Developed by CZI for emergency hydrological monitoring and routine water conservancy surveys, it integrates a 24GHz velocity radar and an 80GHz ranging radar into a single 108g payload that mounts directly to the Matrice 4 via PSDK.\u003c\/p\u003e\n\u003cp\u003eA single operator can complete installation and deployment in under two minutes, making it a practical tool for flood response teams that need actionable flow data quickly and without complex ground-based equipment.\u003c\/p\u003e\n\u003cp\u003eThe 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, operating at a recommended measurement height 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, enabling the system to compute reference water levels in real time.\u003c\/p\u003e\n\u003cp\u003eAll data displays live on the remote controller through DJI Pilot, while the full feature set — including automated flight missions, river cross-section flow calculation, data export, and cloud synchronization — is available through CZI Pilot software running on the drone controller.\u003c\/p\u003e\n\u003ch3\u003eCZI MF30-M4 Core Features and Advantages\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e24GHz velocity radar: measures surface flow from 0.1 to 20 m\/s with ±0.01 m\/s accuracy.\u003c\/li\u003e\n\u003cli\u003e80GHz ranging radar: water surface distance measurement from 0.18 to 30m at ±2mm accuracy.\u003c\/li\u003e\n\u003cli\u003eLightweight design: 108g payload mounts to DJI Matrice 4 via PSDK for fast field deployment.\u003c\/li\u003e\n\u003cli\u003eTwo-minute setup: single operator can install and deploy the payload in under two minutes.\u003c\/li\u003e\n\u003cli\u003eCZI Pilot software: complete flow monitoring from measurement to calculation and data export.\u003c\/li\u003e\n\u003cli\u003eAutomated flight missions: route-based automatic flight records all measurement point data.\u003c\/li\u003e\n\u003cli\u003eReference water level: supports Pearl River, Wusong, and other benchmark calculation systems.\u003c\/li\u003e\n\u003cli\u003eFlow calculation: Area-Velocity, International, and Liwen methods supported for cross-section flow.\u003c\/li\u003e\n\u003cli\u003eCloud synchronization: flow data syncs to cloud platform for visualization and data management.\u003c\/li\u003e\n\u003cli\u003eIP55 rated: sealed against dust and water jets for field deployment in light to moderate rain.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv style=\"position: relative; width: 100%; padding-bottom: 56.25%; text-align: center;\"\u003e\u003ciframe style=\"position: absolute; top: 0; left: 50%; transform: translateX(-50%); width: 100%; height: 100%;\" title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/SXSWUMYqEIc?si=EM-gXdPpZxvf8rtE\"\u003e\u003c\/iframe\u003e\u003c\/div\u003e\n\u003ch3\u003eApplications and Use Cases\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFlood 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.\u003c\/li\u003e\n\u003cli\u003eRoutine hydrological surveys: import river cross-section data and conduct scheduled surface velocity measurements at fixed monitoring points to support ongoing water resource management and reporting.\u003c\/li\u003e\n\u003cli\u003eRiver 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.\u003c\/li\u003e\n\u003cli\u003eWater 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.\u003c\/li\u003e\n\u003cli\u003eDisaster reconnaissance: deploy rapidly over inaccessible or hazardous waterways during disaster events to collect flow and water level data that ground teams cannot safely reach.\u003c\/li\u003e\n\u003cli\u003eDam and reservoir management: conduct scheduled flow measurements upstream and downstream of dams and reservoirs to support discharge management, spillway operations, and safety monitoring.\u003c\/li\u003e\n\u003cli\u003eIrrigation and agriculture water management: measure flow rates in irrigation channels and agricultural water supply systems to support water allocation decisions and efficiency monitoring.\u003c\/li\u003e\n\u003cli\u003eEnvironmental monitoring: collect surface velocity and water level data in rivers and wetlands for ecological research, habitat assessment, and environmental compliance reporting.\u003c\/li\u003e\n\u003cli\u003eUrban stormwater management: measure flow velocity in urban drainage channels and stormwater systems during and after heavy rain events to support drainage capacity analysis and flood risk assessment.\u003c\/li\u003e\n\u003cli\u003eBridge and infrastructure inspection support: measure flow conditions near bridge piers, culverts, and hydraulic structures to assess scour risk and support infrastructure safety evaluations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe CZI MF30-M4 exists for water resource professionals who need fast, reliable surface flow data from a drone without the logistical burden of traditional ground-based measurement equipment.
