Features of Photoelectric Direct-Read Water Meters
1. Accurate Reading: Real-time readings at any moment are consistent with the mechanical display of the water meter. No built-in or backup power supply is required, ensuring no data loss due to power outages or network failures.

2. Long Service Life: Utilizes photoelectric sensing technology for sampling, with no mechanical contact or movement, making it immune to failures caused by vibrations from pipelines or other factors.

3. Strong Anti-Interference Capability: Contains no magnetic components, ensuring no interference from ferromagnetic materials or vibrations caused by pipelines or other factors.

4. Safe to Use: The meter employs low-voltage circuits for communication. High-voltage power sources are physically isolated from the water meter, with high insulation strength ensuring safety.

5. Easy Installation: The base meter of the direct-read water meter shares the same installation specifications as ordinary mechanical water meters, making installation straightforward.

6. Reliable Valve Switching: Internally uses a waterproof gear reducer with a 3500:1 reduction ratio and all-metal gears, providing high torque and reliability. It can open and close valves normally under 1.0 MPa water pressure, avoiding valve switching failures caused by scaling in ball valves (common in valve-controlled water meters).

Advantages Compared to Traditional Card-Based Meters

1. Eliminates the difficulty of door-to-door meter reading and reduces the need for numerous meter readers. Addresses issues with IC card management, such as multiple card vending software, counterfeit cards, and fake cards, simplifying management. Key advantage: "Remote Meter Reading."

2. Solves inaccurate meter reading issues. Key advantage: "Direct Reading."

3. Resolves complex wiring problems. Key advantage: "M-BUS Wiring."

4. Eliminates the need for 24-hour power supply, data loss after power outages, and short backup battery life. Key advantage: "No Power Supply Required for the Meter."

5. Reduces the number of data collectors and maintenance workload, and eliminates the need for external power supply. Key advantage: "Manual Centralized Meter Reading Without External Power Supply."
