Smart and reliable AMR

ECD 210 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 ECD 210 beyond traditional remote meter reading and into the realm of system integrity monitoring and surveillance.
