Comparison of Wall-Mounted and Din Rail Electricity Meters

Din rail electricity meters and wall-mounted electricity meters have significant differences in installation methods and application scenarios. However, in terms of functionality, safety, and reliability, both follow the same relevant standards for electricity meters, and both are expected to evolve toward smart solutions in the future.

Installation Methods

Din Rail Electricity Meter

Flexible installation: The Din rail electricity meter uses a standard rail mounting method, such as the common 35mm DIN rail, which makes the installation process very convenient. Simply clip the meter onto the rail to complete the installation, without the need for complex fixing and connection processes.
Space-saving: Its compact design allows the Din rail electricity meter to be easily integrated into electrical cabinets without taking up additional space. It is particularly suitable for use in distribution boxes with limited space.
Easy to replace: When the meter needs to be replaced, simply remove the old meter and clip in the new one. There is no need to rewire or adjust the installation location, making maintenance and replacement very convenient.

Wall-Mounted Electricity Meter

Wall-mounted installation: The wall-mounted electricity meter is usually installed on the wall, requiring pre-drilled holes and mounting brackets. Although the installation process is relatively simple, it may not be suitable in spaces with limited room.
Wall space usage: The wall-mounted electricity meter occupies wall space, which may not be the best choice in areas where space is tight.

Functionality and Performance

Multi-Functionality

Both Din rail electricity meters and wall-mounted electricity meters not only have basic power metering functions but also integrate various extended features. For example, they can monitor parameters such as current, voltage, and power factor in real-time, offer remote data transmission, and support time-of-use pricing. These functions make the Din rail electricity meters and wall-mounted electricity meters more comprehensive and efficient in energy management and electricity monitoring.

High-Precision Measurement

Both types of meters use advanced measurement chips and technologies, ensuring high precision and stability. They can accurately measure electricity consumption under various load conditions, meeting the requirements for accurate billing and energy management.

Remote Communication

Both types of electricity meters support multiple communication protocols and methods, such as RS485, Wi-Fi, WiFine, LoRa, 4G, and PLC. This enables remote data transmission and monitoring. Users can access their electricity usage information anytime through remote systems for effective energy management.

Safety and Reliability

Both the Din rail electricity meter and the wall-mounted electricity meter are designed with industrial-grade standards, featuring overload protection, short circuit protection, and electromagnetic interference shielding. The power connection is fully isolated, further enhancing the safety and reliability of the measurements.

Application Scenarios

Din Rail Electricity Meter

Wide application: Due to its flexibility and multifunctionality, the Din rail electricity meter is widely used in various scenarios. In industrial applications, it can be used in factories, workshops, and other industrial settings. In commercial applications, it helps manage electricity usage in shopping malls, office buildings, and similar places. Furthermore, the Din rail electricity meter is suitable for buildings, data centers, automated production lines, and other environments.

Wall-Mounted Electricity Meter

Application scenarios: Wall-mounted electricity meters are primarily used in residential, commercial, and industrial electricity applications.

Future Development Prospects

With the development of smart grids and the Internet of Things (IoT), both Din rail electricity meters and wall-mounted electricity meters are moving toward smart solutions. Their high-precision measurement, remote communication, and data analysis functions will provide users with more convenient and intelligent electricity management solutions.
