It not only retains the accurate metering function of the diaphragm gas meter, but also achieves a range of advanced features, including regular reporting of gas consumption data (automatic meter reading), wireless remote recharge, IC card prepayment, remote valve control, remote price adjustment, automatic fault reporting, and gas usage recording.
Safe, reliable, convenient and practical, this product provides effective measures for gas operation departments to implement scientific management. It is a high-tech mechanics product that enables gas companies to effectively improve their management capabilities.
Product Feature
· IoT Technology: Adopts NB-IoT (Narrowband Internet of Things) narrowband IoT communication technology for data transmission, featuring wide coverage, massive connectivity, and low power consumption.
· High-Security Design: Utilizes NB-IoT modules and surface-mounted SIM cards, with data transmitted via operators' public networks, ensuring safety and reliability.
· Scan-to-Pay: Supports scan-to-pay functionality, including WeChat Scan, Alipay Scan, and other mainstream scanning methods.
· Data Upload: Enables customizable cycle-based data reporting, as well as button-triggered and power-on data reporting functions.
· Remote Valve Control: Allows remote valve operation; in cases of emergencies or customers with malicious arrears, the valve can be remotely shut off.
· Payment & Recharge: Supports self-service payment and recharge through mobile apps or WeChat Official Accounts.
· Payment & Recharge: Supports self-service payment and recharge through mobile apps or WeChat Official Accounts.
· Valve Shutdown When Not in Use: Features a two-level valve shutdown function that activates if no gas is used for n days, ensuring safe gas usage.
· Fault Reporting: In the event of abnormalities such as magnetic interference, valve malfunctions, abnormal high flow, or low battery, the valve will automatically shut down, and fault information will be proactively reported to the management system for streamlined management.
