MA603-X-S Serial smart gas meter is based on a High-reliable traditional diaphragm meter with KAIFA’s abundant experience in AMI system. Index is designed with standard interface to base meter variants for G1.6, G2.5,G4 household meter, and also for G6,G10,G25,G40 commercial meter.
Long term battery solution is supported for 20 years, there are both battery positions inside meter box, one is only for metrology function, another is for communication as primary battery, which has separated sealing protection, and supported to be replaced without losing measurement.
Flexible communication solution is supported, and could be replaced on site without power off meter. KAIFA could support LoRaWan, Sigfox, NB, Mbus and GPRS so far. And also do will provide customized design as customer requirement.
