LORA wireless remote water meter reading is a wireless remote centralized meter reading method that has undergone many years of development. With the continuous improvement of core technology, Huiyi has summarized years of practical experience and explored advanced technologies. Based on the requirements of power consumption, transmission distance, anti-interference, and other aspects of wireless meter reading for water meters, the advanced LORA spread spectrum modulation wireless transmission technology is adopted. At the same time, combined with years of application experience in the water meter industry, a strong and reliable wireless meter reading transmission protocol is designed, forming an intelligent LORA wireless remote water meter system with high reliability, easy system expansion, simple installation and maintenance, and high success rate of meter reading.

【 LORA Wireless Remote Water Meter Features 】

1. The system adopts TDMA time-division address communication method and automatically synchronizes communication time units; Frequency modulation technology avoids co frequency interference and improves transmission reliability. The adaptive algorithm for transmission rate and distance effectively increases system capacity.

2. The wireless remote water meter system integrates collection and measurement, two-way traffic, and meter reading valve control. The system includes a wireless remote water meter, concentrator, handheld device (supplementary reading), and meter reading system.

3. The system is suitable for remote meter reading and control of civil water meters in various building structures such as multi story and high-rise slab buildings, towers, villas, apartments, etc.

4. The system is based on LORA communication technology and adopts a simple star shaped network structure, with low communication delay, long and reliable transmission distance.

5. Adjacent communities can share concentrators, expand wireless transmission distance without the need for repeaters, reduce system costs, and improve meter reading success rates. The concentrator can manage 5000 water meters.

6. The water meter has three working modes: LOP1，LOP2，LOP3， Response time: 12s, 24h-12s, 24h; ER18505 battery design service life: 6 years, 8 years, 10 years. Customers can switch between any working mode through the concentrator during actual use. Automatically maintain valves every month.

7. No complex construction wiring scheme is required, with a small amount of work. The concentrator and water meter form a star shaped network, and the concentrator is connected to the backend server through GRPS/4G to form a stable and reliable network structure. At the same time, all water meters and concentrators adopt independent core technologies such as multi frequency, multi rate, and anti-interference to avoid problems such as inaccurate and unstable meter readings, ensuring long-term stable operation of the system and significantly reducing maintenance costs in the later stage.

8. Including metering, anti magnetic, power supply voltage detection, metering value power-off storage function, valve in place development status detection, valve control circuit, and automatic unblocking valve.

9. The table stores 5000 transaction records and frozen monthly data for 10 years and 12 months.

10. Proactive data reporting mode: Proactively report meter reading data once every 24 hours.

The warranty period for LORA wireless remote water meter from Anhui Dingzheng Electric Co., Ltd. is six years
