What Are the Classifications of Electric Energy Meters？(2)

1. What are the factors that need to be referenced in household electricity meters?

1). Total nuclear load power. Turn on the total power of all electrical appliances in your home, and you also need to consider the total nuclear load power of which electrical appliances will be purchased next to select the specifications and models of the meter to meet long-term needs.

2). Electric meter function. Today's electric meters already have many functions, such as active meters, reactive meters, mechanical meters, electronic meters, demand meters, multi-function meters, peak-valley time-sharing meters and so on. Here you need to look at the specific use requirements. Today's multi-function electronic watches can integrate a variety of measurement functions, but they are expensive. General mechanical watches can measure one or several functions individually, and the price is relatively cheap. The key depends on the need.

3). Measurement accuracy. Under different requirements, the accuracy required by the meter is also different. For general household electricity, it is sufficient to use a meter with an accuracy of level 2.0 or higher. In large enterprises, the gateway meter needs a meter with an accuracy of 0.5 or even 0.2. The higher the accuracy, the higher the price. This also depends on the needs of use.

4). Product quality. In the case of other factors being the same, the quality of the product is very important, and it is not necessarily expensive that it is good, and good must be expensive. However, it is best to choose large-brand products from formal channels to ensure quality and avoid adverse consequences.
