Energy Metering for Factories

Sub-Meter Everything. See the Waste. Catch Failures Early.

Class 0.5S 3-phase energy meters and condition-monitoring hardware for Indian factories — designed for hot switchboards and round-the-clock production shifts, with HT incomers metered via customer-installed CTs and PTs. Sub-meter every major feeder, support your BEE PAT and ISO 50001 workflows with measured data, and catch developing motor faults before unplanned downtime.

Why factories sub-meter everything

Four reasons Indian factories meter every major circuit.

Sub-Meter Every Major Load

Bill reconciliation is the start, not the end. The useful insight comes from metering compressors, HVAC, chillers, and production lines individually — so you can see which line's consumption is creeping up, which motor is ageing, and where the waste is.

Supports BEE PAT & ISO 50001 Workflows

Class 0.5S accuracy with time-stamped logging gives your energy manager and accredited auditor the measured data that BEE Perform-Achieve-Trade (PAT) reporting and an ISO 50001 EnMS rely on. Report from data, not spreadsheets.

Condition Monitoring on DIN Rail

Add vibration and temperature sensing to critical motors. Titan Asset flags developing bearing wear and winding problems, typically weeks in advance of failure, so maintenance can be planned — in one DIN-rail device.

Power Factor & Demand Visibility

Harmonics and THD to the 31st order plus max-demand registers. Spot PF problems, lightly loaded transformers, and contract-demand over-runs before the DISCOM bill arrives.

The full factory stack

From HT incomer to critical motor — the meters and monitors most Indian factories deploy.

Main Incomer — Bill Reconciliation

One Titan Class 0.5S meter on the LT incomer — or on an HT incomer via customer-installed CTs and PTs. Cross-checks the DISCOM bill, logs power-factor trends, tracks max demand against contracted kVA.

Feeder-Level Sub-Metering

Titan meters on compressor, chiller, HVAC, lighting, production-line, and DG feeders. Size the meter count and CTs with our Energy Meter Sizing tool.

Condition Monitoring on Critical Assets

Titan Asset on pumps, compressors, and drive motors. Inrush capture + vibration FFT + temperature flags degradation early.

Fire Pump Compliance

Titan Compliance on fire-pump feeders. Auto-logs pump test runs to support NFPA 25 / IS 15301 record-keeping, catches missed tests, and flags possible system leaks from jockey-pump cycling.

From audit to continuous monitoring

Many factories start with a one-time energy audit by their auditor — a portable logger on each major feeder for a week or two, followed by a report of the top energy-loss patterns. That works, but it's a snapshot. Continuous sub-metering shows more, because most factory inefficiency is intermittent: a compressor that cycles badly on humid days, a chiller whose efficiency slips after a maintenance cycle, a lighting circuit that stays on because nobody remembered to reset the timer.

A common path: your auditor uses Titan Audit for the initial clamp-on survey (split-core CTs, no shutdown), then permanent Titan meters go on the largest feeders for ongoing tracking. Data flows to our Energy Management System or to your existing SCADA/BMS via Modbus TCP, BACnet or MQTT.

For factories with fire-suppression systems, the same stack covers compliance — Titan Compliance monitors the pump automatically, logs every test run, and flags missed schedules before the fire inspector does.

Frequently asked questions

Six questions factory plant engineers and energy managers ask before specifying meters.

For a typical Indian factory, a Class 0.5S 3-phase DIN rail meter with WiFi / Ethernet / RS485 is the right default. Class 0.5S (IEC 62053-22) gives you accurate sub-metering; separate comms mean you can publish MQTT over WiFi/Ethernet to a cloud platform while the RS485 port serves a legacy BMS. RS485 runs one role at a time (Modbus RTU slave, Modbus RTU master or BACnet MS/TP); the Ethernet/WiFi side (Modbus TCP, MQTT, REST, BACnet/IP) runs separately. Titan from Tech OVN is built for exactly this use case — CTs from 100 A to 1000 A (5 A secondary, Class 0.5S CTs) cover main incomer to small feeders.
Start with one meter on the main incomer and one on each of the largest feeders by consumption (compressor, HVAC plant, chiller plant, production lines, lighting, DG). Granular data is what shows you where energy goes, so err on the side of more meters. Our Energy Meter Sizing calculator gives a tailored BOQ based on your single-line diagram.
They support it. Under BEE PAT (Perform, Achieve, Trade), designated consumers report Specific Energy Consumption (SEC) against a baseline, and their figures are checked by an accredited energy auditor. Section-wise sub-metering with Class 0.5S accuracy gives you measured, time-stamped data to support those PAT workflows. The same data supports an ISO 50001 Energy Management System. The meters themselves are not "PAT certified" — compliance is about your plant's performance and reporting.
Three-step: (1) Install sub-meters on all major feeders so you can see who is consuming what. (2) Identify the top consumers and have your energy auditor study each — Titan Audit's split-core CTs give them clamp-on measurements without a shutdown. (3) Implement the recommendations — commonly power-factor correction, compressor right-sizing, chiller optimisation, LED retrofit, and load-shifting to off-peak — and use the sub-meters to verify the result.
Yes. All Titan meters publish over MQTT, Modbus TCP, BACnet and a REST API — so a single dashboard can show real-time consumption for 50+ meters across your plant. Our Energy Intelligence Platform provides this out of the box (factory-wide heat-maps, benchmarking, alerts); or you can stream to your existing SCADA / BMS / BI tool. All open protocols, no vendor lock-in.
Yes. Send us your single-line diagram and feeder list and we size the CTs for each feeder (100, 200, 400, 600, 800 or 1000 A, 5 A secondary, Class 0.5S), specify the meter count and support commissioning and integration with your BMS or our platform; your electrical contractor does the site installation. Catalogue meters ship from stock for regular orders; orders of 200 units or more take about 4 weeks.
