Claims

[Scope of utility model registration request]

A water storage chamber is provided inside the transparent upper body with an on-off valve at the top, a flow rate adjustment valve is installed on one side of the water storage chamber, and a connecting part is attached, and the lower end of the pipe connected to the bottom of the water storage chamber has an opening on the bottom surface. A first fluid sensing sensor having an upper fixed point and a second fluid sensing sensor having a lower fixed point are attached to the upper and lower parts of the pipe, and a base having a drain port on one side is connected. a recess and an opening of the lower body to which a sampling cylinder is attached that accommodates a soil sample therein and a mesh plate is attached to each of the upper and lower surfaces, a support table on which a base is placed, and a holding plate inserted through the pipe; This variable water permeability tester is constructed by connecting the two parts with a threaded rod and tightening them with a wing nut, connecting the connecting part to an automatic pressure regulator with a hose, and connecting upper and lower fluid detection sensors and a variable water level counter unit.
