Cone design for even more accurate date in especially high winds

Upgraded from the classic barrel shape design, the new Davis AeroCone Rain Collector solves the minor turbulence error when the wind hits the collector and then flows up and over causing the airflow to accelerate over the top. The new cone shape allows wind to flow around the cone, reducing turbulence and friction at the mouth of the collector.

Designed to meet the guidelines of the World Meteorological Organisation, this self-emptying tipping-bucket design is exceptionally accurate. Used to display daily and accumulated rainfall on our weather stations as well as rate of rainfall. The AeroCone comes with a flat mounting base that replaces the rain collector on your Vantage Pro2 sensor suite so it can be installed separately.

How it works
Rain enters the collector cone, passes through a debris-filtering screen and collects in one chamber of the tipping bucket. The bucket tips when it has collected an amount of water equal to the increment in which the collector measures (0.01" or 0.2 mm). As the bucket tips, it causes a switch closure and brings the second tipping bucket chamber into position. The rain water drains out through the screened drains in the base of the collector.

The collector is designed for years of accurate, trouble-free service. The shape is aerodynamically designed to minimise rainfall catch reduction caused by high winds. The body and base of the collector are constructed of tough, UV resistant plastic; the tipping bucket pivots on bearings that minimise friction and wear. Stainless steel adjustment screws under each chamber of the tipping bucket allow you to fine-tune the calibration of the Rain Collector.
