What Is a Traditional Electricity Meter?
A traditional electricity meter measures the total amount of electricity used by a property over time. These meters are commonly used for basic billing and electricity consumption tracking.
Often, a traditional meter must be read manually, either by the property owner, tenant, utility provider or meter reader. The meter reading is then used to calculate electricity consumption for a billing period.
Traditional meters are useful for measuring total usage, but they usually provide limited information. They may not show detailed usage patterns, peak demand, load behaviour, import and export kWh, or real-time energy performance.
What Is a Smart Energy Meter?
A smart energy meter is a more advanced electricity monitoring device or system that can provide detailed information about electricity usage.
Depending on the meter and monitoring system, a smart energy meter can track values such as:
- kWh consumption
- Voltage
- Current
- Power factor
- Frequency
- Active power
- Reactive power
- Apparent power
- Import kWh
- Export kWh
- Load performance
- Usage patterns over time
Smart energy meters can also connect to dashboards, IoT platforms, building management systems or energy monitoring systems, depending on the communication options available.
Key Differences Between Smart Energy Meters and Traditional Meters
