Tipping Bucket Rain Gauge

A Tipping Bucket Rain Gauge (TBRG) consists of a collector shaped like a funnel, two ‘buckets’ (0.2mm, 0.25mm, 0.5mm or 1.0mm resolution) mounted on an axle, and an electronic reed switch. Intercepted rainfall and is funnelled into one of two small buckets, which when full, tips and causes a magnet to contact the electronic reed and generate a digital pulse which is recorded by a connected data logger or node.


The rainfall intensity of a tipping-bucket gauge is calculated based on the number of tips in a periodic sampling rate and averaged over a chosen time interval.
