What this product is

Precise measurement of liquid precipitation

The tipping-bucket rain gauge collects precipitation through a 200 mm diameter funnel and directs it to a calibrated double bucket. Each tip corresponds to 0.2 mm of precipitation, and the built-in mechanism makes it possible to track the amount, intensity and duration of rainfall.

The technical values apply to the selected RS485 version for integration with the AGRO VEDA station.

Installation

Operating principle and mounting

  • Precipitation from the funnel is directed into the divided tipping bucket, calibrated to 0.2 mm per tip.
  • When one side fills, the bucket tips and empties, and the other side takes over the inflow.
  • During installation, level the device with the foot screws and fix it to a stable platform with three screws.
  • The mesh in the funnel and the drain guard reduce the entry of leaves, insects and other debris.
