Optical remote reading dry vertical water meter

Functional Features

 The optical remote reading water meter is a high-tech product independently developed by our company, with complete intellectual property rights. The product has obtained 5 patents and 2 software copyrights. The main technical features are as follows:

1. Wide product range: a domestic first Q₃/Q₁=160, can be made to 200 times if required by the user.

2. Advanced data encoding and verification technology is adopted, which can completely solve the 9-0 carry problem, ensuring high communication reliability.

3. The optical direct reading module completes encoding instantly when reading the meter, sending out data, with no deviation between the output number and the dial reading; shaking, backflow, and strong magnetic interference will not affect the meter reading.

4. Adopts a dry structure, completely isolating the electronic module from the external environment, unaffected by usage conditions; no liquid leakage, bubbles, or refraction effects, resulting in a lower failure rate.

5. Compatible with various communication protocols; DL/T645, CJ/T188, internal protocols, or other customer specifications.

6. Meets the design requirements for electromagnetic compatibility of electronic products such as EMC, ESD, EMI, reaching industry-leading levels.

7. Unique lightning protection design, bus pin ESD protection exceeds 10kv, RS-485 interface surge protection of 600W per line; protection against bus open circuit, short circuit, idle, and other faults.

8. Adopts low power consumption design, requiring power only when reading and switching the valve.

9. Combined with the upper computer system, establishes a remote automatic meter reading management system, truly achieving automation of meter reading and monitoring.
