Technical Description

The RainVue 20 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. It tips when the first bucket fillsto a fixed calibrated level, and then the balance arm moves the second bucket undthee furnne l. A magnet attached to the balance arm actuates a reed switch as the bucket tips.

The aerodynamic design of the RainVue 20 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 RainVue 20 also includes a microprocesstohrat corrects for rainfall intensity and outputs an SDI-12 signal.
