目前英额巴扎水文站观测水位主要应用HW-1000C非接触超声波水位计及人工观测水位两种方法,将两种方法比测得到的数据通过对其时间的分析、不同水位级水位的分析及波浪大小不同情况下的分析,可以得出其时间误差、中低水、中水、高水的系统误差、综合不确定度均符合《水位观测标准》GBJ138-90的相关规定,从而确定HW-1000C无线远传型非接触超声波水位计可以正常使用。
At present, there are two methods for the observation of the water level at the Yingbo Bazha Hydrological Station: the HW-1000C non-contact ultrasonic water level meter and the artificial observation water level. The data measured by the two methods are compared by analyzing the time, analyzing the water level at different water levels The analysis of the different wave size, we can draw the time error, the system error of low water, medium water and high water, the comprehensive uncertainty are in line with the relevant provisions of “water level observation standards” GBJ138-90 to determine the HW- 1000C wireless remote non-contact ultrasonic water level gauge can be used normally.
