DOUBLE-RING INFILTROMETER

This device is specifically designed to measure the rate at which water penetrates the ground, providing essential data for determining soil permeability. Permeability is a crucial property in soil science, reflecting the soil's ability to allow water to pass through it. This is quantified by measuring the amount of water that passes through a unit area of soil in a given unit of time. The permeability ratio is calculated using these measurements, often with the application of Darcy's law, a fundamental principle in fluid dynamics that relates the flow rate through a porous medium to the properties of the medium and the fluid.

The complete apparatus includes two rings of different diameters—30 cm and 45 cm—designed to accommodate various testing conditions and soil types. The use of rings of different sizes helps in creating a controlled environment for the test, ensuring accurate measurements of the water infiltration rate. The device also includes an actuation plate, which is used to apply a consistent force, driving the rings into the soil with the help of a hammer. This ensures that the rings are properly seated in the ground, minimizing any potential for errors due to soil disturbance or uneven application.

A water level indicator is also part of the setup, allowing for precise monitoring of the water level during the test. This is crucial for determining the rate at which water infiltrates the soil, as consistent water levels are necessary for accurate and repeatable measurements.

For more advanced and automated testing, a data logger-based automatic osmometer is available as an option. This feature enables continuous monitoring and recording of water infiltration over time, reducing the need for manual observation and allowing for more precise and detailed data collection. The data logger automatically records the changes in water level, providing a comprehensive dataset that can be analyzed to determine the soil's permeability with high accuracy.

Overall, this device is an essential tool for geotechnical engineers, soil scientists, and environmental researchers, providing reliable and accurate measurements of soil permeability that are critical for a wide range of applications, from agricultural planning to construction and land management.
