Abacus Bulk Volume Weigh Station is an easy-to-use bulk-volume apparatus that uses
the fluid displacement principle (with a reservoir for approximately 300 ml of mercury)
to determine quickly and accurately the Bulk Volume (BV-Hg) of plug-size core samples.
The apparatus includes an electronic balance with an integrated, mercury-immersion
reservoir interfaced with a personal computer.
The host computer system for data acquisition and control, utilizes a Windows based
graphical interface to guide the user through the operation of the ABACUS system.
The operating software allows the operator to acquire and save sample measurement
data in HTML format, compatible with the common spreadsheets, databases and word
The ABACUS graphical user interface accepts sample entry by number or
by depth and allows the operator to measure sequentially or randomly BV-Hg, sample
weight and dimensions. Mercury-immersion bulk volume BV-Hg, weight, data are calculated
and stored to disk or sent to optional printer. The included digital calipers measure
accurately the length and diameter of the plug samples. The measured data is automatically
logged to the computer providing automatic calculation of flow area, caliper bulk
factor and shape factors.
ABACUS requires operator input of ambient room temperature to calculate and apply
automatically the operating density of the mercury.
