Calinmeter is a leading provider of STS smart prepayment metering solutions in China. As the 47^th member of the STS Association (STSA), we are one of a select group of Chinese manufacturers capable of developing both meter hardware and the associated software. Notably, we are the only manufacturer in China to have applied STS technology to a range of utility meters, including electricity, water and gas meters. With over a decade of experience in STS metering, the main body of Calinmeter's meters is manufactured using the finest techniques, a quality proven by over 10,000,000 installations worldwide.

The CA768 is a successful adaptation of STS electric meters for gas metering. This meter features LoRaWAN connectivity, enabling Advanced Metering Infrastructure (AMI) and remote automatic meter reading (AMR). Users can conveniently use a 20-digit token code to top up their gas supply. The meter supports both prepaid and postpaid operational modes. Boasting an impressive battery life of up to seven years, it incorporates an anti-tamper valve shut-off mechanism. Optional gas leakage detection sensors can be added. The integrated LoRaWAN module from Semtech facilitates straightforward AMR/AMI smart metering setup. Low credit and low battery status are also indicated.
