The Tipping Bucket Rain Gauge measures precipitation. It consists of a collector, a triangular-shaped bucket, and an electric transmitter. The gauge catches precipitation in a collector, then funnels the water to the tipping bucket. Once a preset weight of rainfall has accumulated, the bucket tips like a seesaw, empties, and exposes the other side to the rain. It takes 0.1seconds for the bucket to tip. After each tip, the measured water is funneled out the bottom of the gauge. The bucket makes an electrical contact during the tip, so that each time it tips, an electronic signal that is recorded to a datalogger. The tipping bucket rain gage is good at measuring drizzle and very light rainfall . It is less precise in heavy rain when measurements may be missed during the time the buckets are moving into place.
