The flow measurement pod integrates a radar flowmeter, a non-contact water level meter, and a fixed-focus camera. It uses non-contact measurement and is not affected by sediment, aquatic plants, and other debris. The embedded algorithm model ensures accurate, stable and reliable flow measurement. The pod adopts professional two-axis mechanical stabilization technology with a stabilization accuracy of ±0.01°. It supports connection with unmanned aircraft through a quick-release interface and can be applied in multiple industries such as hydrology, flood control and drainage, and environmental pollution discharge monitoring.
