Innovative Dual-Bucket Design Integrated with IoT Technology Solves Traditional Rainfall Monitoring Challenges
I. Industry Pain Points: Limitations of Traditional Rainfall Monitoring
In the field of meteorological and hydrological monitoring, the accuracy of rainfall data directly affects important decisions such as flood warning and water resource management:
- Insufficient accuracy: Errors in traditional rain gauges increase significantly during heavy rainfall
- Susceptible to interference: Debris like leaves and sediment easily causes funnel clogging
- Data lag: Manual data collection is inefficient with poor real-time performance
- Poor environmental adaptability: Measurement stability insufficient under extreme temperature conditions
During the 2023 flood season, a provincial meteorological bureau experienced delayed flood warnings due to data deviations from traditional rainfall monitoring equipment, highlighting the urgency of equipment upgrades.
II. Technological Innovation: Breakthroughs of New Generation Tipping Bucket Rain Gauge
1. Precision Measurement Structure

2. Intelligent Anti-Clogging System
- Double-layer filtration device
- Upper coarse filter intercepts large particles like leaves
- Lower fine filter prevents small sediment particles from entering
- Self-cleaning inclined surface design utilizes rainwater flow for cleaning
3. Enhanced Environmental Adaptation
- Wide temperature range operation capability
- Operating temperature: -30℃ to 70℃
- Stainless steel bearings, corrosion and wear resistant
