Why Specify a Tech OVN Energy Meter

Four capabilities that run through every Titan meter — from core energy metering to thermal, EV, and condition monitoring variants.

Utility-Grade Accuracy

Class 0.5S per IEC 62053-22 across the Titan range. Metrological precision suitable for revenue metering, sub-metering, and energy audits that stand up to scrutiny.

Triple Connectivity

WiFi, Ethernet, and RS485 built into every meter. Modbus RTU/TCP + MQTT simultaneously. Feed BMS, SCADA, and cloud platforms at the same time — no gateway required.

Compact DIN Rail

Every Titan meter sits in a 94 × 89 × 69 mm DIN rail housing — fits inside the same control panel as building electrical metering and chiller controls, no separate enclosure or civil work.

Edge Computing

On-device demand profiling, harmonic analysis, CO₂ tracking, tariff registers, and event logging — intelligence that doesn't depend on cloud availability.

Engineered in India — Built for Global Deployment

Tech OVN operates a 7.5 acre manufacturing facility — the engineering heart of OVN Engineers, powering India since 1949. Every Titan meter is designed, assembled, calibrated, and tested in-house, giving us full control over accuracy and reliability over a 10-year operational life.

Standards Compliance

  • IEC 62052-11 — General requirements for electricity metering equipment
  • IEC 62053-21 — AC active energy metering, Class 1 & 2
  • IEC 62053-22 — AC active energy metering, Class 0.2S & 0.5S
  • IEC 61010 — Safety requirements for electrical measurement
  • IEC 61000 — Electromagnetic compatibility (EMC)
  • EN 1434 — Heat meters (Titan BTU family)

Platform & App — The Data Layer Above the Meters

Every Titan meter works standalone via Modbus, MQTT, or any BMS — but when you need dashboards, multi-site portfolios, and ESG reporting, Tech OVN provides the cloud-based Energy Management System (EMS) and the Titan App for commissioning and on-site audit reports from your phone.

Energy Meter Variants & Ratings

Single-phase and three-phase energy meters across the common Indian and export voltage and current ratings — direct-connected or CT-operated, DIN rail, with RS485 Modbus, Modbus TCP, and MQTT. Need a specific rating, connector, or register map? We manufacture and supply to spec.

Frequently Asked Questions

Common questions about the Titan energy meter family, manufacturing, and standards.

All Titan energy meters are manufactured in-house at our 7.5 acre facility in India. The facility handles design, PCB assembly, calibration, testing, and final packaging end-to-end.
The Titan family is Tech OVN's complete range of DIN rail smart energy meters and monitoring devices — Titan (core smart energy meter), Titan Audit (rapid-deploy logger), Titan EV (charger controller), Titan PQ (power quality), Titan Asset (condition monitoring), Titan BTU/Plus BTU (thermal metering), and Titan Compliance (fire pump monitor).
Yes. Titan meters are Class 0.5S per IEC 62053-22 with IEC type-test certification. Our utility-grade smart meters comply with IS 16444 and DLMS/COSEM for AMISP deployments in India.
Tech OVN is an OEM energy meter manufacturer and direct supplier — we design, build, calibrate, and test every meter in-house in India and supply directly, with no reseller markup. Catalogue meters ship with no MOQ (single units to hundreds); white-label / OEM with custom branding and Modbus register maps has a 200-unit MOQ. Standard lead time is 4 weeks from PO.
The range covers single-phase and three-phase systems from 57.7 V to 277 V per phase — suitable for 110 V, 220 V, 230 V, 240 V, 277 V and 400/415/480 V supplies — with direct-connected meters up to 100 A and CT-operated variants for CT primaries from 10 A to 1000 A. All in a compact DIN rail form factor with RS485 Modbus, Modbus TCP, and MQTT.
Yes, particularly for EV charger controllers and for large-volume sub-metering deployments. Contact us with your requirements for custom firmware, branding, and connector configurations.
Modbus RTU over RS485, Modbus TCP over Ethernet, and MQTT over WiFi or Ethernet — all supported simultaneously on the same meter. DLMS/COSEM is supported on utility-grade variants.
