摘　　要：超声式雨量计采用水介超声式换能器测量液位变化测得雨量,由进水区、缓存区、测量区、排水区组成,实现自动测量、输出雨量数据,可解决传统雨量计大雨强下计量误差较大的问题,雨量分辨力为0.1 mm。实验表明:在1.0~8.0 mm/min雨强下的准确度误差≤1%,达到Ⅰ精度标准,误差重复率≤1%,仪器性能稳定。超声式雨量计性价比相对较高,后期完成野外实验,可广泛推广应用。The ultrasonic rain gauge measures the change in liquid level through a water-based ultrasonic transducer to measure rainfall.The rain gauge is composed of an inlet area,a buffer area,a measurement area,and a drainage area,achieving automatic measurement and outputting rainfall data.This rain gauge can solve the problem of large measurement errors in traditional rain gauges under heavy rain,with a rainfall resolution of 0.1 mm.The experiment shows that the accuracy error under rain intensity of 1 to 8 mm/min is≤1%,meeting the accuracy standard of I;the error repetition rate is≤1%,and the instrument performance is stable.Due to its relatively high cost-effectiveness,it can be widely promoted and applied after completing field experiments in the later stage.
