Document Type and Number:
WIPO Patent Application WO/2021/029481
Kind Code:
A1
Abstract:
The present invention relates to a hybrid precipitation meter capable of adjusting the amount of water collection. The technical problem to be solved is to reduce measurement errors occurring in a tipping cup due to local heavy rain or a rapid increase in the amount of rainwater to be measured by adjusting the amount of rainwater collected in the tipping cup when the amount of rainwater collected in the tipping cup reaches a certain capacity. Disclosed is a hybrid precipitation meter capable of adjusting the amount of water collection, comprising: for example, a water-collecting cup which collects rainwater and discharges same downward through a discharge path; a tipping bucket which collects the rainwater discharged from the water-collecting cup and performs a seesaw motion according to the weight of the collected rainwater; a first load cell which measures the weight of the rainwater collected in the tipping bucket; a sensor which detects a left and right rotation according to the seesaw motion of the tipping bucket; a control part which measures the amount of precipitation by counting the rotations of the tipping bucket through the sensor, outputs a first control signal when the rotations of the tipping bucket is detected through the sensor, and outputs a second control signal when a second weight is measured, the second weight being less than a first weight measured through the first load cell when the tipping bucket is rotated; and an automatic valve which operates to reduce the opening rate of the discharge path by a certain value when the second control signal is output and to increase the opening rate of the discharge path to the maximum when the first control signal is output.
