Tipping bucket rain-gauge

The 'smart' digital tipping bucket rain gauge by ICT International provides reliable measurement of rainfall and intensity. The design includes several features to maintain accuracy of measurement, including a siphoning device which 'smooths' the flow of water through the system, minimising errors associated with varying intensity of rainfall.

Rainfall is captured in the 203 mm diameter collector funnel and is directed through a delivery pipe to fill a divided tipping bucket device. The bucket is pivoted through its centre and has a preset calibration to tip for 0.2, or 0.5 or 1.0mm of rainfall. When full, the bucket pivots and empties. This action magnetically closes and opens a reed switch, sending a pulse signal to the data logger or electronic counter. Through this tipping 'seesaw' action, the other side of the bucket is aligned to receive the flow from the delivery pipe.

The recording and tipping cycle continues with rainfall while fine stainless-steel mesh prevents debris such as dirt and insects from entering the workings of the rain gauge.

Multi-use flexibility

ICT's 'smart' tipping bucket rain gauge can be used as an integral component of the EnviroStationTM weather station; a stand-alone 'plug and play' rain gauge used with an ICT Smart Logger; a standard tipping bucket rain gauge for integration with an existing weather station or data logger.

The smart rain gauge can calculate maximum rain rate, daily total from 9am to 9am as well as the 24-hour total. When connected to a Smart Logger the rain gauge can be used to calculate total rainfall in any logging period that is set in the logger.
