Smart Water Flow Meter with Prepaid Remote Control and Lora/Lorawan/4G, Cold/Hot Flowmeter, DN15/DN20/DN25
The Smart Water Meter of the Internet of Things is composed of Dry Water Meter base meter, Electric Ball Valve, Magnetic Resistance Sensor, MCU, Lithium Sub-battery Pack, LoRaWAN Wireless Communication Module, Control Circuit and other components. It adopts the Electromechanical Separation structure design. It has the advantages of long communication distance, large capacity, fast and convenient installation, and long service life.
Our Advantages
1. Split Structure: The electronic units are relatively independent of the base table.
2. Accurate Measurement: Using non-contact electronic detection logic and measurement
accuracy of 10 liters to ensure the mechanical and electrical
consistency.
3. Physical buttons: Touch button wake-up and long press on the button to immediately
go online remote data transmission.
4. Infrared Communication Interface: Can read and set relevant parameters.
5. Alarm Functions: Abnormal state, measurement fault, abnormal battery voltage,
abnormal valve, etc.
6. Timing Uploading Function: Automatically upload data at set time points (once a day by
default), and also receive and execute valid instructions from the
platform.
7. Micro-power Consumption Design: Adopt 3.6V lithium sub-battery pack (ER26500 + HPC1520), with
dormant current <10uA.
8. Clock Calibration Function: Automatic calibration function and remote calibration function of
platform after the water meter is connected to the network.

LoRaWAN Smart Water Meter: The Future of Water Management
Our LoRaWAN Smart Water Meter represents a leap forward in water
management technology. This state-of-the-art device combines the
groundbreaking LoRaWAN protocol with advanced metering technology
to deliver real-time, secure, and accurate water usage data.
Long-Range Communication: Our device uses LoRaWAN, a low-power, wide-area network protocol,
designed to communicate over several kilometers in rural areas and
several hundred meters in urban settings. This ensures reliable
data transmission, no matter where your meter is located.
Low Power Consumption: The Smart Water Meter operates with minimal power, making it
ideal for locations where electricity supply may be unreliable.
Thanks to this feature, the meter can run for years on its battery
before requiring a replacement.
Real-Time Data Monitoring: Stay informed about your water usage with real-time data updates.
Our smart water meter helps you identify leaks, conserve water, and
manage your water usage more efficiently.
Secure Data Transmission: Your data's security is our top priority. That's why our smart
water meter uses AES-128 encryption, ensuring your data remains
safe and confidential.
Scalability: With the ability to support millions of devices, the LoRaWAN
Smart Water Meter can be deployed across wide areas. This makes it
an ideal choice for both individual and commercial usage.
Geolocation Capabilities: Our smart water meter offers geolocation data, helping you easily
locate your meter or detect any unauthorized movement.
Bi-Directional Communication: Not only can the smart water meter send data to the network, but
it can also receive important information, such as firmware updates
or specific commands, ensuring your device is always up-to-date and
functioning optimally.
Embrace the future of water management today with our LoRaWAN Smart
Water Meter. It's not just a product; it's a solution for
efficient, secure, and intelligent water management.
Display Description
Under the normal state, the water meter will be automatically put online once a day (settable). Through wireless communication, the water meter data will be uploaded to the system platform, and the relevant instructions of the system platform (parameter setting and valve control, etc.) will be received and executed at the same time.
In order to prevent human malicious multiple triggers to go online (loss of battery power), we specifically set the interval time between two consecutive trigger line must be more than 5 minutes. And it is stipulated that the number of daily button trigger on the line should less than 8 times (the infrared communication setting instruction is not affected by the number).
When the valve is closed, long press and hold the trigger button for the first time every month for 3 seconds, and the water meter valve will open. The water meter valve will be opened to overdraft using 3m³ water. When the overdrawn 3m³ water quantity is used up, the water meter closes the valve automatically.

Note
l. Water meters should be checked frequently to prevent water meter
leakage accidents.
lI. In winter, it is necessary to prevent the water meter from
freezing and bursting. Installing insulation measures to the water
meter when necessary.
lII. When the home is not occupied for a long time, should close
the valve in front of the table to prevent water leakage accidents.
lV. Water meter is a measuring product and shall not be destroyed.
Destroying water meter is an illegal action.
