Professional Lora Smart Three Phase Four Wire Energy Meter With
DLMS / COSEM Protocol
Description:
The meter is an IEC standards compliant three phase four wire smart
electric meter. It is completed in BS footprint housing and
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.

Function:
The meter is intended for communicating with a head-end central
station server (HES) 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. It is built-in with a clock
countsas incrementing second index. This index is synchronized with
the real time in HES at preset interval period, offering the
utility utmost flexibility of tariff calculation and system
management. 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.
