In the present invention, there is disclosed a permeameter with a proportioning pump, intended for testing hydro-physical properties of permeable materials, particularly soils, wherein the permeameter consists of a water proportioning unit (2), which makes it possible to change different direction (17) of water pumping in the water distribution (5) with a water filter (4), and that either for water pumping from a water source (6) into an application probe (1), or for pumping water from the application probe (1). At the same time, data regarding operation are stored and archived in data logger (15), which forms together with an internal watch (16) a part of the control unit (3). Depending on the type of test, the control unit (3) maintains a set level (11) on a value of level difference (12) relative to stabilized water level (10) in the testing environment by monitoring state of level point (7) immersion. According to the arrangement of the application probe (1) with the level point (7) and the level point (7) grounding (8), connected both through the mediation of an electrical line (9) with the control unit (3), the parameter is suitable for both, measuring water infiltration process at the terrain (13) level by making use of driving rings according to the CZ 2011-245, and newly for measuring permeability of soil in horizons below terrain (13) level, independently on the position of the stabilized water level (10) in the tested environment. Evaporation from the water surface inside the application probe (1) is eliminated by an upper cover (14) of the water level. The first filtration stage of water turbid in the application probe (1) with soil particles is solved by the use of a coarse-grain sinter (18). |
