The electricity meter is a instrument used for electric energy metering and billing. As technology rapidly increases and the information age expands, the market demand for the function of energy metershas increased, from a single metering function to communication,tariff, event alarm, load profile, load control, anti-tamper, prepayment, etc. The prepaid meter in the mode of paying first and then using electricity effectively solves the problem of charging difficulty, and has been widely used in the market.

Over time, the function of prepaid meters has become increasingly abundant, and it has developed into Smart prepaid meters. Yongtailong’s D124065 STS standard prepaid meter is very popular in the African market.
