Lisämittari

Lisämittari is a Finnish term that translates to "additional meter" or "extra meter." In practical terms, it often refers to a secondary electricity meter installed in a property in addition to the primary, main meter. The purpose of a lisämittari can vary depending on the situation.

One common use is for sub-metering within a larger building or property. For instance, in a multi-unit dwelling, each individual apartment might have its own lisämittari to accurately measure the electricity consumption of that specific unit. This allows for fair and precise billing to each tenant based on their usage, rather than dividing the total building consumption equally. Similarly, in commercial properties, different business units or areas within a larger space might have their own lisämittari for separate accounting.

Another application can be for monitoring specific high-consumption appliances or circuits. An owner might install a lisämittari to track the energy usage of a particular piece of machinery, a workshop, or even a detached garage. This can be useful for understanding energy costs, identifying potential inefficiencies, or for tax or reimbursement purposes. The data from a lisämittari helps in a more granular understanding of electricity consumption patterns.
