Research on the Calibration Method of SWY-II Water Level Sensor

In this paper,a laboratory calibration method is proposed for water level sensor accuracy calibration and improved according to the situation of seismic station,on this basis,a water level sensor calibration method is provided for onsite calibration at seismic station.The new water level sensor calibration method can solved the systemic error caused by the environmental factors and the components of pressure sensitive nonlinear factors.
