Tariff Energy Meters are mainly generated to adapt to changes in the market and user demand. Traditional energy meters can only realize a single metering and billing method, which cannot meet the needs of users for flexible metering and billing method. With the development of the tight power supply, in order to alleviate the shortage of electricity consumption during peak periods, guide users to use electricity during the trough period, and balance the balance of electricity consumption at various times of the day, Tariff Energy Meters came into being. The most important role of the Tariff Energy Meter is to measure electricity in different time periods, cooperate with the price system of power operators at different time periods, and achieve the role of peak shaving and valley filling, which can not only reduce the user's electricity cost, but also effectively balance the load of the power system and improve the stability of the power system.

Tariff Energy Meters have the characteristics of multiple metering and billing methods and high flexibility, which are mainly manifested in the following:

(1) Multiple metering and billing methods: The Tariff Energy Meter can realize a variety of metering and billing methods, such as time-of-use metering and billing, ladder metering and billing, peak and valley metering and billing, etc., and users can choose the metering and billing method suitable for themselves according to their own electricity consumption, which is more flexible.

(2) High precision: The Tariff Energy Meter adopts advanced electronic technology and precision sensors, which can achieve high-precision energy measurement, accurately measure current, voltage, power and other parameters, and provide reliable data support for power management.

(3) Data communication: The Tariff Energy Meter can usually realize data communication with the superior power system, and the meter data can be read remotely, avoiding the cumbersome process of manual meter reading, and improving the accuracy and efficiency of metering and billing.

(4) Anti-tamper function: In order to prevent the meter from being tampered with or stealing electric energy, the Tariff Energy Meter usually has an anti-counterfeiting function, which can encrypt and lock the meter to ensure the justice, fairness and safety of electric energy measurement.
