Products Description
VIEWSHINE Old Brass Water Meter stands out with its excellent technology and reliable quality. The unique three wire pulse output communication function, combined with advanced wireless communication and data analysis technology, ensures accurate and timely data transmission. Innovative engineering plastic structure and zero moving parts ultrasonic sensing system, achieving a 12 year ultra long service life, and maintaining a stable measurement accuracy of ± 1% throughout the entire service life, without maintenance, worry free and labor-saving. The combination of LoRaWAN/NB IoT dual-mode transmission and machine learning water analysis engine greatly improves the efficiency of water billing and management, effectively reducing costs. It can also accurately monitor water waste and leakage issues, helping users use water reasonably. The powerful pressure resistance of 16 bar, as well as multiple authoritative certifications such as MID B+D, OIML, WRAS, etc., fully demonstrate its excellent quality and make it a reliable choice for smart water meters.
