NanoMeter Smart Metering & Sub-Metering
Granular energy metering at every load center, panel, and circuit for total visibility.
Overview
NanoMeter is a family of revenue-grade and sub-metering devices that measure energy consumption with ANSI C12.20 Class 0.2 accuracy. From DIN-rail-mount single-circuit meters to multi-circuit tenant metering panels with up to 84 CTs, NanoMeter provides the granular data needed for tenant billing, cost allocation, and energy optimization. All meters communicate natively with NanoGrid IQ and third-party BMS platforms.
Key Features
- ANSI C12.20 Class 0.2 revenue-grade accuracy
- Multi-circuit metering panels supporting up to 84 CT inputs per enclosure
- Revenue-grade demand, TOU (time-of-use), and power factor metering
- Split-core CTs for non-invasive retrofit installation without shutdowns
- Onboard data logging with 64 MB flash (40-day buffer at 1-min intervals)
- Native BACnet/IP, Modbus TCP/RTU, and MQTT communication
