摘　　要：小沙湾水厂是黄河地表水给水工程的重要组成部分,是准能集团的重要水源地,而精准的水位数据对泵站取水工作有较大的影响。以浮子式水位计示值为参照,设计了投入式水位计示值的对比试验,对影响传感器精度的主要因素之一温度进行了研究,总结了温度与示值误差之间的关系。结果发现,在10~18℃时,水温对传感器精度影响很小;在18~25℃时,水温越高传感器精度越低;在26~30℃时,传感器精度随温度升高而升高。Xiaoshawan water plant is an important part of surface water supply project of the Yellow River,and also an inportant water sources of Zhunneng Group.The accurate data of water level has a great impact on the water intake work of pump station.Taking the float level meter as a reference,a comparative test of submersible water level meter was designed in this paper.Temperature,one the main factors affecting the precision of the sensor,was studied,and the relationship between temperature and indication error was summarized.The results showed that the influence of water temperature on the accuracy of the sensor was small at 10~18°C,and the accuracy of sensor accuracy decreased with the increase of water temperature at 18~25°C,while increased at 26~30°C.
