Split Type STS Prepaid Gas Meter with AMR/AMI function can realize prepayment function and remote semi-automatic/automatic meter data collection through integrated LoRa RF wireless Comm. Module inside. For Prepaid Function, it complies with International STS Standard IEC 62055-41,51 and gets the STS certification. Customers can purchase gas through multiple methods (Vending Points, Agency, Customer Self-service, etc.), and obtain a 20 digit recharge token. By inputting the recharge token through Customer Interface Unit (CIU), the Gas Meter will be recharged successfully.
AMR Functions
Meter Installation Location (GIS) info. Collection
Meter Reading Task Download from LAPIS Server
Meter reading path optimization
Automatic Meter Data Collection and upload
Remote Meter Valve Control
AMI Functions
Automatic Meter Data Upload
like Hourly/Monthly Consumption Data Record, Battery, Voltage, Meter Alarm Event etc.
Automatic Real Time Clock (RTC) Calibration
Real Time Communication, Remotely Control Valve Open/Close
Massive Data Storage
10 years' Hourly/Monthly Consumption Data Record
Meter Event Record during whole meters' lifespan, such as meter re-start, valve operation failure, magnetic interference, etc.
Anti-magnetic interference
If external magnetic interference happens, the meter shall close the valve and record this event with exact time and event type.
Low Battery Detection & Warning
2 Levels of Low Battery Warning
Data auto-save & Valve Close when battery low
