Internet of Things valve controlled water meter power off and valve closing

When the water meter loses power, it will automatically close the valve to prevent accidental or human power outages; After powering on again, the valve returns to its pre power-off state.

Characteristics of IoT valve controlled water meter

1. The built-in low-power wireless data transmission module is designed with a fully digital integrated circuit, using LoRa spread spectrum debugging technology, which has the characteristics of anti-interference, long transmission distance, and low static power consumption. The static power consumption of the wireless remote water meter is less than 5uA, and the battery life of the water meter is over 6 years.

2. Equipped with battery undervoltage reminder, the wireless remote water meter uploads the battery voltage inside the water meter while transmitting the water meter reading. When there is a power shortage or undervoltage phenomenon in the wireless remote water meter, the meter reading system will automatically list the water meter as an abnormal water meter and remind the user;

3. It can achieve real-time communication and real-time control around the clock.

4. Equipped with valve control function, it can achieve two working modes: postpaid and prepaid;

5. The water meter has an identification code: water meter address;

6. The water meter automatically closes the valve when the battery is discharged or when the battery is dead;

7. The water meter can automatically close the valve when disturbed;

8. The water meter circuit board is treated with nano coating,.

9. The microprocessor adopts the MICROCHIP series Nava technology CMOS flash microcontroller from the United States, with a wide operating voltage and low power consumption. The internal EEPROM can be erased and written more than 100000 times;

10. Data retention and recovery function: In the event of a power outage, the data in the table can be saved for ten years. When powered on, it has the function of recovering data, and the data in the table is safe and sound;

11. Anti attack function: The sensor used in the water meter has the ability to resist magnetic attacks. Generally, external magnetic field interference will not affect the normal operation of the meter. At the same time, the management system can record and alert users of illegal attacks, improving the performance of the product;

12. The base meter adopts die cast copper one-time forming technology and is processed by CNC machine tools. It has high pressure resistance, no sand holes, and will not explode. It will not rust after long-term operation, has a long service life, good consistency in process design, B-level accuracy, accurate measurement, and stability;

13. The character wheel display is clear and easy to read, and the base table has a service life of ten years;

14. The ID number of the measuring instrument at the time of leaving the factory, and the establishment of complete production, debugging, use, and maintenance records.
