80GHz Visual Fusion Radar Flow Meter: See What You Measure in Urban Drainage
The 80GHz visual fusion radar flow meter from Ecolor Technology — the SITUMAN series — redefines urban drainage monitoring by merging millimeter-wave precision with real-time visual intelligence. At just ¥4,500 per node, it delivers non-contact, self-diagnosing, time-synchronized level, velocity, and HD video data — ending decades of blind measurement in underground water infrastructure.
Designed for hostile environments — high humidity, H₂S corrosion, floating debris, sediment, and total darkness — this 80GHz radar flow sensor with integrated camera enables engineers to instantly verify whether an alarm reflects true overflow, sensor fogging, or surface obstruction.
Beyond Blind Sensors: The Visual Sensing Revolution
For decades, urban drainage relied on ultrasonic or pressure-based level sensors — vulnerable to fouling, drift, and zero visibility during maintenance. Over 68% of municipal sewer monitoring nodes in China’s Tier-2 cities require ≥3 unscheduled service visits annually due to sensor failure (China Water Association, 2024).
The SITUMAN 80GHz visual fusion radar flow meter ends that era. By fusing FMCW Doppler sensing with synchronized 2MP HD video, it transforms each installation into an autonomous diagnostic station — validating its own readings in real time and eliminating guesswork in incident response.
Why “See What You Measure” Is Operational Necessity
Urban sewers are among the most challenging environments for instrumentation. Traditional radar sensors — even 26GHz or 60GHz models — suffer from multipath interference off irregular well walls and signal attenuation from surface scum.
A 2023 field study across 142 manholes in Hangzhou and Chengdu found non-contact radar units *without* visual verification triggered 22% more false alarms for overflow events. Worse, 41% of maintenance delays were attributed to inability to visually confirm sensor readings — a critical bottleneck in emergency response.
Precision Engineered for the Underground Battlefield
At its core lies an industrial-grade 80GHz FMCW radar module, operating in the world’s least congested mmWave band. It delivers ±1mm level accuracy and ±2% velocity accuracy up to 30 meters — far surpassing legacy single-point Doppler sensors.
SITUMAN applies adaptive beamforming for cross-sectional velocity profiling — essential for irregular pipe geometries. Its integrated stepper motor enables remote angle adjustment (±15° vertical / ±30° horizontal), letting operators reposition the radar beam away from ladders or sludge — without entering confined spaces.

From Data Silos to Unified Intelligence: The SITUMAN-COSP Framework
Ecolor’s proprietary SITUMAN水利COSP model (Control-Observation-Sensing-Prediction) unifies level, flow, and video into a single time-synchronized data object — where every flow reading carries embedded visual context, GPS metadata, and AI-generated confidence scoring.
In pilot deployments across 37 wastewater pumping stations in Guangdong Province, average incident resolution time dropped from 112 minutes to 27 minutes — a 76% reduction — because engineers received not just an alert, but a verified video clip showing root cause: genuine overflow, misaligned sensor, or floating debris.
Beyond Drainage: Three High-Impact Use Cases
Eco-Flow Compliance Monitoring
At hydropower tailraces, regulators demand tamper-proof, human-verifiable records of minimum downstream releases. SITUMAN’s non-contact design prevents vandalism and biofouling — while its HD video satisfies audit requirements for ‘visual evidence of flow’.
Smart Irrigation Districts
In Zhejiang’s high-standard farmland projects, SITUMAN monitors canal cross-sections with sub-centimeter level stability — eliminating costly stilling wells and enabling dynamic gate control via HERO V9’s Modbus TCP output.
Integrated Water-Quality Nodes
With optional RS485 ports, SITUMAN accepts inputs from multi-parameter probes (pH, turbidity, NH₃-N), creating true ‘flow + quality’ stations. A Jiangsu Yangtze tributary pilot reduced compliance reporting labor by 63% by auto-correlating turbidity spikes with flow anomalies.
The Economics of Certainty: Why ¥4,500 Is a Strategic Investment
While standalone ultrasonic sensors cost ¥800–¥1,200, lifecycle analysis tells a different story. A 2024 Tsinghua University study tracked 216 nodes over 36 months: traditional units incurred ¥2,140/year in labor, vehicle dispatch, and downtime. SITUMAN sites averaged just ¥380/year — thanks to zero confined-space entries, 5-year calibration-free operation, and predictive alerts (e.g., “lens soiling detected — clean recommended in 14 days”).
When factoring in avoided penalties — up to ¥50,000 per overflow violation under China’s 2023 Ecological Damage Compensation Regulations — ROI is achieved in **under 11 months**. This isn’t just hardware — it’s operational certainty, priced.
