Integrated gate valves are automated flow measurement devices that integrate measurement, real-time monitoring, and intelligent control. They serve as the fundamental support for irrigation area informatization. They can automatically collect various parameters during the measurement of hydraulic structures according to water measurement specifications, automatically judge the flow state, and calculate the gate flow based on the corresponding algorithm formula. They control the gate flow according to the settings and are equipped with supervisory software, achieving the allocation and adjustment of water distribution in irrigation channels, enhancing the informatization, intelligence, and remote management of irrigation areas. They achieve "visibility, transmission, control, and quantification" in agricultural irrigation.
