Allocating these costs provides accountability for energy use on campuses and allows businesses to accurate determine the cost of projects and services. For each building or department, the facility manager installs the necessary sensors and meters to isolate and measure the energy used by that department. On a monthly basis, the data from the DAS is analyzed to produce a cost for energy assignable to the department. For most energy and facility managers, there are benefits and payback to investing in the hardware and software to submeter campuses or industrial facilities.** [**Learn More About Power Meter**](https://www.setra.com/contact-us?description=I+want+to+learn+more+about+the+Setra+Power+Meter) [**Power Meter Product Page**](https://www.setra.com/product/power-meters/setra-power-meter) ![setra-systems-power-meters](https://www.setra.com/hs-fs/hubfs/setra-systems-power-meters.png?width=309&name=setra-systems-power-meters.png) **Submetering Simplified** **Setra Power Meter** [![setra-systems-power-meters](https://www.setra.com/hs-fs/hubfs/setra-systems-power-meters.png?width=250&name=setra-systems-power-meters.png)](https://www.setra.com/product/power-meters/setra-power-meter) Available in 3, 12, and 48 load options. The Power Meter from Setra is a networked revenue-grade power meter built on a versatile and powerful platform designed to meet the high demands for any submetering application.
