CZI MF30-M4 Drone Flow Meter

CZI MF30-M4 Drone Flow Meter: UAV-Integrated Surface Velocity and Flow Measurement Payload for Enterprise DJI Matrice 4 Series Programs The CZI MF30-M4 is a compact drone-mounted flow meter payload built for rapid surface water velocity measurement, reference water level calculation, and cross-section flow computation on the DJI Matrice 4 Series. Developed by CZI for emergency hydrological monitoring and enterprise water resource management programs, it integrates a 24GHz velocity radar and an 80GHz ranging radar into a single 108g PSDK payload that a single operator can install and deploy in under two minutes. For fleet programs running flood emergency response, routine hydrological surveys, or infrastructure monitoring operations, the MF30-M4 provides a fast, repeatable aerial measurement capability that eliminates the logistical complexity of ground-based flow measurement equipment in hazardous or inaccessible environments. The 24GHz velocity radar measures surface flow speeds from 0.1 to 20 m/s with accuracy of ±0.01 m/s at speeds below 1 m/s and ≤±1% full scale at speeds above 1 m/s, at a recommended operating altitude of 1 to 10m above the water surface. The 80GHz ranging radar measures water surface distance from 0.18 to 30m with ±2mm ranging accuracy, providing the real-time distance data needed to calculate reference water levels against established benchmarks. The full CZI Pilot software pipeline runs on the drone controller and covers automated waypoint and route-based flight missions, river cross-section data import, flow calculation using Area-Velocity, International, and Liwen methods, coefficient calibration, cloud data synchronization, and tabular data export — consolidating the entire measurement workflow into a single deployable system. CZI MF30-M4 Mission-Ready Capabilities 24GHz velocity radar: measures surface flow from 0.1 to 20 m/s with ±0.01 m/s accuracy. 80GHz ranging radar: water surface distance measurement from 0.18 to 30m at ±2mm accuracy. Lightweight build: 108g payload connects to DJI Matrice 4 Series via PSDK for fleet deployment. Two-minute deployment: single operator installs and deploys the payload without tools or ground support. CZI Pilot integration: complete flow monitoring pipeline from measurement to calculation and export. Automated flight missions: route-based automatic flight records all measurement point data across programs. Reference water level: Pearl River, Wusong, and other benchmark calculation systems supported. Flow calculation: Area-Velocity, International, and Liwen methods for cross-section flow computation. Cloud synchronization: flow data syncs to cloud platform for visualized hydrological data management. IP55 rated: sealed against dust and water jets for sustained deployment in light to moderate rain. Applications and Use Cases Flood emergency response: rapidly measure breach flow velocity at river upstream points during flood events, giving response teams actionable hydrological data within minutes of arrival without ground-based equipment. Routine hydrological surveys: import river cross-section data and conduct scheduled surface velocity measurements at fixed monitoring points to support ongoing water resource management and fleet reporting programs. River cross-section flow calculation: combine measured velocity data with imported cross-section profiles to compute volumetric flow rates using Area-Velocity, International, or Liwen calculation methods across multiple survey points. Water level monitoring: use the 80GHz ranging radar alongside RTK elevation data to calculate reference water levels relative to established benchmarks such as Pearl River or Wusong datum for compliance and reporting. Disaster reconnaissance: deploy rapidly over inaccessible or hazardous waterways during disaster events to collect flow and water level data that ground teams cannot safely reach, supporting incident command decisions. Dam and reservoir management: conduct scheduled flow measurements upstream and downstream of dams and reservoirs to support discharge management, spillway operations, and long-term safety monitoring programs. Irrigation and agriculture water management: measure flow rates in irrigation channels and agricultural water supply systems to support allocation decisions, efficiency monitoring, and seasonal water management programs. Environmental monitoring: collect surface velocity and water level data in rivers and wetlands for ecological research, habitat assessment, and environmental compliance reporting across multi-site monitoring programs. Urban stormwater management: measure flow velocity in urban drainage channels and stormwater systems during and after heavy rain events to support drainage capacity analysis and municipal flood risk assessment. Bridge and infrastructure inspection support: measure flow conditions near bridge piers, culverts, and hydraulic structures to assess scour risk and provide hydrological data for infrastructure safety evaluations. The CZI MF30-M4 addresses a core operational gap in enterprise water resource and emergency response programs: reliable, repeatable aerial flow measurement from a platform that deploys in minutes and integrates directly into existing DJI Matrice 4 Series fleet operations. Its 108g build, comprehensive CZI Pilot software pipeline, and cloud synchronization capability make it a practical primary payload for fleet programs where speed of deployment and data completeness are both mission requirements. Dronefly supports enterprise operators in building DJI Matrice 4 Series payload programs around tools that solve real operational problems, and the CZI MF30-M4 is a strong fit for water resource, emergency management, and environmental monitoring fleets where aerial flow measurement capability directly affects program outcomes.
