Abstract
An electronic utility gas meter using MEMS thermal mass flow sensor to measure gas custody transfer data in city gas metering application is disclosed in the present invention. The meter is designed to have its mechanical connectors identical to those of the current diaphragm gas meters while the insertion metrology unit guided channel is placed coaxially in the main flow channel inside the meter body with gas flow conditioning apparatus. The mechanical installation of the electronic utility gas meter then can be fully compatible with the current mechanical utility gas meters, which allows a seamless replacement. The electronic utility gas meter provides gas metrology that significantly improves the accuracy of the city gas metering, and provides additional benefits for data safety, enhanced gas chemical safety, billing alternatives and full data management either locally or remotely.
