WTM electromagnetic water meter

DN40-300mm
electromagnetic water meter is specially designed for the water industry to meet the needs of urban water supply and water resources management systems. It is suitable for water metering and DMA zone metering for large customers, and provides a large amount of stored data to ensure accurate trade settlement. It is widely used in areas without power supply on site. Places such as urban water supply, sewage treatment, water conservancy projects, etc.
