摘要
文章首先简要介绍雨量传感器现场校准方法和实验室检定方法及相关标准装置。然后,选取不同口径的雨量传感器通过实验室标准装置模拟现场校准与实验室检定进行对比实验。表明在雨量传感器现场校准工作中,选用的降水量标准值同实验室检定选用的降水量标准值不能统一,造成在相同环境条件下,两种方法检测同一台雨量传感器的检测误差不同,可能影响雨量传感器计量结果的准确性。最后,提出几点建议,为以后自动气象站雨量现场校准方法的修改及标准器的选择提供技术参考。
This paper first briefly introduces the field calibration methods,laboratory verification methods and relevant standard devices of rainfall sensors.Then,the rainfall sensors of different calibers have selected to compare the field calibration with the laboratory verification by means of laboratory standard devices.It shows that,in the field calibration work of rainfall sensors,the standard value of precipitation selected for rainfall sensors cannot be consistent with the standard value of precipitation selected by the laboratory verification.Under the same environmental conditions,the accuracy of the measurement results of the rainfall sensor may be affected by the difference between the two methods.Finally,some suggestions are put forward to provide technical references for the modification of the field calibration methods and the selection of standard instrument.
