水位校测对提高流体观测网的运行质量与监测效能具有重要意义，是规范井水位观测技术的关键环节。基于电极法的水位校测装置广泛应用于地震流体观测台站，其校测精度受到装置本身、使用者熟练程度等因素影响。为提高水位校测装置的测量精度，设计一种地震流体井下水位校测装置，采用多电极探针的校测探头，并设计读数模块，将各电极接触水面的电信号通过无线模块传输，触发蜂鸣器报警和指示灯显示。该设计方案的可行性在实验中得到验证。
Water level calibration plays an important role in improving the operation quality and monitoring efficiency for the well water level observation network and is essential to standardize the well water level observation technology. The water level calibration device based on the electrode method is widely used in seismic monitoring stations of underground fluids; its calibration accuracy is affected by factors such as the device itself and the user's proficiency. In order to improve the measurement accuracy of the water level calibration device, a novel water level calibration device is proposed in the paper. In the structural design, a multi-electrode calibration probe is used, and a reading module is designed. In addition, a wireless module is also applied to transmit electrical signals and trigger the buzzer alarm and the indicator light once the electrodes contacting the water surface. The design method has been verified in experiments.
