Application of Digital Float Water Level Gauge in Hydrology Station of Chanzhi Reservoir
Water level observation is one of the important work of hydrology,so the selection and application of water level gauge is vital.This paper introduces the structure and working principle of WFX-40 digital float water level meter.In order to verify the accuracy and reliability of observation data,227 sets of manual and automatic observation water level data from June to October 2022 are collected and sorted out for comparison and error analysis.The results show that the automatic observation of water level data meets the comprehensive uncertainty and systematic error specification requirements of 95％confidence level,which proves that the accuracy and precision of WFX-40 can meet the requirements of water level observation specification.The collected data is accurate and reliable which can be used in data compilation.The automatic monitoring can replace the traditional manual observation,which can greatly reduce the workload of manual observation of water level,realize the automatic hydrological measurement and report,and provide technical support for the popularization of the same type of self-measuring water level meter.
