Mottech Rain Bucket Sensor
Overview
Mottech Rain Bucket Sensor is a hydrology, meteorological instrument used to measure
the nature of rainfall, and it converts the precipitation into a pulse signal output.
Designed with insect-proof nets, free blocking nozzle and built-in leveler. The model can be used in meteorology, hydrology, agriculture, forestry, field monitoring stations and other industries.Combined with rainfall recorder can be used to measure measure precipitation, precipitation intensity and precipitation time. Mottech Rain Bucket Sensor can be connected directly to any controller in Mottech’s system via digital input.

Working Process
Rainfall is captured in the 200mm diameter 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 center and has a preset calibration to tip for 0.2 mm of 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.
