Kipp & Zonen introduces the CVF4, a new ventilation unit for its pyranometer and pyrgeometer range. Ventilation of radiometers improves the reliability and accuracy of the measurement by reducing dust on the dome, removing dew and rain droplets, and melting frost and snow, which would otherwise affect the measurement. The latest flow simulation software, microflow, and temperature measurement devices were used in the development process of the CVF4 to maximize its performance. At the top of the pyranometer dome, the flow is very high and it swirls to improve the air distribution over the dome. The position of the heaters and the new cover material ensures only half the heating power is needed to melt frost and snow compared to older ventilation units. CVF4 is easy to use, operates in all weather conditions, and significantly improves the availability of high-quality measurement data from pyranometers and pyrgeometers.
