Overview

Introduction: The photoelectric direct reading valve controlled water meter adopts photoelectric direct reading technology to read character wheel data. Compared with traditional pulse meters, it can reduce the reading error to zero. It is an electronic remote water meter with zero electromechanical conversion error in automatic meter reading systems, and adopts a low-power design. It usually does not require power supply and only needs to be powered during meter reading or valve operation.
