Public utility companies generally meter whatever product they provide to their customers. The product may be electricity, water, natural gas, steam or any other resource provided by the utility company Submetering is the use of one or more other meters so he can allocate his usage of that product. It is most frequently used so that tenants can be charged for what they used, but it is also done for cost analysis in manufacturing plants and, in the case of electricity, for projecting equipment failure via trend analysis.
