Internal Structural Features That Distinguish Between Single-compartment And Dual-compartment Smart Meters

The single-compartment single phase smart energy meter is typically designed for single-phase power supply systems. Its measurement module, voltage sampling, and current sensing components are integrated into a single space, and data is transmitted to external systems via an internally embedded communication module. Components such as the measurement chip, high-speed processor, and real-time clock are tightly packed, enabling the device to perform metering and data processing tasks within a limited volume.

In contrast, the dual-compartment smart wifi energy meter is internally divided into two independent areas, housing the main metering module and the auxiliary communication or control module respectively. This partitioning facilitates electrical isolation between modules, reducing the possibility of mutual interference, while also providing space for back-end interfaces and expansion functions. In the dual-compartment design, the metering section still includes a sampling converter, data storage, and processor, while the other compartment serves as the area for communication, protocol conversion, and external connections.
