Have you checked out ACI's KW Series Power Meters?

ACI's line of Power Meters and CTs will provide the power and energy usage data required to lower energy costs.

Using these meters for predictive maintenance provides additional value by identifying inefficient and under-performing equipment and calculating project ROI.

The KW Series can also be used without a traditional BAS system through on-board data logging, enabling data to be downloaded into an excel (.csv) file.
