Wired photoelectric direct reading remote water meter

Xuxinda photoelectric direct reading module adopts photoelectric direct reading technology to directly read the character wheel data. Compared with the traditional pulse water meter, it can reduce the reading error to zero. It is an electronic remote meter with zero error of electromechanical conversion in the automatic meter reading system. . And it adopts a low-power design, usually without power supply, it is only necessary to supply power when reading the meter.
