Flowed into water supply bottle in varying head pipe, flow velocity is difficult to control to, careless slightly flowing water exceedes scale and even spilt from the glass mouth of pipe, needs
Unnecessary head is suctioned out from top, complex operation wastes time and energy；
3. reading head data by varying head pipe, due to the limitation of operating personnel's height of sighting line, reading is easily produced and regarded
Difference；
When reading head, it is desirable to which sight is parallel with concave meniscus lower edge in varying head pipe, and normal person need to could reach by stool
To 1.9m realization height, while with the progress of infiltration, height of sighting line is adjusted therewith, it is high that reading personnel need to adjust sight therewith
There is possibility greatly in degree, parallax, and systematic error is larger.
4. stopwatch need to be configured in addition, instrument overall function is poor.
Experiment need to test the change of head in predetermined time interval by timer, and stopwatch, laboratory apparatus need to be configured in addition
Function lacks globality.
