GBV-Geometric bulk volume meter


The tool is designed to measure bulk volume of plug sized and/or full diameter cores with excellent accuracy. Multiple axial and radial measurements of a specimen are taken by means of a digital caliper. The latter can optionally be connected to a PC and automatically export the data to a specific statistical analysis software capable of computing Geometric bulk volume, effective flow area, caliper bulk factor and shape factor. A minimum of 4 measurements along the diameter and one every 50 mm along the length are recommended to produce a statistically significant result.
