Prometer 100, series of next generation energy meter designed
for power transfer points requiring precise measurements and
revenue transactions. Flexible and modular communications
ensure integration with AMR / AMI / SCADA systems and
upgrade to future sub-station automation systems. 4 quadrant
energy measurement allows monitoring of generation,
transmission and distribution loads.

Prometer 100
System architecture
The Prometer 100 offers various communication modules such as RS232 with output to power up terminal modem, RS485 for multi-
drop connectivity and Ethernet for integrating into communication bus. The communication modules can be hot plugged in field
and locally or remotely configured for ids, IP addresses. Dual socket support on Ethernet allows for simultaneous communication
over MODBUS and DLMS through different clients. All communication ports can simultaneously transfer data at high speeds.
