In the realm of modern urban infrastructure, the water supply network stands as a cornerstone. Its seamless and secure operation is the bedrock for sustaining the quality of life of residents and fueling social and economic progress. At the heart of this network, flow meters emerge as essential instruments, with the prime task of precisely gauging the water volume coursing through pipelines. Among the diverse array of flow meter types, insertion flow meters and pipeline flow meters have carved a niche for themselves in the water supply sector, courtesy of their distinct advantages. **Insertion Flow Meters: A Closer Look** - **Keywords**: Insertion Flow Meter, Structure, Point Flow Type, Runoff Type, Faraday's Law, Electromagnetic Induction, Conductive Medium, Magnetic Field, Induced Voltage, Electrodes, Stability, Reliability, Compact Design, No Moving Parts, No Flow Obstruction, Physical Parameter Independence, Petroleum, Chemical, Metallurgy, Power, Papermaking, Food, Water Trea
