Features of Smart Lora Water Meter
1. But real-time communication, copy control in real time.
2. With valve control function, it can realize two working modes of post-paid and pre-paid.
3. The water meter has a unique identification code, the water meter address.
4. When the water meter receives interference, it will automatically close the valve.
5. Water meter circuit adopts waterproof treatment, waterproof and moisture-proof.
6. In the case of power failure, the data in the table can be stored for ten years. When power is on, it has the function of restoring data to ensure that the data in the table is safe.
Lora water meter parts and connectors are made of non-toxic and pollution-free high-quality materials that meet the requirements of water quality and sanitation conditions. They are resistant to water and atmospheric corrosion, have a reliable anti-corrosion layer, and all internal circuits are sealed with epoxy resin.
1. Wireless remote water meter introduction
Measurement:
1) Electromechanical separation design: The magnetic induction and acquisition technology is adopted, and the mechanical part and the electrical part are separated to avoid the influence between the water circuit and the circuit.
2) Coded sampling technology: According to the collected measurement signal sequence, the direction of water flow can be identified, and the miscalculation caused by water pressure instability, impeller jitter and backwater is solved, and the measurement is more accurate.
2. Information inquiry
1) The management system or mobile phone can query the water consumption, water meter status, signal strength and other information at any time.
2) The water meter is designed with liquid crystal display. In addition to querying relevant information in the management system or mobile phone, the relevant information can also be queried on site.
3. Active reporting and call response dual communication mechanism
1) Timing report: The wireless water meter periodically reports the water information and water meter working status. This mechanism can greatly save the power consumption of the wireless water meter.
2) The alarm information is automatically reported: the alarm message is immediately reported by the magnetic attack, the battery is under voltage or the battery is destroyed, and the alarm information is immediately reported.
3) Calling response: The system actively calls the water meter data and status, and can remotely control the water meter valve in real time to ensure the timeliness of response.
Due to the dual mechanism, it takes into account the advantages of real-time, low power consumption, real-time measurement and control.
4. Protection design
Fault alarm
Water meter battery undervoltage, battery is destroyed, cut off immediately alarm; water meter is magnetically dry
The disturbance and magnetic attack immediately alarm.
5.LoRa signal reliability
1) Adopt time division multiplexing + automatic avoidance mechanism. Avoid channel congestion and channel interference.
2) Professional circuit design, strong noise suppression; select materials, select high-precision, low-temperature drift devices to prevent electrical performance degradation over time and environmental changes.
3) Solve the wireless frequency offset problem and have strong fault tolerance.
6. Environmental adaptability
Waterproof and moisture proof design
With special potting material and special potting technology, the water is expressed in IP68 protection level and can be installed in almost any environment. The potting material is invariable at -30°C-70°C, does not crack, and does not become brittle. It fully satisfies the installation in water immersion and high humidity environment.
7. Anti-rust function
The water meter valve automatically switches every half month to prevent the valve from rusting.
8. Service life
1). The base case is made of copper shell, stainless steel ball valve, and the remote part is made of ABS plastic case. The electronic part is potted with special technology. The waterproof level is in accordance with the IP protection standard of the IP code standard, which ensures the water meter meets the service life requirement.
2). The remote water meter has a data storage function, and the power-down data is not lost.
3). Low power design
