Can the vision-fusion radar level meter keep measuring reliably through typhoons and heavy monsoon rain?

The worst failure mode for flood-monitoring hardware is going dark exactly when data matters most — and typhoon downpours are precisely that moment. Reliability of the vision-fusion radar level meter in extreme weather comes down to several design traits:

  • Limited rain attenuation: 76-81 GHz mmWave does attenuate more in heavy rain than lower-frequency radar, but level measurement distances are meters to tens of meters, and the SNR headroom from the 4 GHz bandwidth fully absorbs storm attenuation — field tests show the echo stays locked on the water surface through intense rainfall;
  • Wind chop and debris: typhoon conditions churn the surface with floating leaves and trash. FMCW multi-frame averaging suppresses random fluctuations, and clutter echoes are separated from the true water-surface return by signal strength and Doppler signature. If a reading still looks suspect, the 5-megapixel camera captures the scene on demand so dispatchers judge data credibility while looking at a photo — something pure-radar devices cannot offer;
  • Equipment survival: full IP68 construction tolerates short-term submersion; 9-28 VDC wide-range input with solar plus a 96 AH battery keeps the site running when grid power fails in the disaster, and the low-power design (2+ years endurance) leaves ample margin for consecutive overcast days;
  • Telemetry resilience: cellular towers can be damaged during typhoons — EC32-based sites run 4G as the primary link, EC60 adds NB-IoT, and dual-carrier SIM setups fail over automatically when one network goes down.

Deployment advice for flood season: recheck zero-point calibration and SPD status windows beforehand, set two alarm tiers (warning level and guaranteed level), temporarily raise camera snapshot frequency (for example hourly) during the season, and afterwards replay the full level-plus-image chronology for post-event review and insurance evidence.
