A LOW COST IMPLEMENTATION OF THE SETTLING-TUBE MEASUREMENT TECHNIQUE FOR SAND GRANULOMETRY

A. Papalazarou, K. Albanakis, Th. Laopoulos
Abstract:
The settling-tube measurement technique is implemented by an experimental setup developed and tested for low-cost automated sand granulometry. The measurement is based on monitoring very small pressure variations created by samples of sand as they settle down in a water-filled cylinder. The pressure variations are monitored by low cost air-pressure differential transducers in an appropriate experimental setup which monitors air pressure variations caused by water pressure variations. It is shown that this low-cost automated approach manages to calculate properly size distribution and other statistical parameters of sand samples efficiently and quickly offering thus an attractive alternative to the traditional sheaving method.
