Tipping Bucket Raingauge TB3 100-06 Issue 12: 29/7/2014
i. Site Selection
Rainfall measurements are intended to be representative of the actual rain falling on a given
area. Some of the more important factors which influence the representativeness of a gauge
are as follows:
 Site the gauge on level ground where possible. Avoid sloping sites.
 Site should have adequate protection from strong winds.
 Site should be free of large obstructions such as buildings and trees.
 Provide suitable ground surface to avoid splashing into the gauge.
ii. Setting up
 Install the gauge on the foundation. A suggested foundation is detailed
in Diagram 1.
 Loosen the three enclosure securing screws and the enclosure.
 The gauge is provided with a level. Proceed to level by adjusting the
hold down anchors as required.
 Connect lead to the raingauge terminals, in accordance with Diagram
3, and to the recording device, in accordance with manufacturer’s
instruction manual.

V. TEST OPERATION
 Manually tip the bucket a number of times, ensuring that each tip is
being recorded and that the tilting mechanism is operating freely.
 Replace and secure the enclosure.
