STE38-G GPRS
Three Phase DLMS Smart Electricity Meter
The meter works with a plug-in module for DLMS/COSEM compliant data collection and network communications. This modular design enables utility to select from PLC/RF/GPRS/3G and 4G LTE cellular data networks according to local conditions at low cost. Upgrade and maintenance will also become cost-effective by replacing the modules only instead of the entire meter.
