1. It has measure forward and reverse active energy functions. Electrical energy should be accumulated and stored separately for electric energy and total electrical energy at each time period such as tips, peaks, flats, and valleys. And it can also store and display the power of the previous 12 months.
2. It can measure,store and display the voltage, current, power, power factor, frequency and other operating parameters and status of the current electricity meter. And it has overload protection function.
3. There are two sets of rates (sharp, peak, flat, valley) and periods that can be programmed arbitrarily, and another set of rates and periods can be start to used at the set time point. Each set of rate time periods can be set with at least 2 time zones for a year. At least 14 time periods can be set within 24 hours. The minimum time period interval is 15 minutes. The time period can be set across zero points.
4. It has freezing functions such as instantaneous freezing, regular freezing, daily freezing, agreed freezing and hour freezing.
5. It has the function of event recording such as zero clearing, programming, proofread, power down, pulling and closing the brake, etc.
6. Remote disconnection and power transmission function. Power off command is issued through communication interface such as RS485 to cut off the user's load loop; Or issue a power transmission instruction to turn on the user load loop.
7. Active upload / bidirectional transparent transmission function. Actively upload the data to the corresponding platform through the LoRaWAN wireless network, with a default interval of 4 hours (settable).
8. After the meter is powered on and the LoRaWAN module is connected to the network, the meter is automatically calibrated.
9. And our lorawan electricity can widely used in such scenarios:
a.Residential quarters: smart meter reading, energy-saving management, and prevention of energy waste.
b.Commercial places: saving costs, improving energy efficiency, real-time monitoring.
c.Industrial enterprises: precise measurement, remote monitoring, energy saving and emission reduction.
d.Government agencies: Unify management, reduce operating costs, and improve energy management levels.

INSTALLATION
Live installation of wiring is strictly prohibited!
The electricity meter shall be installed indoors as far as possible. Special instrument box protection shall be used for outdoor installation. The installation bottom plate shall be fixed on the wall with strong fire resistance and not easy to vibration. There must be no corrosive gases in the surrounding air where the meter is installed. Avoid dust, salt spray, etc.
When using the electricity meter, the wiring must be conducted strictly according to the wiring diagram in the tail cover of the meter. It is recommended to use copper wire for the lead connected to the terminal seat. The screws of the fixed lead in the terminal seat should be tightened to avoid burning the electricity meter due to bad contact and heating.
Wuhan TimeWave IOT technology Co., Ltd is a high-tech enterprise specializing in the application of Lora Wide Area Network (LoRaWan) core technology to realize the energy supervision service platform. Providing customers with one-stop overall solutions and services for metering communication equipment, software system platforms, project construction, and daily operation and maintenance management.
Based on the "TimeWave Cloud" energy regulatory platform, covering the measurement, meter reading, charging, management and control of hydropower, gas and heat. It can realize and provide automatic meter reading and charging, carbon emission monitoring, safe electricity consumption, energy consumption analysis, energy saving analysis, distribution and transformation monitoring, power environment monitoring of machine room, intelligent operation and maintenance and other subsystems. And we also independently developed and produced "TimeWave" LPWAN smart meter, intelligent water meter and communication terminal products. We have extensive experience in the practical application of water and electricity meters using Lorawan technology.
The "TimeWave Cloud" energy supervision platform has been widely used in campus, supermarket, apartment, hospital, factory, park, building, railway, airport, computer room and data center. It has been connected to iot Terminal 15W+, Project 200+, radiating 30+ provinces and cities in China, and provides operation and maintenance support for landing projects in Indonesia, Nigeria, Mongolia, Southeast Asia and other countries and regions.
We are committed to solving the problems of difficult meter reading, difficult charging, difficult payment, energy saving and efficiency, and safe energy use for you.
TimeWave aspires to become a leader in the field of energy IoT and energy supervision platform.
