Davis AeroCone® Rain Collector w/Flat Base

The Davis AeroCone® Rain Collector with Flat Base (Model 6464) is a precision meteorological instrument designed to deliver accurate rainfall measurements in challenging wind conditions. Unlike conventional rain gauges that suffer from wind-induced measurement errors, the AeroCone's aerodynamic cone design streamlines airflow around the collection opening, significantly reducing flow distortions and horizontal wind velocity interference that typically causes under-reporting in exposed monitoring stations.

The engineering advantage lies in both external and internal geometry. The contoured aerodynamic profile minimizes turbulence around the funnel entrance, while the equalized internal pathway ensures consistent sample collection regardless of approach wind direction. This dual-feature design is particularly critical in coastal, mountainous, or open-field applications where wind speeds exceed calm conditions. The flat base provides stable, level mounting on standard rain gauge bases and installations, and the compact 9 x 8 x 11-inch dimensions make it compatible with existing Davis weather station setups and third-party data logging systems.

This rain collector serves meteorologists, hydrologists, agricultural operations, environmental monitoring networks, and research institutions that require reliable precipitation data for climate analysis, flood modeling, irrigation management, and watershed assessment. Facilities relying on legacy manual rain gauges or non-aerodynamic collectors will see measurable improvement in data quality, especially during high-wind events. The Davis AeroCone rain collector is a field-proven upgrade for anyone whose monitoring accuracy depends on unbiased rainfall capture in variable atmospheric conditions.
