GSM/GPRS modem beyond is an intelligent modem for data transfer between an electronic energy meter and a central station over the GSM/GPRS communication network. Working in conjunction with base computer software (BCS) it provides a cost-effective solution for automatic meter reading (AMR). The modem can be programmed to automatically transmit SMS messages to the central station when certain metering events are detected. This extends the role of Intelligent GSM/GPRS modem beyond traditional remote meter reading and into the realm of system integrity monitoring and surveillance.
Application:- Ÿ GSM/GPRS-based remote meter reading (RMR) systems Ÿ Outstation modem, connected at the meter end Ÿ HV or LV metering installations
Benefits:- Ÿ Maximum operational flexibility: it can be used with any type of electronic meter Ÿ Increased productivity through collection of data via AMR Ÿ Minimal installation cost Ÿ Reduced logistical costs: NET METER works on single-phase or three-phase supplies Ÿ Notification of metering events through automatic SMS messages
