NWE SRM
Description
Overview
NWE SRM is used to convert any Electronic Energy Meter into Smart Meter with a retrofit arrangement. It can read energy meters of different makes and models with proprietary or open domain protocols. NWE SRM has provision for load connect/disconnect and provision for connecting (RS232/optical) to communication port of the existing energy meter. It can be enabled with either RF based or GSM based communication module. GSM enabled SRMs can directly send the real-time meter data to HES over 2G/3G networks whereas RF enabled SRMs will communicate to the HES via GPRS enabled HHC/ DCU.
Key Features
- IP 51 compliant
- Converts any electronic energy meter into smart meter with a retrofit arrangement
- Built-in intelligent wireless communication (RF/ GSM/ GPRS) module
