Research-Grade Pluviometer PLV-2

ICT International’s PLV2 Pluviometer consists of a tipping bucket rain gauge with 0.2mm tip and Mini-Log Datalogger, offering a stand-alone measurement system suitable for any short or long term application.

Accurate Rainfall Measurement

The design of the pluviometer includes several features to maintain accuracy of measurement. This includes a syphoning device which “smooths” the flow of water through the system, which minimalises errors associated with varying intensity of rainfall. Rainfall is captured in the 200mm 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 0.2mm 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. Other features to ensure maintained accuracy include a level bubble adhered to the base.

Easy-To-Use Data Collection

The compact MiniLog Data Logger is suitable for any short or long term, remote data logging application. It features very low current consumption, requiring only one 3.6V Lithium battery for up to 10 years use. Rainfall events from the rain gauge are stored in memory, which can be downloaded to either a laptop or desktop computer using an RS-232 serial cable and Terminal program.
