The EM133-XM represents a breakthrough in Australian energy metering: a fully NMI approved energy meter with ethernet connectivity as an option. This option provides a DIN energy meter with dual communication functions – RS485 and ethernet.
For facilities managers, electrical contractors and energy consultants, finding an NMI approved energy meter with ethernet has historically meant expensive custom solutions or settling for serial communications. The EM133-XM changes this equation by combining Class 0.5S revenue-grade accuracy with native IP networking, all in a form factor that fits standard Australian distribution boards.
At its core, the EM133-XM delivers precise metering accuracy across single or three-phase configurations. It works seamlessly with standard current transformers or high-accuracy current sensors (HACS) for retrofit applications where you can’t shut down existing systems. The compact design fits into crowded distribution boards without requiring expensive panel modifications, while built-in digital inputs and relay outputs support everything from pulse metering to automated disconnect schemes.
What sets the XM version apart is its extended memory capacity. Where standard meters struggle to retain more than a few weeks of interval data, this NMI approved energy meter with Ethernet stores years of history at intervals as fine as five minutes.
This isn’t just about having more data, it’s about having the right data at the right resolution when you need to diagnose problems, verify compliance or optimise energy usage across complex facilities.
How Ethernet Transforms NMI Approved Metering
Anyone who’s spent a Friday afternoon troubleshooting a failed RS-485 daisy chain knows the limitations of serial communications. Finding which device has dropped off the network, checking terminating resistors and tracing cable runs through crowded plant rooms eats up valuable time and delays commissioning.
The EM133-XM transforms this experience as an NMI approved energy meter with ethernet by putting revenue-grade metering directly on your IP network. With Modbus TCP/IP support, the meter integrates seamlessly with building management systems, SCADA platforms and power analysis software without requiring protocol converters or serial gateways.
For utility-grade applications, this NMI approved energy meter supports IEC 60870-5-104 over TCP, while SATEC’s Expertpower cloud platform enables secure remote monitoring and management.
Network-based connectivity changes how you work with revenue meters. Each device gets its own IP address, making it instantly identifiable and accessible. You can ping meters to verify connectivity, use standard IT tools for diagnostics and connect directly for configuration or data retrieval. Instead of wondering which device is “node 7” on a serial chain, you simply navigate to the meter by IP address and go straight to work.
The practical benefits extend beyond troubleshooting. Commissioning an energy meter with ethernet happens faster because you can verify meter operation and pull initial readings without physical access. Ongoing monitoring becomes simpler when every meter can push event notifications or serve data via its embedded web server. When problems do arise, remote diagnostics often eliminate the need for site visits entirely.
Revenue-Grade Data That Drives Decisions
As an NMI approved energy meter with Ethernet, the EM133-XM captures far more than basic energy consumption. Time-of-Use registers track energy and demand across complex tariff structures with support for eight different tariffs, four seasons and multiple daily rate changes. Four-quadrant metering accurately measures both import and export energy flows, essential for solar installations and facilities with bi-directional power flows.
The extended memory supports logging up to 16 parameters at user-defined intervals, with storage capacity measured in years rather than months. At 30-minute intervals, the meter retains over three years of data; even at five-minute intervals required for Type 4 metering, you get more than seven months of history. Event logging captures setup changes and diagnostic events automatically, creating an audit trail that supports both troubleshooting and compliance reporting.
This rich, NMI-approved dataset flows directly into the systems that matter. Utility and precinct billing systems get validated interval data without manual reads. NABERS and Green Star reporting workflows pull compliant measurements for sustainability compliance.
Cloud platforms like Expertpower slice the data for benchmarking, tenant reporting and optimisation analysis. The result is fewer data gaps, more accurate billing and a stronger foundation for identifying efficiency opportunities.
Where a NMI Approved Energy Meter With Ethernet Excels
Commercial Sub-Metering:
In multi-tenant commercial buildings, deploying an NMI approved energy meter with Ethernet at each tenant location solves the complexity of scattered meters across risers and plant rooms. IP connectivity means all tenant data flows back to a central billing platform without elaborate serial networks.
You get auditable revenue-grade billing plus the ability to overlay analytics showing peak demand patterns, diversity factors, and after-hours usage, all from the same device.
Solar and Embedded Networks
Renewable energy projects demand accurate import/export measurement and detailed time-of-use data for settlement and optimisation. Using an NMI approved energy meter with Ethernet like the EM133-XM gives you four-quadrant metering, extensive logging capability and IP connectivity for real-time visibility of generation, export and behind-the-meter loads.
This combination is essential for sites requiring both compliant billing and operational optimisation.
Precincts and Utilities
For campus and utility-scale deployments, having an NMI approved energy meter with Ethernet that supports IEC 60870-5-104 and Modbus TCP enables direct integration with existing SCADA infrastructure.
You get a single device that serves both operational visibility and compliant billing needs without custom gateways or middleware.
Future-Proofing Your NMI Approved Metering Infrastructure
Energy management standards, tariff structures and reporting requirements continue evolving. The EM133-XM as a NMI approved energy meter anticipates this by offering upgradeable firmware via serial or Ethernet connections, allowing feature updates and fixes without hardware replacement. Modular communications mean you can add or swap connectivity options as project requirements change rather than replacing entire meters.
Support for open protocols including Modbus TCP, IEC 60870-5-104 and DNP3 ensures integration with diverse third-party systems. You’re not locked into a single vendor’s ecosystem or forced to bridge incompatible protocols. As your facility’s digital strategy evolves, your NMI approved energy meter with ethernet infrastructure evolves with it.
Why the EM133-XM Is the NMI Approved Energy Meter With Ethernet You've Been Searching For
Finding a NMI approved energy meter with ethernet shouldn’t mean compromising on features, accuracy or integration capability. The EM133-XM delivers the complete package:
- Revenue-grade billing accuracy that meets Australian compliance requirements
- Extended interval data logging that captures the detail you need for analysis
- Rich power quality measurements that support both basic monitoring and advanced diagnostics
- Modern IP-based communications that integrate with SCADA, BMS, and cloud platforms using standard network infrastructure.
This combination matters because energy management increasingly demands more than simple consumption tracking. Whether you’re recovering costs through tenant billing, demonstrating sustainability compliance, optimising facility operations or managing distributed generation, you need an energy meter that delivers trusted data through systems that work with your existing infrastructure.
The EM133-XM fits the real-world constraints of Australian switchboards and plant rooms while providing capabilities that scale from single installations to campus-wide deployments. It’s a NMI approved energy meter with ethernet that’s ready for whatever your next project demands and flexible enough to adapt as those demands change.
