A highlight of the visit is the next-generation smart gas meter, equipped with an embedded microcontroller and sensor array that intelligently detects leakage scenarios and automatically shuts off the gas supply under three critical conditions: a continuous ultra-low flow over 24 hours (typically indicating a pinhole leak), a sudden surge in flow (indicating a dislodged gas pipe), or an extended period without scheduled on-site inspection � ensuring uncompromising safety for every household.
