Research for Automatic forecasting system of weighting rainfall recorder

In order to solve the problem of siphon rainfall recorder's hard to control automaticly and the measurement error when siphoning, we research the Automatic forecasting system based on double barrel double siphon rainfall recorder and ARM processing terminal. By using double barrel double siphon structure and weighing cell, we eliminate the rainfall error caused by siphon loss, and achieve the automatic collection of rainfall data.
