TH18874U - A system for measuring gas usage and calculating payment amounts for gas sales. - Google Patents

Abstract

This invention relates to a system for measuring gas consumption and calculating payment amounts for gas purchases and sales. It comprises key components: flow rate, pressure, and outlet gas temperature sensors. The measured values are transmitted to an Electronic Volume Corrector (EVC) for calculation of gas consumption. This data is then sent to a Remote Terminal Unit (RTU), which transmits it via a Narrowband Internet of Things (NB-IoT) network to a server for processing, recording, and disseminating the information to a display unit. This display could be via a website, an application notification, or an automated billing system for generating invoices. Furthermore, the gas consumption measurement and payment system includes safety devices such as shut-off valves and gas detectors.
