The aim of this study is to investigate the main purpose for the utilization of double layer tipping bucket sensors, such as installed in Tegal Climatological Station (TCS), Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG). Hydraulic to electric analogy and rainfall interception models from Calder, Rutter, and Gash are used as the investigation method. The result shows that double layer tipping bucket sensors are dedicated to measure high intensity rainfalls.
