Qinchuan patent (CN101894421A) models WL-G1.6, WL-G2.5, WL-G4, WL-G6, WL-G10,WL-G16, WL-G25, WL-G40 are remotely controlled intelligent gas meters which based on IC card intelligent gas meters electronic and mechanical techniques, improved with telecommunication technology to achieve electronic metering, remotely valve control, remotely prepayment and management of the meters.
Qinchuan remotely controlled intelligent gas meter adopts to LoRa technology, integrate with low power consumption and big data communication technology, its built-in France brand SAFT battery life span is minimum thirteen years.
Valve is the most important component of intelligent gas meter which determines intelligent gas meter's quality and reliability. Qinchuan patent (CN101907194B) on bidirectional blockage-free gear-driven special electro-mechanical valve for gas meter, a special design on valve which solve the locked-rotor current problem of worm drive valve, minimize the open/close valve current to 40mA, limit the internal leakage of meter less than 10mL. All these parameters are highly superior of the international standards.
