Satec BFM136 Multi-channel Submeter

The Satec BFM136 Multi Channel Energy Monitor Submetering may track up to 12 circuits in three phases, 36 circuits in one phase, or any combination of one phase and three phases. The BFM136 is perfect for multi-tenant buildings including office towers, shopping malls, and residential developments because of its versatility.

This little instrument fits into existing panel boards or can be flush mounted nearby, so there’s no need to invest in costly conversion projects or set aside extra space for it.
