Smart Electric Energy Meter: Single & Three Phase, Lorawan/RS485/4G with Prepaid Remote Control and Ami/AMR Solution
The intelligent electricity meter has the functions of electric energy measurement, power parameter measurement, time-sharing measurement, real-time freezing, on-off control, LoRaWAN and RS485 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.
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.

LoRaWAN Smart Electric Meter: The Future of Electric Management
LoRaWAN (Long Range Wide Area Network) Smart Electric Meters bring
several key features to the table, largely due to the specific
advantages of the LoRaWAN communication technology itself. Here are
some key features:
Long-Range Communication: LoRaWAN has a range of up to 15 kilometers in rural areas, and up
to 5 kilometers in urban areas. This makes it perfect for smart
meters, especially in areas where meters are spread out over large
distances.
Low Power Consumption: LoRaWAN devices consume very little power, which means the smart
meters can operate for years without needing a battery replacement.
This is crucial in remote areas where regular maintenance may be
impractical.
High Capacity: A single LoRaWAN gateway can handle up to thousands of nodes,
meaning that a single gateway can receive data from thousands of
smart electric meters, making it a cost-effective solution for
large scale deployments.
Security: LoRaWAN uses two layers of encryption (unique network,
application, and device keys) to ensure that the data being
transmitted is secure. This is important in smart meters where
privacy and security are key concerns.
Adaptability: LoRaWAN's Adaptive Data Rate (ADR) feature optimizes data rate,
airtime, and energy consumption, making it suitable for varying
network conditions.
Bi-Directional Communication: Unlike some other technologies, LoRaWAN allows for both uplink
(device to server) and downlink (server to device) communications.
This enables not just data collection, but also remote control or
firmware updates if necessary.
Geolocation: LoRaWAN enables geolocation without additional power consumption,
which can be beneficial in certain metering or grid applications.
Interoperability: LoRaWAN is based on open standards, which allows devices from
different manufacturers to work together seamlessly. This is
crucial for utilities companies who might have meters from
different vendors.
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.
