Different Types of Smart Meters You Should Know About
There are two main types of smart meters that you might have installed at your home or business. Understanding the difference between them can help you know what to expect.
- Electricity Smart Meters measure how much electricity you use. They count this in units called kilowatt-hours (kWh). These meters can tell you exactly how much electricity you used at different times during the day. For instance, you might learn that you use more electricity in the morning when everyone is getting ready for work or school, and again in the evening when people come home.
- Gas Smart Meters keep track of how much natural gas you use for heating, cooking, or hot water. They measure gas in cubic meters or cubic feet. Just like electricity smart meters, they can show you when you use the most gas during the day or year.
Both types of meters work as part of something called Advanced Metering Infrastructure, or AMI for short. AMI is a fancy name for systems that measure, store, and study energy use data. These systems can work with different types of meters, including those for electricity, gas, and even water.
How Smart Meters Work
Smart meters use special technology to talk back and forth with your utility company. This two-way communication happens through wireless networks, much like how your cell phone connects to towers to make calls or send messages.
Two-Way Communication
The communication between your smart meter and the utility company usually happens through cellular networks or radio frequency signals. This means the meter can send information about your energy use to the company, and the company can send information back to your meter.
