数字化水位观测仪零漂分析

摘要

digital water level LN-3 type observation instrument exist certain zero drift problem.The results of experiment at Ningde 1 well show that instrument room temperature,air temperature,well water temperature,probe buried deep change are the important reasons of zero drift of digital water level instrument,and humidity and public data acquisition are no affect on the zero drift.Hereby,some solutions and suggestions are put forward for improving the reliability and continuity of the water level observation data.%数字化水位LN-3型观测仪器存在一定的零漂问题,并通过宁德1号井实验结果表明,仪器室温度、气温、井水温、传感器埋深变化是数字化水位仪器零漂的重要原因,而水位仪器的零漂与湿度、公共数采无关,据此提出解决方案和建议,以提高水位观测资料的可靠性和连续性.
