Hydraulic permeability testers are used to measure the permeability of granular solid materials. They involve flowing a fluid through a soil sample in a controlled manner. The rate of flow is measured, allowing the soil permeability to be quantified.

Hydraulic permeability testers are used to investigate the properties of soil samples, such as grain size, void ratio and permeability. They are an important tool for geotechnical engineers and can be used in laboratory or field environments. They are also used in areas such as irrigation, earthquake engineering and landfill design.

Hydraulic permeability testers work by flowing a fluid through a soil sample, typically water or air. The rate of flow is measured, allowing the permeability of the sample to be calculated. The testers usually have a loading frame to control the pressure of the soil sample, as well as a pressure gauge to measure the flow rate.

Hydraulic permeability testers come in a variety of different designs and sizes, depending on the application. The most common type is a hand-operated device, which can be used for small samples. For larger samples, an automated system may be required. Many of these automated systems can be used for in-situ tests, allowing the permeability of a soil to be measured without having to remove it from its original location.

Hydraulic permeability tests are an important tool for geotechnical engineers. They can provide valuable information about the properties of a soil sample and can help engineers design structures to best suit the soil conditions.
