The Archimedes bulk volume measurement system is designed to rapidly and accurately
determine the Bulk Volume (VBAbulk) of a saturated
or partially saturated sample gravimetrically. The Vbulk is determined by weighing
a sample suspended in air followed by a weighing submerged under liquid the weight
difference is then divided by the liquid density to give the bulk volume of the
sample. Measurement time is approximately 20 seconds per sample with an accuracy
of ± .001 cc. Sample placement into and removal from the liquid, data acquisition,
data reduction and storage functions are performed the operating software running
on a Windows based PC.
The system is comprised of a digital balance, Plexiglas balance stand which houses
the submerged weighing work station, articulated sample basket and a stainless steel
liquid basin for solvent or brine. Availably, as shown with optional PC based data
acquisition system which can also integrate a digital caliper workstation.
