R eduction of nonrevenue water use is currently a common goal for most water distribution systems. Nonrevenue water consists of water lost either through real losses (e.g., underground leakage) or through apparent losses (e.g., metering inaccuracies and unauthorized use). Reducing the apparent losses caused by meter inaccuracies at low flows can result in substantial short-term increases in uti...

A new analytical equation for prediction of temperature profile of a buried gas pipeline is developed. Utility of this equation is illustrated by its application to corresponding states principle. The resulting equation is tested through prediction of the actual Schorre data. It is shown that the new equation can predict temperature profile more accurately than the others without using any char...

Smart meters report power usage at 15 minute intervals and, compared to monthly power bills, provide the users with a much finer resolution time series of energy usage. However, apart from identifying times of peak energy usage, these smart meters provide little actionable data for the user in terms of reducing their power costs. Our research involves the development of an intelligent metering ...

The Venturi meter is a straightforward pipeline device used for the metering of gas and liquids. This article presents a brief summary of the creation and characterisation of the modern Venturi meter, including the historic development of public domain algorithms to derive two phase (gas and liquid) flow rates from differential pressure measurements. The use of Venturi meters in multiphase oil ...

The classical solutions for collecting data from energy meters, based on human readings, tend to be replaced by modern solutions. Automatic Meter Reading (AMR) is such a modern solution. It means to automatically collect data from different kinds of meters. In this way consumption of water, gas and energy can be remotely measured. An Advanced Metering Infrastructure (AMI) is an AMR infrastructu...
