The RainVUE™️20 is ideal for many hydrological or meteorological applications such as weather stations and flood warning systems. The RainVUE™️20 is an SDI-12 tipping bucket rain gauge in the RainVUE family of products. Advanced algorithms and digital processing within the sensor compensate for errors caused by high-intensity rain and provide accurate precipitation and intensity measurements. Constructed of an aerodynamic powder-coated aluminum funnel, the RainVUE™️20 is robust and minimizes the amount of liquid precipitation that is lost due to the effects of wind. This rain gauge offers the user flexibility with the option to select from a series of set cable lengths or a user-defined cable length.
