GEAR DETERMINING LIQUID PERMEABILITY THROUGH POROUS MATERIALS Russian patent published in 1997 - IPC

Abstract RU 2092811 C1

FIELD: powder metallurgy, analytical instrumentation. SUBSTANCE: gear has device measuring speed of rotation of electric motor setting in motion pump feeding liquid which is controlled by controller on basis of microprocessor. Sample holder includes pressure transducers measuring liquid pressure inside and outside sample also coupled to controller which is connected to temperature transducer, capacitive pickup composed of capacitance and vitrified electrode. Controller is connected to digital indicator. EFFECT: increased authenticity of determination of liquid permeability. 2 dwg
