What is an Electricity Meter?
Electricity metering is the process of measuring the instantaneous voltage and current in order to calculate the consumed electric energy which is typically calibrated into billing units such as kilowatt hour (kWh). Electricity metering is a broad term which includes both AC and DC metering.
How To Meter Electricity
How you measure your electricity will be dependent primarily on what the application is, with a multifunction meter such as the Acuvim II series there are many versatile capabilities allowing for the most productive use. Conversely in specific applications such as renewable energy monitoring a more specialized tool such as the AcuDC 243 meter may be required, and in multi-tenant metering a multi-channel input meter such as the AcuRev 2020 would be most effective.
