No-moving-parts rain gauge and disdrometer providing rain intensity, accumulated precipitation, drop-size distribution and hail detection for professional meteorological, hydrological and infrastructure monitoring.
Typical Applications
- Meteorological observation networks

- Agriculture and vineyard monitoring
- Infrastructure and erosion monitoring
- Precipitation research and radar validation
The RainFlow RF4 Disdrometer combines a precision rain gauge, drop-size disdrometer and hail detection sensor in one rugged, no-moving-parts instrument for continuous precipitation monitoring. Using acoustic impact sensing and embedded signal processing, RF4 measures instantaneous and averaged rain intensity, cumulative rainfall, raindrop count and drop-size distribution, while identifying hail events and supporting very-low-power autonomous operation across meteorological, hydrological, transport and renewable-energy monitoring networks.
Key Features
- Combined rain gauge, disdrometer and basic hail detector
- Acoustic impact precipitation measurement
- No mechanical tipping bucket or moving sensing mechanism
- No optical measurement windows requiring routine cleaning
- Instantaneous and averaged rain intensity
- Cumulative rainfall measurement
- Individual raindrop counting
- Real-time drop-size distribution
- Hail occurrence and impact detection
- Internal data logging
- Very low power for solar/battery stations
- SDI-12 and serial ASCII communications
- Optional Modbus RTU RS-485 integration
- Optional 4–20 mA industrial output
- Rugged stainless-steel and aluminum construction
Because RF4 uses an acoustic metallic sensing head instead of a tipping mechanism or exposed optical path, it combines low maintenance with information a conventional rain gauge cannot provide—especially drop-size distribution and hail-event detection.
