Titan — 3 Phase Smart Energy Meter
Precision Metering. Actionable Intelligence.
Utility-grade 3 phase DIN rail energy metering with built-in WiFi, Ethernet and RS485 — designed for buildings, industry, and global deployment.
The Energy Visibility Gap
Buildings consume 30 to 40% of global energy, yet most operators lack visibility into where energy is actually wasted. Regulatory mandates — from the EU, UAE, India and beyond — now demand circuit-level monitoring and sub-metering, not just building-level billing.
Track equipment runtime, duty cycles, and consumption patterns to detect early signs of degradation — turning every metering point into a condition monitoring sensor.
Titan bridges this gap — utility-grade accuracy meets IoT connectivity in a compact DIN rail form factor, purpose-built for real-time energy monitoring.
Why Engineers Choose Titan
Six reasons engineers, facility managers, and ESCOs specify Titan for serious sub-metering work.
Utility-Grade Accuracy
Class 0.5S per IEC 62053. Metrological precision for revenue-grade and monitoring applications.
Triple Connectivity
WiFi, Ethernet, and RS485 with Modbus RTU/TCP and MQTT. Internet-first cloud analytics with legacy BMS support — no gateway hardware needed.
Built-in CO₂ Tracking
Real-time CO₂ emissions on-device using configurable grid emission factors. Scope 2 data ready for ESG reporting and CSRD compliance. Configure per source — grid, diesel generator, solar.
Edge Computing
On-device data logging, demand profiling, TOU registers, and real-time edge analytics. Autonomous alerts and power disconnection when thresholds are exceeded.
Cost Savings
Granular sub-metering identifies energy waste that bulk billing misses — phantom loads, inefficient schedules, poor power factor penalties. Titan typically pays for itself within 6–12 months.
Fast Deployment
Configure in minutes using the Tech OVN smartphone app. No laptops, no proprietary software, no serial cables. Connect over WiFi, scan QR code, enter credentials, done.
System Architecture
Titan sits between any electrical circuit and any data destination — cloud, BMS, or analytics platform of your choice.

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 |
| Cloud dashboard | Platform subscription | Gateway + software licence |
| DIN rail width | 4 modules (72mm) | 5–6 modules |
| Accuracy | Class 0.5S | 0.5S premium, 1.0 standard |
| MQTT | Yes | Rarely |
