An electricity meter, electric meter, electrical meter, energy meter, or kilowatt-hour meter is a device that measures the amount of electric energy consumed by a residence, a business, or an electrically powered device over a time interval. Electric utilities use electric meters installed at customers'' premises for billing and monitoring purposes.

Power meters can measure your instantaneous power output. It is an objective metric not influenced by external factors like wind, road surface, fatigue, etc. In other words, when you push 200W to your pedals, you push 200W. This objectivity means you can train more efficiently and easily track your long-term progress.

Large commercial and industrial premises may use electronic meters which record power usage in blocks of half an hour or less. This is because most electricity grids have demand surges throughout the day, and the power company may wish to give price incentives to large customers to reduce demand at these times. These demand surges often correspond to meal time…

The AD7750 integrates two 16-bit analog-to-digital converters and the digital signal processing logic necessary to measure electrical energy. With the exception of the analog circuitry in the A/D converters and the reference circuit, all other signal processing (e.g., multiplication and filtering) is carried out in the digital domain.

To read the meter: Write down the numbers shown from left to right. Ignore numbers that come after a full stop. Ignore any numbers that are in a different colour. In this example, the meter reading is 26653. If you get cheaper electricity at certain times, you might have a two rate (or ''dual-rate'') meter.

E = ∫ Pdt (9.6.12) (9.6.12) E = ∫ P d t. is the energy used by a device using power P for a time interval t. If power is delivered at a constant rate, then then the energy can be found by E = Pt E = P t. For example, the more light bulbs burning, the greater P used; the longer they are on, the greater t is.

Help with meters. Electricity and gas meters allow us to accurately tell how much energy you''ve used. They measure energy in units – on your gas meter one unit equals one cubic metre (m3). On your electricity meter, one unit equals one kilowatt hour (kWh). Sounds complicated but it''s just an accurate way to measure how much you use.
