It is suitable for measuring the water permeability of planar drainage materials in Railway Engineering geosynthetics. Under laminar flow condition, a certain normal load is applied on the surface of the sample, and a certain head difference is applied at both ends of the sample to measure the water flow through both ends of the sample in a certain period of time.
