In recent years, refined global certification codes have prompted tighter import regulations for smart meters worldwide, pushing the whole industry to focus on compliance-oriented R&D. Manufacturers optimize product structure and production technology to enhance durability and measuring accuracy in line with authoritative certifications such as KEMA and ISO, satisfying procurement specifications from utility operators globally. As power market reform advances in emerging regions, local power suppliers phase out outdated mechanical meters in favor of new-generation smart devices featuring remote data transmission and prepayment control. Backed by complete certification credentials, qualified metering products overcome geographical and policy hurdles to participate in global grid renovation, enabling visualized power data and centralized grid maintenance and boosting coordinated development of the whole smart energy industrial chain.
