Scope of use: Suitable for measuring natural gas, liquefied petroleum gas, biogas, coal to gas and other gases.
Functional features:
1) Low static power consumption and long battery life;
2) Information such as insufficient remaining gas, low battery voltage, and valve status is displayed in Chinese, with an intuitive interface;
3) Multiple encryption verification for data access, secure and reliable;
4) Automatic detection and troubleshooting of sensor faults;
5) Abnormal information recording and gas meter usage data feedback function;
6) The maximum allowable gas storage capacity can be set to avoid users hoarding gas in large quantities and reduce losses caused by gas price fluctuations in the gas operating department;
7) Overdraft gas volume and alarm value can be set by users;
8) The maximum idle days of the gas meter can be set;
9) The face mask and module have undergone moisture-proof and oil fume proof treatment;
10) The management software adopts a modular design, with a user-friendly interface, intuitive and easy to understand operation;
11) It can achieve remote control of gas meters, including data reading, parameter adjustment, and switch control.
It is recommended to install in non combustible structures with good indoor ventilation.
