Abstract
An electronic utility gas meter using MEMS thermal time-of-flight flow sensor to meter gas custody transfer mass flowrate and an additional MEMS gas sensor to measure the combustion gas composition for the correlations to the acquisition of gas high heat value simultaneously is disclosed in the present invention. The meter is designed for the applications in the city utility gas consumption in compliance with the current tariff while metering the true thermal value of the delivered gases for future upgrades. Data safety, remote data communication, and other features with state-of-the-art electronics are also included in the design.
