DW1380

DW1380 In-plane Water Flow Rate Tester for Geosynthetics is applied to determine the in-plane water flow rate of geotextile or geotextile-related product under varying normal compressive stresses and standard hydraulic gradient using a constant head.

Features

· The machine is made of acrylic and aluminum profile, beautiful and not easy to rust;

· Compact structure, easy to install;

· Reasonable waterway design, simple to operate;

· With water storage tank, good environmental adaptability;

· It's safe and reliable to apply constant normal pressure to the specimen by pneumatic loading;

· High precision pressure gauge is easy and reliable to read;

· Continuously adjustable wide range of head loss can be realized by water level control system with two overflow ports;

· The height value of water head is read from the water level scale with a reading accuracy of 1mm;

· Equipped with closed-cell rubber of various thicknesses, adapt to specimens of different thickness.
