SATEC BFM-II – Multi-Circuit Branch Feeder Power & Energy Meter (Up to 54 Circuits)

SATEC BFM-II – Multi-Circuit Branch Feeder Power Meter

The SATEC BFM-II Branch Feeder Monitor™ is a modular, DIN-rail mounted multi-circuit power and energy meter designed to dramatically reduce installation costs and panel space compared to deploying individual meters for each load. It monitors up to 18 three-phase circuits (or 54 single-phase, or any combination) from a single device.

With Class 0.5S revenue-grade accuracy, anti-tamper design, and multi-tenant TOU billing built in, the BFM-II is the preferred choice for commercial buildings, shopping centers, office parks, and medium-voltage substations.

Multi-Circuit Metering

• Up to 18 three-phase loads or 54 single-phase loads per device
• Individual billing for each submeter (TOU): 8 energy registers × 8 tariffs
• 4 seasons × 4 day types; 8 tariff changes per day
• 120-day automatic daily energy profile per submeter
• Pulse input via DI for water and gas sub-metering
