This water meter, through an integrated and innovative approach, adds measurement functions for water quality (including turbidity, residual chlorine, and pH value), water pressure, water temperature, etc., on the basis of water metering. It can be directly installed under pressure on the water supply network, and after water quality measurement, the tested water sample can automatically flow into the water supply pipeline. This product can perform real-time dynamic monitoring of domestic water and is suitable for application scenarios such as treated water from centralized water supply, terminal water in pipe networks, and secondary water supply. It provides real-time information for water supply enterprises in calibrating pipe network hydraulic models and acquiring key data, assisting enterprises in the refined construction of pipe networks.
