Energy Meters
An energy meter is a crucial device that measures and records the amount of electrical energy consumed by a home, business, or industrial facility, primarily for accurate billing by utility companies. These devices work by measuring instantaneous voltage and current, integrating these values over time to calculate total usage in kilowatt-hours (kWh). The technology has evolved from traditional electromechanical (analog) meters, which use a spinning disk, to modern electronic (digital) meters that use microprocessors for greater accuracy. The latest iteration, smart meters, provides two-way communication and real-time data, allowing for remote monitoring, time-of-use (TOU) pricing, and better overall grid management and energy efficiency.
