5. Operation Operation of the gauge Rainfall is measured by the well-proven tipping bucket method. Precipitation is collected by the funnel and flows through a plastic gauze filter, trapping and removing any leaves, dirt, etc. Figure 4. Water then drips from the nozzle into one of the two halves of the tipping bucket. Figure 4 - Filter and filter cap (left) / Nozzle delivering water into tipping bucket (right) The internal tipping bucket assembly rotates around precision rolling pivot bearings. -
