overview
Viewshine's city water meters have significantly improved overall water resource management efficiency by optimizing non revenue water and utility benefits. This water meter adopts innovative design and has a service life of 12 years, surpassing traditional mechanical water meters. Its non moving parts ensure always accurate readings while requiring minimal maintenance. In addition, due to the use of high-quality engineering plastics known for their excellent strength and pressure resistance, its maximum allowable pressure (MAP) is 16 bar.
