FIELD: measurement technology. SUBSTANCE: proposed permeameter is specifically related to devices for field measurement of hydraulic conductance, sorptivity and $$$ parameter of porous materials for example, soils. Invention can be used in design of irrigation and drainage systems, canals, dams, ponds, foundations and bases and for ecological and land reclamation purposes. Permeameter transparent in its upper part is manufactured in the form of straight mobile barometric tube coaxial to bearing tube. Upper part of permeameter is connected by flexible shut hoses to sealed reservoir anchored on bearing tube which can be easily separated from it. Sealed reservoir is fabricated in the form of vertical cylinder with constant internal section. EFFECT: increased accuracy of measurement of hydraulic conductance, sorptivity and $$$ parameter, improved operational characteristics. 3 cl, 1 dwg |
