◆Overview
The Elsource Three Phase Smart Meter is a high-accuracy, DLMS-compliant static energy meter engineered for industrial, commercial and utility metering points where revenue accuracy, power quality visibility and remote acquisition are non-negotiable. It targets Class 0.5s / Class 1 accuracy per IS 16444, IS 15959 and IEC 62053.
Available in CT-operated and direct-connected variants for 3-phase 4-wire LT and MV service positions, the meter measures active, reactive and apparent energy in both import and export directions. Maximum demand, load survey, tamper events and power-quality snapshots are held in non-volatile memory and made available through DLMS/COSEM over PLC / RF / GPRS / NBIoT communications options and supports data exchange with utility Head-end and MDM platform.
Deployed at incomer bays, HT-LT interfaces, shop-floor buses and data-centre PDU feeds, the meter serves as the source of truth for energy accounting, tariff optimisation and audit — feeding Elsource EMS as well as third-party SCADA, MDM and BMS platforms.
◆Key capabilities
What sets this smart meter apart on the panel.
Class 0.5s / Class 1 revenue-grade accuracy
Suitable for HT/LT boundary and industrial billing metering points; aligned with IS 14697 / IS 13779 & IEC 62053 22 / IEC 62053 21.
Bi-directional energy
Independent import and export registers for active, reactive and apparent energy — suitable for solar net-metering scenarios.
Maximum demand & load survey
Configurable demand integration period and load profile channels for tariff and demand-side analysis.
Power quality snapshot
Per-phase voltage/current, unbalance, power factor and frequency for shop-floor diagnostics.
DLMS/COSEM & Modbus
Standards-first communication for clean integration with utility head-end and enterprise EMS.
Non-volatile event log
Tamper, power-fail, phase-fail and configuration events with time stamps and sequence numbers.

◆Where it's deployed
Field-proven across the sectors that need accuracy.
A cross-section of the deployments this meter is engineered for. Talk to us about your specific site.
Commercial real estate
HT-LT boundary and floor-level metering feeding tenant billing and portfolio dashboards.
Data centres
PDU and UPS-level metering supporting PUE calculation and redundant polling.
Utilities
Feeder metering with DLMS head-end integration for revenue protection and outage analytics.
Solar
Net-metering interface with bi-directional import/export registers for PPA reconciliation.
◆Works with
Standards-first. Integrates in days, not months.
Elsource meters ship with the protocols and register maps that head-end, SCADA, BMS and EMS platforms already understand — so the integration effort stays measured.
- Elsource On-Premises & Cloud EMS
- Elsource Tenant Billing platform
- Utility head-end / MDM systems (DLMS)
- SCADA & DCS via Modbus / DLMS gateways
- BMS and DCIM platforms
◆FAQ
Questions engineers actually ask.
What accuracy class is available?
The three-phase meter is available in Class 0.5s and Class 1 variants, aligned with IEC 62053 and IS 16444 requirements.
Does the meter support bi-directional (net) metering?
Yes. Independent import and export registers for active, reactive and apparent energy make it suitable for solar net-metering and PPA scenarios.
Does it support RF/cellular communication?
Select variants support RF/cellular communication for remote acquisition and integration with utility head-end and enterprise EMS platforms.
Is Modbus supported?
Select variants support Modbus RTU on RS485 for direct integration with SCADA, DCS and BMS platforms that do not yet speak DLMS.
