Exploring a 'Total Energy Concept' (TEC) for Natural Gas Metering

摘要

In this paper, we consider the theory supporting a Total Energy Measurement Concept (TEMC, abbreviated herein as "TEC") for Natural Gas metering systems deploying both Turbine and Ultrasonic flow meters in-series ("twin set"). The 'first stage' laboratory results of an installed system is discussed based on general principles, current and working standards/recommendations, and related to laboratory results that were recorded during actual calibrations. Data is shown for normal calibration conditions. The paper provides an insight into theoretical and practical engineering resulting in experiential learning for a new 'Total Energy Concept' (TEC) deploying a Turbine meter, an Ultrasonic flow meter, a Gas Chromatograph, and a TEC dedicated supervisory system.
