The greater the period of pressure variation in well air is, the greater is the response amplitude of well water level, while the smaller is the phaselag of the response.
井口空气压力变化的周期越大,则井水位的响应幅度越大,而响应的位相滞后越小。

The thermal sensor had a large lagphase, so the data got by the sensor of digital mass flow controller should be compensated in advance.
