FAQ#019 – Which is the difference between HAE (high-air entry) and LAE (low-air entry) filters?
HAE (High air entry) filters are normally used to monitor pore pressure in the clay core dams and saturated low permeability soils. “High air entry” means high-resistance to air entry when the filter is saturated. The surface tension of the water in the very fine porus of the filter prevents entry of air. The HAE […]
