摘要
河流水位测量是水利信息化工程中的重要环节。据调查,现用于河流的水位传感器大都存在受测量环境影响大、可靠性不强、不利于系统集成等缺陷。电极式水位传感器是一种应用于锅炉汽包水位检测的传感器,采用数字测量方式,具有不受环境参数影响、稳定可靠等优点。通过对其感应方式进行改进,采用交变窄脉冲驱动电极,克服了传感器电极电化腐蚀,使其适用于河流的水位测量。经长时间实地验证,模型正确可靠,具有实用价值。
Water level measurement of river is an important link According to the survey, available water level sensor which used of water conservancy for river are mostly information project. exist problems like impacted by environmental, small reliability and not suitable for system integration. Electrode type water level sensor is a sensor used in boiler drum water level detection which adopts digital measuring method, is not influenced by the environment parameter, works stable and reliable. Through improve the inductive approach, used in narrow pulse driving electrodes, overcome the sensor electrode electrochemical corrosion, and make it suitable for river water level measurement. Verified by field for a long time, the model is accurate and reliable, and has practical value.
