HUMBOLDT HM-5893 Falling Head Permeameter Cell, 4.5 Inch

Humboldt HM-5893 falling head permeameter cell is used in soil permeability testing, where the rate of water flows through soil is measured. This device finds application in various engineering projects, including the construction of dams, roads and buildings, as well as in environmental studies to assess groundwater movement and contamination risks.

Working Mechanism:

• Humboldt HM-5893 falling head permeameter cell operates by introducing water into a soil sample and measuring its downward flow under gravity. As the water permeates through the soil, the decrease in water level inside the cell is monitored over time. This data allows engineers to calculate the coefficient of permeability of the soil sample.

Features:

• It features a spring mechanism in the top cap, ensuring consistent force application.
• This falling head permeameter cell has anodised aluminium end caps and a clamping ring for durability.
• It comes with valves and perforated screens for precise control and accurate measurements.
• This falling head permeameter cell offers portability and compactness for on-site testing convenience.
• It is equipped with a design optimised for granular soil analysis.
• The cell incorporates a falling-head method for laminar flow assessment.
• It features a user-friendly setup, facilitating efficient operation and reliable results.

Compatible Accessories:

• Humboldt HM-5803.8.0 Permeameter Replacement Screen: It is designed for use with falling head permeameter cell for functionality and reliable soil permeability testing.

Frequently Asked Questions:

Q. Why is soil permeability testing important?

A. Soil permeability testing helps engineers understand how water moves through the soil, which is crucial for designing effective drainage systems, assessing foundation stability and managing environmental risks such as groundwater contamination.

Q. What is the difference between falling head and constant head permeameter cells?

A. Falling head permeameter cells measure soil permeability using a decreasing water head, while constant head permeameter cells maintain a constant water head. The choice between them depends on the specific soil characteristics and testing requirements.
