Calinmeter is a leading provider of STS smart prepayment metering solutions in China. As the 47th member of the STS Association, Calin boasts over a decade of experience in STS metering technology. The CA768 represents a successful adaptation of STS principles from electric meters to gas meters. Its base meter is meticulously designed to accurately measure volumes of various gases, including natural gas, town gas, and liquefied petroleum gas. Simultaneously, an STS-compliant electronic control unit is integrated, serving as an effective revenue protection mechanism.

Calin's STS gas meters are supplied to numerous countries and regions, including Iraq, Pakistan, Indonesia, Mexico, Kenya, Tanzania, and many others.

Furthermore, Calin gas meters can communicate wirelessly with a Customer Interface Unit (CIU) keypad. The CIU is installed within the customer's premises at the time of meter installation and is securely locked. Customers utilize the CIU to conveniently check their remaining balance, view top-up history, and most importantly, remotely input recharge token codes to replenish their gas supply.
