Permeameter - an overview | ScienceDirect Topics
The disc permeameter is being widely used to characterize the hydraulic properties of the surface of the soil. It is important to describe the multidimensional flow of water away from the circular source.

Properties and Behavior of Soil – Online Lab Manual
Soil permeability (hydraulic conductivity) is the rate at which water flows through soil materials. It is an essential characteristic across a broad spectrum of engineering and earth-science disciplines. The coefficient of permeability (k) is a constant of proportionality relating to the ease with which fluid passes through a porous medium.
Soil water permeameters - Royal Eijkelkamp
The permeameter is a laboratory tool to measure the saturated permeability, or K-factor, of soil samples. It's available in several variations: with an open or closed system, suitable for 5, 10 or 25 samples, and for use with soil sample rings with an external diameter of 53 or 60 mm.
Permeameter - Encyclopedia.com
May 8, 2018 · permeameter A laboratory device for measuring the hydraulic conductivity of rock and soil samples or the coefficient of permeability of soil. Two main types are commonly used: those that require movement of water and those that do not, known respectively as falling head and constant head permeameters.
In order to have flow from any container, the leaving water must be replaced by air. This means that when flow begins in the permeameter, the water in the tube is evacuated first because the tube is the only opening to the atmosphere. Soon, all of the water in the tube is withdrawn and the air-water interface is at the bottom of the tube.
Liquid Permeameter - Vinci Technologies
The robust liquid permeameter allows the determination of a plug- sized core sample’s absolute permeability at ambient temperature and moderate confining pressure. This is achieved by virtue of the steady-state method; specifically, permeability is obtained by inputting the measured pressure gradient and flow rate into Darcy’s law for one ...
