Precision Smart Meters
Accurate energy measurement with robust connectivity and analytics for residential, commercial, and DC applications.

Industrial & Critical Infrastructure
When paired with the Joulepoint Energy Intelligence platform, our meters provide a live model of your electrical ecosystem — from where energy is generated to where every kilowatt is consumed. Ideal for hospitals, factories, large residential societies and power plants.
- Instrument feeders, panels and assets (compressors, chillers, pumps, AHUs, servers, etc.).
- Track sources: grid import, diesel gensets, solar PV and battery storage.
- Identify anomalies: imbalance, high THD, leakage currents, overheating and overloads.
- Prevent downtime: threshold alerts, guided SOPs, and automatic work orders.
- Safety & compliance: signed readings (OCMF), audit logs and calibration workflows.
Outcomes
- End‑to‑end visibility of generation, distribution and consumption.
- Reduced accidents and unplanned outages through early anomaly detection.
- Lower energy cost via power‑factor correction and demand optimisation.
- Transparent allocation for tenants/lines with exception reports.
Key Features
- Single-phase, three-phase, and DC metering options
- High accuracy classes up to 0.2s
- Connectivity: RS485, M‑Bus, Wi‑Fi, 4G
- Extended operating temperature and high IP ratings
