Direct-reading Valve Control module uses photoelectric direct reading technology to read data word round, compared with the conventional pulse table, it can be reduced to zero reading error, AMR metering system is ideal zero error product. Module uses low-power design, usually no power supply, only when the meter readings and conduct valve switch its power needs. The module can be installed directly in the base table counter, assembled into remote base table VRLA photoelectric direct reading table, with the smart metering system equipment, complete intelligent reading copy cell data and remote meter control valve on / off, and Implementation and settlement center networking data sharing.
