Energy Metering for Data Centres
PUE. Per-Rack Billing. COP Tracking. One Meter Family.
Class 0.5S energy meters and thermal meters engineered for Indian data centres — revenue-grade for colocation billing, granular enough for PUE tracking and chiller optimisation, and compliance-ready for Tier III / Tier IV audits. Deploy at the rack, PDU, UPS, chiller, or any point on your single-line diagram.
Why data centres choose Tech OVN
Four reasons our meter stack fits the Indian data-centre profile — colo, hyperscaler, and enterprise on-prem alike.
Revenue-Grade Colocation Billing
Class 0.5S per rack or per cage for accurate customer billing. Pulse outputs integrate with DCIM and billing systems. CT-free options for post-install retrofit of live racks.
PUE Tracking Built In
Meter the IT load, the cooling load, and the facility auxiliaries separately — PUE computes automatically on the platform. Monthly, hourly, or per-zone PUE available.
Per-Subsystem Visibility
UPS efficiency, CRAC/chiller kW/TR, generator test runs, lighting, BMS. Every loss pathway becomes a data point, which is what the Tier III and ISO 50001 audits expect.
High-Density & Hot-Aisle Ready
Titan is Class 0.5S, rated to 70°C ambient, and comes in a 4-DIN rail form factor — fits inside PDU cabinets and switchboards without bespoke mounting.
The data-centre stack
From utility incomer to the fire pump — the meters most Indian data centres deploy.
Main Incomer & UPS Output
One Titan on each utility incomer, one on each UPS output. Gives you utility-fed load vs protected load, and UPS round-trip efficiency per string.
PDU & Rack-Level Metering
Titan on each PDU or per-rack feed. Feeds colocation billing and DCIM. Harmonic logging flags transformer heating before the alarm fires.
Cooling Plant — Chillers, CRACs, CRAHs
Titan Plus BTU on chilled-water loops for kW/TR and COP trending. Titan on CRAC/CRAH feeders for airflow-vs-power correlation.
Ancillaries & Fire Pumps
Titan Compliance on fire-pump feeders for automated NFPA 25 test logging — required for Tier III/IV certification. Titan on lighting, BMS, and generator feeders closes the loop.
PUE, COP, and the numbers that matter
Data-centre efficiency boils down to two ratios: PUE (total facility power ÷ IT power) and chiller COP (cooling delivered ÷ electrical input). Both require continuous, synchronous measurement — snapshot readings from clamp-on audits are close to useless because the values drift hourly with ambient, IT load, and UPS configuration.
Our typical DC deployment: Titan on the utility incomer, UPS inputs and outputs, and each PDU. Titan Plus BTU on the chilled-water loops for COP. Titan on every CRAC/CRAH feeder for airflow-per-watt. Data flows to our Energy Intelligence Platform or directly into your DCIM via Modbus TCP / MQTT / BACnet.
For colocation operators, the same Titan is also the billing meter — Class 0.5S accuracy satisfies the contract, and pulse outputs integrate with the colo billing platform. One meter family covers internal efficiency tracking AND customer billing, which is what operators typically end up wanting anyway.
