产品概述:

Photoelectric valve controlled water meter
Compared with the traditional pulse water meter, the photoelectric direct reading technology can reduce the reading error to zero. It is an electronic remote water meter with zero electromechanical conversion error in automatic meter reading system. It is a low power consumption, no power supply products. It only needs to supply power to the water meter when reading the meter.
Product features
1. Using advanced data coding and verification method, the communication reliability is high
2. It adopts rotating wing structure, high measurement accuracy, convenient meter reading and beautiful appearance. According to CJ / T 224-2012 standard.
3. The flow performance meets the standard of GB / t778.1 ~ 3 ~ 2007, and the accuracy level is 2
4. Compatible with a variety of communication specifications: DL / T645 / CJ / T188 and internal mode.
5. It meets the technical requirements of EMC / ESD / EM and other electronic products, and reaches the industry leading level
6. Combined with the host computer system, the remote meter reading management system is established, and the automation of meter reading monitoring is realized.
