【Scope of application】

It is used to measure the in-plane water flow of geotextiles and related products under different normal pressures and standard hydraulic gradients.

【Test Principle】

The principle is to change the normal pressure under the prescribed hydraulic gradient and contact material, and measure the in-plane water flow of geotextiles and related products.
