Photoelectric Direct-reading Wired Remote Water Meter uses electronic remote transmission technology to directly read character wheel data.
FeaturesIndustrial, Agricultural, Bulk
Compared with conventional pulse water meters, it can reduce reading errors to zero, making it an electronic remote transmission water meters with zero error in electromechanical conversion in automatic meter reading systems. Moreover, it adopts a low-power design, requiring no power supply normally and only needing power supply during meter reading.
