About Volume Change Gauge
Volume Change Gauge
When conducting traixial tests on soil samples, it is observed that due to internal pressure, the cell expands, soil specimen consolidates resulting in the change of volume. Volume change gauge is therefore deviced to accurately measure volume changes. This is measured by observing the quantity of water entering or leaving the cell as the cell pressure and axial load are changed it is achieved by the displacement of free surface between the water supplied to the cell and another fluid (paraffin or kerosene). A dye is added to the paraffin for clear demarcation of the interface.
The unit consists of a glass graduated tube of the appropriate capacity graduated to parts of a ml. enclosed in a perspex tube sealed by two end caps. The unit is fitted with manifolds and valves which enable it to be used with the triaxial cell and the constant pressure (Mercury controls) system. The cell pressure can either be directly applied to the cell from the constant pressure system or through the volume change gauge. The graduated glass tube is not subjected to any difference in pressure and its inside is coated with a layer of silicon water repellent to reduce the error in meniscus. There is an arrangement for filling the unit with water and paraffin and a drainage valve is provided in the lower end cap. The whole assembly is mounted on a panel suitable for wall mounting. The unit is supplied complete with a pressure hose with end couplings and a packet of dye.
Salient Features
- Single Burette -10ml capacity graduated in 0.05ml division
- 25ml capacity graduated in0.1ml division
- Twin Burette - 50ml. capacity graduated in 0.2 ml. divisions.
- The unit consists of two glass graduated burettes of 50 ml. x 0.2 ml. capacity enclosed in two perspex tubes sealed by two end caps.
- The manifold with valves enable the flow of fluid in the burettes to be reserved when the paraffin interfaces reach their limits in the burettes, the maximum capacity of measurement being only limited by the capacity of the mercury pots.
- The two burettes, enable the reduction in error in meniscus reading due to reversal of flow, the average of the two burettes being always taken as the volume change reading.
Reliable Volume Measurement for Soil Testing
The Volume Change Gauge is engineered to deliver precise measurement of water displacement during oedometer tests in soil mechanics. Thanks to its transparent burette and robust stainless steel frame, users can visually monitor volume changes up to 100 ml.

Its analog display is intuitive to read, and the device functions efficiently at temperatures ranging from ambient to 50C, making it suitable for a variety of controlled test conditions. Manual operation ensures reliability, free from electrical interferences.
FAQs of Volume Change Gauge:
Q: How does the Volume Change Gauge operate during soil mechanics tests?
A: The gauge operates by manually controlling water flow with a valve, allowing users to precisely monitor the volume of water displaced during oedometer soil testing. Volume change is observed through an analog display on the transparent burette, with readings up to 100 ml.Q: What are the benefits of using this gauge in a laboratory setting?
A: This gauge offers highly efficient and accurate measurements, with corrosion-resistant materials ensuring long-term durability. Its compliance with IS standards and manual control make it ideal for rigorous laboratory use in soil mechanics research.Q: When should the Volume Change Gauge be used in soil mechanics testing?
A: The device is typically used during consolidation testing in an oedometer, where precise measurement of volume change in soil samples is required. It is suitable for tests conducted at room temperature up to 50C.Q: Where can the Volume Change Gauge be installed or positioned?
A: Designed for table-top use, the gauge can be easily set up on any stable laboratory bench. Its compact size and lightweight construction (approx. 2.5 kg) make it portable between workstations.Q: What process should be followed for accurate measurement with this device?
A: Ensure the gauge is properly connected to the oedometer apparatus, calibrate the analog display if needed, and manually operate the valve to control flow. Read the volume directly from the burette for precise results.Q: How can regular maintenance extend the gauges service life?
A: Routine cleaning of the burette, frame, and valves with non-corrosive agents and proper storage after use will maintain accuracy and prevent material degradation.Q: What materials are used to manufacture this Volume Change Gauge?
A: The equipment is constructed from corrosion-resistant stainless steel, transparent glass, and rubber components, contributing to both its longevity and high level of measurement accuracy.
