KEFD
Designed specifically for non-residential user
trade settlement and community DMA applications in water supply enterprises, this product is characterized by a high range ratio (R160, R250, R400, R500), an extremely low starting flowrate (5 mm/s),a long battery life (up to 10 years of usage), and a high protection level(IP68). It is well-suited for various harsh environments and
assists water companies in reducing the production-sales differ-encewhileprovidingdatasupportto control leakagerates.
