What is an STS Gas Meter?

I. Introduction to STS Gas Meters

The STS prepaid gas meter is a prepaid gas meter solution that complies with the STS protocol. Users can recharge the meter and query parameters by entering a 20-digit recharge code or a 2-digit query code through the touch buttons integrated on the meter. In addition, the meter has a reserved infrared communication method, and users can also use an infrared remote control to input recharge/query codes, which is suitable for users whose meter installation locations are relatively concealed and inconvenient to access.
