PURPOSE:To measure the instantaneous amount of rainfall and snowfall and the amount of rainfall and snowfall in a set period by reserving rain and snow which are collected in a water receiver in a metering container capable of discharging, and measuring and converting the weight into the amount of rainfall and snowfall. CONSTITUTION:The metering container 3 is arranged under the center opening 2a of the funnel type water receiver 2 in an external housing 1 and fitted pivotally onto a support crossarm 4, and turnover measures 3a and 3b are formed in reverse triangular shapes by using wall bodies 3c and 3d to constitute the container; and the measures 3a and 3b are supported pivotally in an eccentric state on the intersection of the wall bodies 3c and 3d as an axial point 8. Then, the turnover angle of the container 3 is controlled by stoppers 4a and 4b and discharging funnels 6a and 6b are provided at both sides under the external housing 1 and the lead wire 7a of a strain gauge 5 fitted to the crossarm 4 is linked with a control part. Further, the amount of rainfall is calculated from weight variation in the container 3 which is measured by the gauge 5 in each measurement period of 10sec or 10min and stored, and the one-hour or one- rainfall amount of rain is calculated and stored, and displayed optionally. |
