The capacity of individual compartment of tipping bucket type rain gauge is?

  • A.0.50 mm
  • B.0.25 mm
  • C.1.00 mm
  • D.0.15 mm

Answer: B

Each compartment of a tipping bucket gauge holds 0.25 mm of rainfall.

In the tipping bucket gauge, rain from the funnel fills one of two small buckets mounted on a pivot. When the bucket has collected the equivalent of 0.25 mm of rain, it tips, empties, and brings the other bucket under the funnel. Each tip is recorded electrically, so the number of tips gives the rainfall depth and their timing gives the intensity.

Larger capacities such as 0.50 or 1.00 mm would make the record too coarse, and 0.15 mm is not the standard figure.
