Two Way Communication Single Phase Watt Hour Meter Polycarbonate Build - In GPRS
The CA168-G is our new system component for the Calin's AMI AMR solution, which integrates four functions in one device: an extremely flexible advanced electricity meter, a multi-energy data collector, a remote two-way communication node, and a powerful interface to enable end user interaction.
The CA168-G meter has been designed to provide you with the maximum flexibility in functionality and in infrastructure needs. Covering a wide range of uses, you will be able to adapt your meter solution according to future needs.
The meter communication interfaces are based on open standards. This allows you to combine third party applications in your advanced meter infrastructure.We aim to provide you with the best cost-effective products instead of expensive high-tech fancy format. Our design principles provide you with a high quality system component which is easy to install and requires minimum maintenance across its long life time.
