    • Questions?

    Single Tube Manometer is used for measuring soil permeability with the following Karol-Warner Permeameter models: Shelby Tube, Compaction, and Constant / Falling Head Permeability Test Sets. The Single Tube Manometer connects to a Permeameter port and is used in measuring the permeability of soils in falling head tests. The 1,000mm acrylic tube Manometer has one valve to control flow and a built-in scale with 1mm graduations to monitor. Each Manometer includes a floor stand for easy use on flat surfaces.

    Model 3859 has an adjustable funnel and clamp to act as a reservoir for constant head tests.

    Features:

    • 1,000mm capacity
    • Scale has 1mm graduations to monitor flow volumes
    • Floor stand allows for flexibility of use throughout testing area
    Included Items:
    • Single Tube Manometer or
      Single Tube Manometer with Constant Head Reservoir
    Estimated Shipping Weight 40.0lb (18.14kg)

    Common Questions


    What is a Manometer and what is it used for?

    A Manometer is a pressure measurement device that can be used with a Permeameter to determine soil permeability.

    What does a Manometer measure?

    The difference in pressure between two points, or one point and the atmosphere.

    What is pore pressure in soils?

    The pressure of groundwater within the gaps, or pores, of soil or rock samples.

    What is the meaning of negative pore pressure?

    When soil voids are filled with air, the pressure reading is zero. When the voids are filled with water, there is negative pressure resulting in increased shear strength.

    What is the fluid in a Manometer?

    For the Single Tube Manometer, water is used to measure pressure differences. Some Manometers use mercury or other heavy liquids to measure higher pressure differences. When using mercury-based devices, always review local regulatory restrictions.
