Product Introduction
Product Brief
The photoelectric direct reading water meter adopts photoelectric direct reading technology to read the character wheel data. Compared with traditional pulse meters, it can reduce the reading error to zero and is an electronic remote water meter with zero error in electromechanical conversion in automatic meter reading systems. The photoelectric direct reading water meter, combined with the intelligent meter reading system equipment, completes the intelligent reading of water, electricity, and gas meter data in the community, and realizes data sharing with the settlement center through networking.
