Photoelectric Direct Reading water meter

Using the new photoelectric direct reading coding technology, more accurate to read the mechanical position of the code data, there is no carry problem of character wheel 0 and 9. Using low-power design, no battery inside the meter, usually without power supply, only in the meter reading moment supply power, reading accuracy rate is 100%, is in the industry-leading level.


Product characteristics

Product characteristics
1. By encoding and decoding the number of rounds of the table “direct reading” out of the word on the digital position of the physical compiler;

2. Photoelectric direct reading module with automatic detection of each photoelectric component performance and reporting function;

3. The table has a unique identification code, ie the table address (factory number);

4. “0” power design, failure rate reduced, longer life;

5. Photoelectric direct reading module completely sealed in the counter, and water isolation, from outside water and moisture erosion;

6. Meet the “electronic remote meter” (CJ / T224-2012) standards;

7. The use of advanced data encoding and verification methods, communication reliability is high;

8. Compliant with EMC, ESD, EMI and other electronic products, electromagnetic compatibility aspects of technical requirements.
