Visão Geral

The RainVue™️10 is ideal for many hydrological or meteorological applications such as weather stations and flood warning systems. The RainVue 10 is an SDI-12 tipping bucket rain gage 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 plastic funnel, the RainVue 10 is cost effective and minimizes the amount of liquid precipitation that is lost due to the effects of wind. This rain gage offers the user flexibility with the option to select from a series of set cable lengths or a user-defined cable length.

Descrição Técnica

The RainVue 10 funnels rainfall through a stainless-steel gauze filter that traps and removes debris. The rainfall flows through a nozzle into one of the two halves of the tipping bucket. The internal tipping bucket assembly rotates around precision rolling pivot bearings and tips when the first bucket fills to a fixed calibrated level. Then the balance arm moves the second bucket under the funnel. A magnet attached to the balance arm actuates a reed switch as the bucket tips.

The aerodynamic design of the RainVue 10 prevents wind from carrying the rainfall away from the collecting vessel. With traditional cylindrical rain gages, wind can reduce the rainfall catch by up to 20 percent. The deep funnel catch also minimizes splashing out and loss due to high winds and heavy rainfall. The RainVue 10 also includes a microprocessor that corrects for rainfall intensity and outputs an SDI-12 signal.
