Parameters of Geotextile Water Permeability Testing Equipment

DW1320N Simplistic vertical water permeability tester is used to determine the water

Permeability coefficient/hydraulic conductivity of geotextiles and related products normal to the plane,without load,by constant head method.A geotextile is subjected to unidirectional flow of water normal to the plane under a range of constant heads.The water flow,needed to keep the hydrostatic head at a constant level,is calculated.Typically a hydrostatic head of 70mm us used plus four additional levels ranging from 20 to 80% of that value.
