The simple probe exposed type electric measuring water level gauge can be manufactured by self on general projects, and the principle is as follows: the lower ends of the double-wire electric wires are tied on two sides of the slender insulator, the conductors at the lower ends are exposed, the double-wire electric wires can be communicated through a water body after entering water, the upper ends of the double-wire electric wires are connected through a universal meter on the earth surface, whether the water level meter enters water or not is determined by testing resistance change, and the water level can be measured by lifting rope scales from the water level meter. However, when large-flow water pumping, large water level lowering or large-flow water injection test is performed in hydrogeology, a continuous water film is easily formed on the surface of the water level gauge due to the existence of the water leaching water, so that the water level gauge cannot find the water level at all, or a gas-liquid mixture with a certain thickness is formed between the water body and the air due to the fact that the water body carries a large amount of air into a well, and a continuous and stable water level cannot be formed. Under the condition, a liquid level pipe is generally put into a well in engineering, and then an electric measuring type water level meter is put into the liquid level pipe, but the liquid level pipe is small in pipe diameter, so that the operation is difficult, time and labor are wasted, and the liquid level pipe is easy to break, thereby bringing about very serious potential safety hazards.

(3) After about half an hour of water injection, the water level meter in the prior art is put into a well to measure the water level burial depth, but the water level alarms at different depths are in an intermittent working state, and the water level surface cannot be found successfully. The analysis is caused by the fact that the gas-liquid mixture formed in the well is too thick due to the fact that the water quantity is large.
(4) Will utilize the utility model discloses the fluviograph (from taking the liquid level pipe, the length to 100cm of liquid level pipe is connected with the fluviograph through the screw thread), put into the well, quick, successfully made the alignment water level. The surface burial depth of the obtained stable water liquid is 130.12 m.
(5) And calculating by using the water level rise value, the water injection quantity and the pore diameter to obtain the permeability coefficient.
And (4) conclusion: in the water pumping test and the water injection test for obtaining the hydrogeological parameters of the stratum, when the water surface is stable and the water pumping amount or the water injection amount is small, the simple probe-exposed electric measuring type water level meter can meet the requirement. And the utility model provides a from water level gauge of taking liquid level pipe when the water pumping volume or water injection volume are great, the water injection when leaching that can avoid aquifer water jump to produce and water injection test forms continuous water film on the water level gauge surface, and leads to the phenomenon that the water level gauge is forced to communicate above the surface of water, and the water level measurement is accurate rapidly.
