubic meters of natural gas is flared around the world annually, contaminating the environment with 400 million tons of CO2. This is equivalent to around 25 % of the United States’ gas consumption, or 30 % of gas consumption in the Europe...

Mass flow measurement is the basis of most technoeconomic formulations in the chemical industry. This calls for reliable and accurate detection of mass flow. Flow measurement laboratory experiments were conducted using various instruments. These consisted of orifice plates, various sized rotameters, wet gas meter and soap bubble meter. This work was aimed at evaluating appropriate operating con...

A utility’s meter data is a valuable asset that can be daunting to leverage. Consider that one household or premise can produce over 35,000 rows of information, consisting of over 8 MB of data per year. Thirty thousand meters collecting fifteen-minute-interval data with forty variables equates to 1.2 billion rows of data. Using SAS® Visual Analytics, we provide examples of leveraging smart mete...
