Multi rate smart meterIt is an advanced energy metering device with time-sharing metering function, which can automatically record the user's electricity consumption during different time periods (such as peak, off peak, off peak, and off peak) set by the power department, and charge according to the corresponding electricity prices. It is not only an upgraded substitute for traditional electricity meters, but also a key terminal device in the construction of smart grids, widely used for refined electricity management and demand side response for residential, commercial, and industrial users.

The meter is based on a high-precision electronic metering chip, integrating real-time clock (RTC), microprocessor, memory, communication module (such as RS485, carrier, LoRa, NB IoT or 4G) and LCD display unit. Its core functions include: precise measurement of active/reactive energy, voltage, current, power factor and other parameters; Support automatic switching between multiple time periods (usually 4-8 rate periods); Equipped with intelligent features such as event recording (such as power outage, lid opening, overload), remote meter reading, remote control (power on/off), load monitoring, and abnormal alarm.

　　Multi rate smart meterDetailed description of its main features:

1、 High precision metrology and data processing capabilities

By using high-precision measurement chips (such as ADE7755), the energy measurement error is ensured to be less than 1%, meeting the precise measurement needs of industry, commerce, and public facilities. Its powerful data processing capability not only supports basic electricity metering, but also calculates parameters such as power and demand, providing data support for power companies to formulate differentiated electricity pricing strategies. For example, by real-time monitoring of user electricity load characteristics, power factor and reactive power compensation strategies can be optimized to reduce grid losses.

2、 Time of use measurement and flexible rate setting

This meter can automatically switch between different tariff levels based on the peak, off peak, off peak, and off peak periods set by the power company, achieving time-sharing metering. Users can adjust their electricity consumption behavior based on fluctuations in electricity prices, such as activating high energy consuming equipment during off peak periods to reduce overall electricity expenses. At the same time, the electricity meter supports flexible time period setting function, which can customize the metering time period according to regional electricity price policies or user needs, adapting to diverse electricity consumption modes.

3、 Remote Communication and Automation Management

Equipped with communication interfaces such as infrared, RS-485, 4G-Cat1, etc., the multi rate smart meter supports automatic meter reading and remote data transmission, achieving real-time monitoring of user electricity information by the power company. Through a remote management platform, power companies can dynamically adjust their electricity pricing strategies, monitor grid loads, and quickly respond to abnormal electricity usage behaviors (such as electricity theft or equipment failures). In addition, the electricity meter supports demand side management, providing a data foundation for implementing demand response strategies and helping the power grid balance supply and demand.

4、 Anti interference design and environmental adaptability

During the PCB design phase, lightning protection circuits and optoelectronic isolation technology are used to separate communication circuits from other circuits, significantly reducing the risk of lightning damage to the electricity meter. At the same time, the modular structure and galvanized shielding plate are used to isolate strong and weak electrical signals, reducing the impact of electromagnetic interference on measurement accuracy. Some models also have a power phase loss indication function, which can still work normally when there is a phase loss in three-phase power supply, adapting to complex power grid environments.

5、 Data Security and User Privacy Protection

Advanced encryption algorithms are used to encrypt, store, and transmit electrical energy data, preventing it from being illegally obtained or tampered with. By implementing strict access control mechanisms, only authorized users are allowed to view meter data, ensuring user privacy. In addition, the power-off data protection function can automatically save critical data in the event of a sudden power outage, avoiding information loss.

6、 Energy conservation, consumption reduction and resource optimization

The time of use billing mechanism encourages users to concentrate electricity consumption during off peak periods, disperse peak loads, and effectively alleviate the pressure on the power grid. For example, commercial venues can reduce peak electricity demand and carbon emissions by adjusting the operating time of air conditioning, lighting, and other equipment. For industrial users, precise measurement and remote monitoring functions help optimize production processes, reduce unit product energy consumption, and improve energy utilization efficiency.

7、 Intelligent interaction and user experience

Some models are equipped with LCD screens, which can display real-time information such as household number, accumulated power, remaining power, voltage, current, power, electricity price, etc., and improve readability through controllable backlighting. Users can query electricity usage details and develop personalized electricity plans through infrared remote control or mobile applications. For example, household users can adjust the charging time of electric vehicles according to changes in electricity prices to achieve economical electricity consumption.
