HY FFZ-03自动水面蒸发站比测分析研究

Comparative Measurement and Analysis of HY•FFZ-03 Automatic Water Surface Evaporation Station

摘要:

HY FFZ-03 水面蒸发站是一种新型的数字式全自动水面蒸发器,仪器采用主动定量汲水方案及高精度、 低迟滞、抗干扰能力强的磁致伸缩液位传感器进行蒸发桶内水位观测,采用暴雨期间蒸发量处理算法,克服了暴雨期间蒸发数据误差偏大的问题。文章对山东省南村水文站 HY·FFZ-03 全自动数字水面蒸发站进行了连续2年的逐日比测,结果显示,蒸发站系统运行稳定,精度满足水文测站蒸发观测要求。

Abstract:

The HY FFZ-03 water surface evaporation station is a new type of digital automatic instrument of water surface evaporator. It adopts an active quantitative water drawing scheme and a high-precision, low-hysteresis, and strong anti-interference magnetostrictive liquid level sensor to observe the water level in the evaporation bucket. It also uses an evaporation processing algorithm during heavy rains to overcome the problem of large errors in evaporation data during heavy rain periods. This paper conducts a two-year consecutive daily comparative measurement on the HY FFZ-03 fully automatic digital water surface evaporation station at Nancun Hydrological Station in Shandong Province. The results show that the evaporation station system operates stably, and its accuracy meets the requirements evaporation observation at hydrological stations.
