RK400-11 Rainfall Sensor

Description

Rainfall is captured in the collector funnel and is directed through a delivery pipe to fill a divided ABS injection molded tipping bucket device.The bucket is pivoted through its centerand has a preset calibration to tip for 0.2 or 0.3mmof rainfall. When the bucket is “full”, it 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. This recording and tipping cycle continues with rainfall.
