Electricity meters – future measurement methods explained
Electricity meters – future measurement methods explained
Electricity meters play a central role in the green transition and in our understanding of energy consumption in the home. The latest models make it possible to monitor electricity consumption in real time, analyse data and identify potential savings. At the same time, they are an important part of the smart grid, where energy consumption and production become more flexible and digitally controlled.
In this article, you will get an overview of what you should know before choosing an electricity meter, what types exist, and which features may be relevant for you as a homeowner.
The article presents a wide range of electricity meters – from simple models to advanced digital solutions. The aim is to provide an overview of functions, features and areas of application, so you can more easily find the type of electricity meter that best suits your home. The information about the products is based on publicly available descriptions from manufacturers and retailers and is summarised to provide a clear and informative overview.
Factors to consider when buying an electricity meter
When choosing an electricity meter, it is important to take into account both technical requirements, functionality and future-proofing. Here are some of the most important factors you should consider.
1. Measurement principle and accuracy
Electricity meters come with different measurement principles – from electromechanical to fully electronic models. The digital electricity meters are the most accurate and can register even small variations in consumption. For homeowners who want precise billing and insight into energy consumption, an electronic model is often the best choice.
2. Reading and data access
Modern electricity meters can be read automatically via remote reading, which saves time and ensures that you always have access to updated data. Some models allow access to consumption data via an app or web portal, so you can easily monitor your electricity consumption and adjust habits as needed.
3. Compatibility with smart home systems
If you already have a smart home system, it may be an advantage to choose an electricity meter that can be integrated with it. This makes it possible to automate energy consumption – for example, by letting the heat pump or electric car charge when the electricity price is lowest.
4. Installation and approval
Electricity meters must be installed by an authorised electrician, and it is important that the meter is approved for use in Denmark. Always check that it meets current standards and requirements from your electricity company to avoid problems with billing and operation.
5. Price and features
The price of electricity meters varies depending on features and technology. Simple models cover basic needs, while advanced meters offer detailed data analysis and integration with energy management systems. Consider which features you actually need so you get the best value for money.

Different types of electricity meters
Electricity meters come in several variants that differ in technology, functionality and area of application. The choice depends on whether you want a simple meter for recording consumption or an advanced solution for energy management.
1. Mechanical electricity meters
The classic mechanical electricity meters work with a rotating disc principle and have for many years been standard in Danish homes. They are reliable and require minimal maintenance but offer no possibility for digital reading or data analysis.
2. Electronic electricity meters
Electronic electricity meters have replaced most mechanical models. They measure electricity consumption digitally and can display detailed data on consumption and load. Many of them support remote reading and can communicate with the energy company’s systems.
3. Smart meters (intelligent electricity meters)
The intelligent electricity meters are the next step in development. They can communicate two-way with the electricity company, record consumption hour by hour and give the user access to detailed consumption data. This makes it possible to optimise energy consumption and take advantage of variable electricity prices.
4. Sub-meters
Sub-meters are typically used to measure consumption in specific parts of the house – for example for a heat pump, electric car or rental unit. They provide a more detailed picture of where the energy is used and can help identify potential savings.
Different brands of electricity meters
The market for electricity meters includes a number of manufacturers, each with their own focus areas and technological strengths.
Kamstrup
Kamstrup is a Danish manufacturer that is a leader in intelligent metering solutions. Their electricity meters are known for high precision, robustness and advanced communication technology, making them suitable for both private and commercial use.
Landis+Gyr
Landis+Gyr has for many years supplied metering solutions to the energy sector and offers a wide range of electronic and intelligent electricity meters. The brand emphasises data security and flexibility in integration with energy management systems.
Schneider Electric
Schneider Electric produces electricity meters that combine accuracy with advanced data analysis. Their products are aimed at both private homes and larger buildings, where energy management and monitoring play a central role.
Siemens
Siemens offers electricity meters with a focus on precision and reliability. Many of their models can be integrated into larger automation systems, making them popular in both industry and modern homes.
Iskraemeco
Iskraemeco supplies smart meters with a focus on sustainability and energy efficiency. Their solutions support advanced data collection and are designed to operate seamlessly in smart grids.
Frequently asked questions
What is the difference between a regular and an intelligent electricity meter?
A regular electricity meter only records total consumption, while an intelligent electricity meter can display detailed data on consumption over time and communicate directly with the electricity company. This provides better insight and the opportunity to optimise energy consumption.
Can I install an electricity meter myself?
No, installation of electricity meters must be carried out by an authorised electrician. This ensures correct connection, accurate measurement and compliance with current safety standards.
How do I read my electricity meter?
Most modern electricity meters are read automatically, but you can also read the display manually. On digital models, you can typically see both current consumption and total consumption via menus on the screen.
Are intelligent electricity meters safe?
Yes, intelligent electricity meters are designed with high data security and encryption. They only transmit consumption data and cannot be used to control appliances in the home without your permission.
Can an electricity meter help me save electricity?
Yes, by providing insight into your consumption, an electricity meter can help you identify where you use the most electricity and where you can reduce consumption. Combined with energy management, this can lead to noticeable savings.
