WiFi Single Phase Smart Electric Energy Meter with Prepaid Remote Control and Electricity on-off Control, Time-Based Billing
The intelligent electricity meter has the functions of electric energy measurement, power parameter measurement, time-sharing measurement, real-time freezing, on-off control, WiFi communication etc. It has the advantages of long communication distance, large capacity, fast and convenient installation, and long service life.
Our Advantages
1.Measure Forward and Reverse Active Energy: 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.

Display Description
LCD full-screen display schematic diagram (as shown above)
The specific display items are listed as follows:
Status indicator lamp:
The electricity meter uses a bright, long-life LED as a pulse
indicator light.
It has active power pulse indicator light: red, usually go out,
flashing when measuring active power.
LoRaWAN/Bluetooth/RS485/Cat.1 Module status indicator: green. Always on indicates online,
and flashing indicates going online.
Note
INSTALLTION
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.
TRANSPORTATION AND STORAGE
Ammeters must be transported and stored under the original
packaging conditions. Products shall not be severely impacted
during transportation and unpacking, and shall be transported and
stored according to GB / T 25480-2010 Basic Environmental
Conditions for Instrument Transportation and Storage and Test
Methods as stipulated in 2010. The products should be stored in the
warehouse and placed on the platform frame. The stacking height
shall not exceed five layers. No corrosive gases shall be present
in the stored environment.
WARRANTY PERIOD AND AFTER-SALES SERVICE
If the user complies with the transportation, storage and
installation operation specifications, and the lead seal of the
manufacturer is still complete.If there is a quality problem, our
company is responsible for free repair or replacement within 18
months from the date of delivery the electricity meter.
During the whole life cycle of the products, our company implements
"three guarantees" for all electricity meter products, providing
necessary maintenance and services. Providing equipment wiring
diagram and necessary technical documents and drawings. According
to the requirements of users, provide necessary training for
maintenance personnel and operators. Providing training materials,
and update the software regularly and provide free upgrade.
After receiving the service request of the product user, our
company will respond within 12 hours.
