Unmanned Aerial Vehicle Flow Measurement System

UAV RADAR

The unmanned aircraft is equipped with radar sensors for measuring water flow speed.

Key Feature

Flow measurement probe to ensure accurate and reliable data
Quickly and accurately measure the surface flow velocity of water bodies.
Simple and sequential operation process
Convenient and quick transportation and movement
Can achieve synchronous viewing of multiple data ends
Automatically process and analyze measurement data
Can be completed in blocks multiple times to ensure data integrity

The flow-measuring unmanned aerial vehicle is a scientific instrument and equipment that conducts hydrological monitoring by carrying out sensors such as radars. It is mainly used for emergency hydrological monitoring and the monitoring of river flow velocity during heavy rain and floods. It has the ability of non-contact measurement and can remotely and in real-time detect water conditions and transmit high-definition images, effectively overcoming the safety risks and terrain limitations of traditional flow measurement methods.

The flow measurement unmanned aerial vehicle system usually consists of an unmanned aerial vehicle platform, a ground station and a software platform. It has functions such as intelligent flight path planning and automatic return to base, and is suitable for complex scenarios such as dangerous terrain and flow velocity detection at breach sites.
