Why Engineers Choose Titan
Titan is what panel builders also call a multifunction meter (MFM), trivector meter or network analyser. This is why engineers, facility managers and ESCOs specify it for sub-metering.
Class 0.5S, the accuracy of a billing meter
Active energy to IEC 62053-22 Class 0.5S, reactive to Class 1. Good enough to bill tenants from, not just to watch trends.
WiFi, Ethernet and RS485 in the meter
Modbus RTU/TCP, BACnet MS/TP and BACnet/IP, and MQTT straight from the DIN rail. Your BMS or cloud reads it directly, with no gateway box in the panel.
CO₂ worked out on the meter
Set an emission factor for each source (grid, diesel generator, solar) and Titan reports kg CO₂ alongside kWh, ready for Scope 2 and ESG reports.
Logs and alarms without a PC
Load profile, maximum demand, up to 8 TOU zones and an event log are stored on the meter. A relay output can trip an alarm or contactor when a limit is crossed.
Finds what the main bill hides
Metering each feeder shows the idle loads, bad schedules and low power factor that one building-level meter averages away.

How Titan Compares
Titan against a typical 3-phase DIN rail meter — across the features that matter for IoT-era sub-metering.
| Feature | Titan | Typical DIN Rail Meter |
|---|---|---|
| WiFi | Built-in | Requires external gateway |
| Ethernet | Built-in | Premium models only |
| BACnet | Built-in (MS/TP + IP) | Gateway required |
| Cloud dashboard | Platform subscription | Gateway + software licence |
| Accuracy | Class 0.5S | 0.5S premium, 1.0 standard |
| MQTT | Yes | Rarely |
| CO₂ on-device | Yes | Separate software |
| Harmonics | 31st per phase | Often limited to 15th |
| Mobile commissioning | Phone app | Laptop + proprietary software |
A 20-meter deployment with Titan needs 20 meters and your existing WiFi. The same deployment with traditional meters needs 20 meters plus 1–2 gateways, gateway power supplies, network connections, software licences, and annual fees.

Frequently Asked Questions
Common questions about Titan's accuracy, connectivity, form factor, and integration.
Getting data into your own system
Titan is not a closed device. Every data path can be pointed at your own infrastructure — none of them require a Tech OVN server. The platform is there if you want it, not because the meter needs it.
| Interface | Use it for | Goes to |
|---|---|---|
| Modbus RTU (RS485) | Polling registers from a PLC, BMS or SCADA | Your local bus — no internet |
| Modbus TCP (port 502) | The same register map over Ethernet | Your local network |
| BACnet MS/TP | Serial BACnet for a building BMS — selectable instead of Modbus RTU | Your RS485 bus — no internet |
| BACnet/IP | The same data to a BMS over the network | Your local network |
| MQTT | Continuous publish of live data and events | Any broker you configure |
| HTTP / HTTPS push | Device posts a JSON frame on its own schedule | An endpoint you specify |
| TCP/IP push | Raw socket push where HTTP isn't wanted | A host and port you set |
| REST (provisioning) | Commissioning, network setup, OTA updates | Served by the meter itself |
The published register map covers per-phase voltage, current, power factor, frequency, phase angles and THD, active/reactive/apparent power, and nine-register energy blocks for import, export and net — repeated separately for grid and DG supply, so generator-run consumption is billed apart from grid without any post-processing. Time-of-day zones, the real-time clock, relay control and maximum demand are all configurable over the same interface.
