    Product use

    Photoelectric direct-reading valve control water meter uses optical direct reading technology to read the wheel data, compared with the traditional pulse table, it can reduce the reading error to zero, automatic meter reading system is zero-error electromechanical conversion electronic remote meter, And the use of low-power design, usually without power supply, only meter reading or valve when it needs to be powered.


    PRODUCT FEATURES



    This series of remote water meter for the dry structure.

    Convenient reading, long-term clarity.

    Optical encoding passive direct reading technology.

    Valve can control water.
