2, the measurement of level of ground water：
The side of cup, electrical contact suspended type water gauge or float-type underground level gauge is surveyed in general subsurface water measurement using level of ground water
Formula.But there are the defects of the following aspects：（1）Due to judging that surveying the cup contact water surface will produce error, while the length of lining rope
There is also error, water level observation will not be very accurate.（2）Electrical contact suspended type water gauge is referred to by water level plummet, measurement ruler, the contact water surface
Show device（Sound equipment, light, pointer）, the instruments composition such as measurement ruler folding and unfolding dish, this kind of apparatus structure is more complex, and movable member is more, can
Poor by property, level measuring error is also larger.（3）Float-type underground level gauge generally can be in the well logging Guan Zhonggong of 10cm bores
Make, some can be mounted in work in the well of 5cm bores, water level wheel, float, counterweight diameter all very littles, small float incudes water level
The sensitivity of variation is poor, while underground water buried depth is larger, and suspension cable is long, also influences water level induction sensitivity.
