Q: In Symons rain gauge, the rim of the collector is set in a horizontal plane at a height of ________ above the ground level.
  • A. 20.5 cm
  • B. 12.7 cm
  • C. 30`.5 cm
  • D. 26.5 cm
Correct Answer: Option C - Symon's rain gauge is most common type of non-automatic rain-gauge, and is used by metrological department of government of India. • A rain gauge is an instrument used to measure the precipitation in a area. • A diameter of 12.7 cm is the collecting area on a non-recording rain gauge typically. • The circular collector's rim must be positioned at a height at approximately 30.5cm above the ground level on a honzontal plane • The measuring jar has a 0.1 mm accuracy range. • In order to determine the depth of the water, rainfall is measured in mm or cm.
