Electricity meters – a tool for better energy management
Electricity meters – a tool for better energy management
Electricity meters play a central role in modern energy management. They allow you to monitor your electricity consumption in real time, detect unnecessary usage and optimise your habits. Whether you want better control over your household’s energy consumption or wish to integrate the meter into a smart home system, there are many solutions that can help you save both energy and money.
In this article, you’ll get an overview of the most important considerations when choosing an electricity meter, the different types and features on the market, as well as insight into some of the most well-known manufacturers.
The article presents a wide range of electricity meters – from simple models to advanced smart meters. The aim is to provide an informative overview of features, characteristics and areas of application, so you can more easily find a solution that suits your needs. The information about the products is based on publicly available descriptions from manufacturers and retailers and is summarised to provide a clear and neutral overview.
Factors to consider when buying an electricity meter
When choosing an electricity meter, there are several factors to consider – both technical and practical. Here are some of the most important considerations.
1. Measurement accuracy and features
Accuracy is crucial for obtaining a true picture of your electricity consumption. Most modern electricity meters have high precision, but some models offer additional features such as phase-by-phase measurement, voltage quality monitoring and recording of current peaks.
2. Reading and data access
Consider how you want to read the data. Many newer electricity meters have digital displays or can be connected to an app or computer, allowing you to monitor consumption in real time. Smart meters can even send data automatically to the electricity company, making reading easier.
3. Installation and compatibility
Some electricity meters require professional installation, while others can be plugged directly into a socket or mounted on the electrical panel without major intervention. Make sure the chosen model fits your electrical system and any smart home devices.
4. Data storage and security
If the electricity meter collects and transmits data digitally, you should be aware of data security. Choose a model from a manufacturer that prioritises encryption and secure data handling.
5. Price and area of use
The price depends on functionality and technology. Simple plug-in meters are often inexpensive and suitable for measuring the consumption of individual appliances, while advanced smart meters for the entire household cost more but provide a much more detailed overview.

Different types of electricity meters
Electricity meters come in many variants that differ in function, technology and area of use. Here is an overview of the most common types.
1. Mechanical electricity meters
The traditional mechanical electricity meters, often with a rotating disc, are still used in many older installations. They are robust and reliable but require manual reading and provide no detailed insight into consumption.
2. Digital electricity meters
Digital models display consumption on a screen and can often store data over time. They are more accurate than mechanical meters and make it easier to track changes in electricity consumption.
3. Smart meters
Smart meters are the latest generation of electricity meters. They communicate automatically with the electricity company and can be integrated into smart home systems. They provide detailed information about consumption patterns and make it possible to respond quickly to changes in energy use.
4. Plug-in electricity meters
These small, portable meters plug directly into a socket and are used to measure the consumption of individual appliances. They are ideal for identifying energy guzzlers in the home and require no installation.
5. Industrial electricity meters
For larger buildings and businesses, there are advanced meters that can handle high loads and multiple phases. They are often used for energy management in companies and buildings with complex electrical installations.
Different brands of electricity meters
The market for electricity meters includes many manufacturers, each with their own focus areas and technological strengths.
Kamstrup
Kamstrup is a Danish manufacturer known for its intelligent metering solutions for both private and commercial use. Their smart meters are widely used in the energy sector and are known for high precision and secure data transmission.
Schneider Electric
Schneider Electric offers a wide range of electricity meters for both households and industrial use. The products focus on energy efficiency, integration and user-friendliness.
Siemens
Siemens produces advanced metering systems that combine precision with modern communication technologies. They are often used in larger installations and smart grid solutions.
Eastron
Eastron provides affordable and reliable electricity meters for both private and professional users. Their models range from simple DIN rail meters to advanced units with Modbus communication.
ABB
ABB is a global player in electrical components and offers electricity meters focusing on accuracy, durability and integration into automated systems.
Frequently asked questions
What is the difference between a regular electricity meter and a smart meter?
A regular electricity meter requires manual reading, while a smart meter automatically sends data to the electricity company and gives you access to detailed consumption data via an app or web portal.
Can I install an electricity meter myself?
Simple plug-in electricity meters can be connected by yourself, but meters that need to be integrated into the electrical panel must be installed by an authorised electrician to ensure correct and legal installation.
How can an electricity meter help me save electricity?
By monitoring your consumption in real time, you can identify appliances that use a lot of electricity and change your habits. This gives you better control and can lead to lower electricity bills.
Is my data safe with a smart meter?
Most manufacturers use encryption and secure communication protocols. However, it is always a good idea to choose a model from a reputable manufacturer with a focus on data security.
How often should an electricity meter be replaced?
Electricity meters typically have a lifespan of 10–15 years. Smart meters, however, can be updated via software, which extends their usability and ensures they keep up with technological requirements.
