Water River flow rate volume and water level measurement sensor for DJI M350

Description

The DJI M350 drone river water flow measurement sensor is a flood early warning system that integrates both flow velocity and water level radar. It is capable of simultaneously detecting river flow speed and water level rise. Using intelligent pre-planning software, it can calculate flood season flow rates, providing multifunctional support for hydrological inspections and flood early warning applications. Featuring excellent waterproof and dustproof performance, it operates reliably in harsh weather conditions. The device is equipped with a DJI Skyport V2.0 interface, allowing seamless mounting on DJI M300 and M350 RTK series drones.

Key Features:

• Integrated Flow Velocity and Water Level Radar
  Compact and highly accurate, the system effectively filters out noise interference and meets the high-precision detection requirements of water resource management.

• Advanced Heat Dissipation, Waterproof and Dustproof
  Designed with superior heat dissipation and waterproof capabilities, it supports operation in moderate rain conditions. The system has a protection rating of up to IP5X.

• Comprehensive Flow Measurement Capabilities
  Measures water flow velocity and water level while calculating river discharge. Supports simultaneous detection of river flow speed and water level data. With intelligent software, it can analyze flood season discharge and automatically generate reports.

• Seamless DJI SKYPORT V2.0 Integration
  DJI SDK Payload, equipped with a non-destructive quick-installation rotating buckle, ensuring seamless compatibility with the DJI M300 M350 series flight platform.

Measurement Principle:

The DJI M350 river flow rate measurement sensor utilizes the Doppler shift principle to measure water surface flow velocity. In the field of acoustics, when a sound source and a receiver (i.e., the probe and the reflecting surface) are in relative motion, the frequency of the reflected signal changes. This frequency variation is known as the Doppler effect.

When the sensor moves relative to the water surface at a velocity V, the frequency of the electromagnetic waves received by the radar differs from the frequency of the emitted waves. This frequency difference is called the Doppler shift. By calculating the relationship between Doppler shift and V, the water surface flow velocity can be determined.
