DLMS Lorawan Smart Meter Three Phase Four Wire Meter for AMR/AMI
System
The meter is an IEC standards compliant three phase four wire smart
electric meter. It integrated with large innovative capabilities,
such as powerful e-metering, multienergy data collection, remote
and local communication. This new generation of metering device has
been developed as a core component of the Radarking’s smart
metering solution to optimize daily utility processes.
The meter is intended for communicating with a head-end central
station server (Paas) through GSM / GPRS / Ethernet connectivity
for smart metering interactions on real time basis. It is ideal for
a broad range of commercial and inustrial environments. The meter
measures active and reactive energy and its terminal block provides
both direct and CT/VT connection. This flexibiity futhermore
enables the utility to apply different contractual control to each
of the customer with no need to visit customer's premises or adding
accessories from time to time.
The connectivity of GSM GPRS enables the utility and service
providers to have a real-time monitoring and control on the load in
the grid and improve their managing efficiency at peak hours. The
meter records maximum demand and load profiling data at programmed
intervals and provides valuable instantaneous value for P, V, A, PF
for the utility and customer as well for them to budget their usage
and manage the load.
