Photoelectric Direct Reading Remote Water Meter     

　　Hezhong Zhida photoelectric direct reading water meter uses photoelectric direct reading technology to directly read the digit wheel data. Compared with traditional pulse water meters, it reduces reading errors to zero, making it an electronic remote water meter with zero electromechanical conversion error in automatic meter reading systems. It features a low-power design, requiring no power supply during normal operation, and only needs power during meter reading.
