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.
It is strictly prohibited to install it in bedrooms, bathrooms, hazardous and flammable material storage areas, and places similar to the above situations.
The installation of gas meters should meet the requirements of meter reading, maintenance, upkeep, and safe use.
