260-6464 and 260-6466 AeroCone Rain Collectors
The AeroCone Rain Collector reduces wind-induced errors by providing a more aerodynamic path around the collector. The design improves rain data accuracy in high wind situations where the horizontal wind velocity can cause under-reporting.
The AeroCone Rain Collector is designed to meet the guidelines of the World Meteorological Organization. Rain enters the collector cone, passes through a debris-filtering screen, and collects in one chamber of the tipping spoon. The spoon tips when it has collected an amount of water equal to the increment in which the collector measures (0.01 inch or 0.2 mm). As the spoon tips, it causes a switch closure. The rain water drains out through the screened drain in the base of the collector.
The collector is designed for years of accurate, trouble-free service. The shape is aerodynamically designed to minimize rainfall catch reduction caused by high winds. The body and base of the collector are constructed of tough, UV resistant plastic.
