KSAT for determination of saturated hydraulic conductivity on 250 cm³ soilsamples by constant-head and falling-head experiments.

The UMS Ksat System is designed for determination of saturated hydraulic conductivity on 250 cm³ soil samples by constant-head and falling-head experiments. The methodology follows the standards DIN 19683-9 and DIN 18130-1 and is based on the inversion of the Darcy law. The proportionality factor of the amount of water flow through a defined area and the hydraulic gradient is stated as saturated hydraulic conductivity (Ks). This gives our new product the name Ksat.

Advantages

• Measuring the saturated conductivity, Ks, according to DIN ISO 19683-9 and DIN ISO 18130-1 (constant-head mode and falling-head mode)
• Highly precise system, usable for conductivities from 10000 cm/d (takes seconds) down to 0.1 cm/d (takes a day)
• Fully automated measurement
• Real-time visualization, evaluation and storage of the data
• Convenient and robust software KSAT VIEW1.0© with GUI for data visualization and immediate calculation of saturated conductivity
• Integrated recalculation of Ks to desired reference temperature according to the temperature-dependence of the viscosity of water
• Repeated measurements for the same soil sample for long-time monitoring studies are easily done
• No evaporation losses, even with long-time measurements
