There are many types of single-phase Electricity meter, including intelligent and mechanical ones. Different manufacturers produce different models.

1. The specifications are mainly divided into 3A, 5A, 10A, 20A, 30A, 40A, 60A, 80A, and other types.

2. Intelligent single-phase Electricity meter is commonly used for digital display, which can measure voltage and current more accurately and can be used to measure power magnitude.

3. The mechanical single-phase Electricity meter is driven by a pointer, which can intuitively measure the power, but its accuracy is low.
