UNACCOUNTED-FOR GAS STUDY IN GAS DISTRIBUTION NETWORKS In the Gas Distribution business Unaccounted Gas is referred to by various names or terms such as: Lost and Unaccounted-For, LUG, L&U, and UAF. In simplest terms, Unaccounted Gas is the result of the formula “gas receipts minus gas deliveries”. For the Measurement Group the process amounts to a “gas inventory reconciliation” based on the…

ULTRASONIC METERS FOR RESIDENTIAL AND COMMERCIAL APPLICATIONS An ultrasonic meter falls into the classification of inferential meters. Unlike positive displacement meters that capture volume to totalize volume, inferential meters measure flowing gas velocity to totalize volume. Orifice meters use pressure drop to measure velocity to infer volume and turbine meters use the speed of the rotor to measure velocity to infer volume,…

FIELD INSPECTION AND CALIBRATION OF VOLUME CORRECTING DEVICES Timely, diligent field testing and calibration of gas volume recording and correcting instruments ensure that measurement information fairly represents actual volumes. The instruments save a company capital and operating costs because they can record or integrate volumes at pressures and temperature above the normal pressure base conditions specified in contracts for volume calculation. This allows…

WIRELESS METER READING There was once a time when you could get a car in any color…as long as it was black. They had frames, running boards and 15 horsepower engines. Who could ever need more? Just like the auto industry has adapted from this original approach to meet the demands of consumers, regulators and shareholders, the gas…

PRODUCTION EQUIPMENT EFFECTS ON ORIFICE MEASUREMENT The condition of gas as it presents itself in the pipeline is often not ideal for accurate measurement, by an orifice flow meter. It is the requirement of the American Gas Association (AGA) that the natural gas be in a single phase and with a swirl-free fully developed profile as it passes across the orifice…
