MA602/MA602B Smart Diaphragm AMR Gas Meter

MA602/MA602B Smart Gas meter is based on High-reliable traditional diaphragm meter. It supports both pre-payment & post-payment mode with motor valve embedded. MA602B adopts normal AA size battery to enable customer to change the battery by themselves to achieve low battery cost. While MA602 uses lithium battery to make convenience for customers’ one time use without any maintenance. . KAIFA's excellent design makes its power consumption very low, extending battery life time. Anti-tamper system is configured to protect metrological function. The AMR solution is KAIFA's own LoRa network with a time-tested total solution, realizing reliable connection experience.
