STG16-S Split Keypad Prepaid Gas Meter

Split-type prepaid gas metering system composed of a meter unit and a separate customer interface unit (CIU), designed for controlled gas distribution and secure billing in residential and utility environments.

The system supports STS-compliant prepaid functionality, enabling token-based recharge, flexible tariff configuration and controlled consumption management. An integrated valve allows automatic control of gas supply based on credit status and system conditions.

With LoRa-RF communication (optional PLC/GPRS), the meter supports integration into AMI systems for remote monitoring, data collection and centralized management. The split design improves installation flexibility and user accessibility.

Built with IP67 protection and robust housing (aluminum or steel case), the unit is designed for stable operation in demanding environments. Features such as magnetic tamper protection, event logging and low-credit alerts enhance system security and operational reliability.

Designed for long-term deployment, the meter supports up to 6 years of battery life and is suitable for residential gas distribution systems requiring prepaid control and infrastructure-level management.

Compliant with ISO9001, ISO14001 and STS standards, supporting deployment in regulated and utility-managed environments.
