The CZI MF30-M4 is a precision hydrological measurement payload for the DJI Matrice 4 Series, combining a 24GHz surface velocity radar and 80GHz ranging radar (±2mm accuracy) in a 108g PSDK-integrated sensor. Deployable by a single operator in under two minutes, the MF30-M4 delivers professional-grade flow measurement with CZI Pilot software, automated route missions, and cloud-synchronized data management.

Dual Radar. ±2mm Accuracy. Professional Hydrology from the Air.
24GHz velocity radar measures surface flow from 0.1 to 20 m/s 80GHz ranging radar delivers ±2mm water surface distance accuracy 108g PSDK payload for DJI Matrice 4 Series (M4E, M4T, M4D, M4TD) Single operator setup and deployment in under two minutes CZI Pilot software: measurement, flow calculation, and data export Automated route-based missions record all measurement point data Supports Area-Velocity, International, and Liwen calculation methods Cloud sync with visualized hydrological data management IP55 rated for field deployment in light to moderate rain

Non-Contact Flow Measurement. No Wading Required.

The MF30-M4 measures water surface velocity and distance from the air — eliminating the need for personnel to enter waterways. Ideal for flood response, post-storm assessment, and routine hydrological monitoring where access is dangerous or impractical.

CZI Pilot Software. Automated Missions. Cloud Data.

CZI Pilot handles the full workflow — from automated route-based flight missions that record every measurement point, to flow calculation using Area-Velocity, International, or Liwen methods, to cloud-synchronized visualization and reporting for regulatory submission.

108g. PSDK Native. Deployed in Under 2 Minutes.

At just 108g, the MF30-M4 mounts natively to the DJI Matrice 4 Series via PSDK with minimal impact on flight performance. A single operator can have the system airborne and measuring in under two minutes — critical for time-sensitive flood and emergency response operations.

24GHz + 80GHz Dual Radar. ±2mm Accuracy. Hydrological Data from the Air.

The CZI Drone Flow Meter is a precision hydrological measurement payload engineered for the DJI Matrice 4 Series and Matrice 30 Series via PSDK integration. Combining a 24GHz surface velocity radar (0.1–20 m/s range) with an 80GHz ranging radar (±2mm water surface distance accuracy), the MF30 delivers professional-grade flow measurement from a lightweight drone-mounted sensor — deployable by a single operator in under two minutes. CZI Pilot software handles measurement, flow calculation, and data export, with support for Area-Velocity, International, and Liwen calculation methods and cloud-synchronized hydrological data management.
