American Mineralogist (1982) 67 (3-4): 269–276.
...Janet A. Schramke; Derrill M. Kerrick; James G. Blencoe Abstract A new experimental method has been developed for the investigation of kinetically-rapid devolatilization reactions at pressures up to approximately 8 kbar. Using a volumometer system within an internally-heated pressure vessel...

..., confining pressure and pore pressure were held constant, while axial stress was allowed to relax. The shear and normal stresses on the experimental fault were calculated using the effective axial and confining loads. The resulting pore volume loss was monitored with a volumometer with resolution of 0.0047...

... volumometer was used to measure the expulsion of pore fluid during the compaction process. Although this device worked well for experiments of short duration and/or at low pore pressures, in many tests it was plagued by small-volume leaks over long periods. The quartz sand used was a washed natural...

... pore fluid pressure and serves as a high precision volumometer. This system can be used to measure permeability through various methods including the pulse transient technique ( Brace et al. 1968 ) applied in this study to obtain values of permeability for the fault gouges at different confining...

... for independent control of effective pressure ( P E = P c − P p ). Both P c and P p were monitored by transducers with resolution better than 0.01 MPa (of order 1 psi). A volumometer monitoring the change in pore-fluid volume provides a measure of sample volumetric strain with resolution better than...

..., and the upstream pore pressure was controlled using a volumometer driven by a servo-controlled motor ( Fig. 6 ). To achieve the highest data resolution possible, the volumes of both upstream and downstream reservoirs were kept to a minimum, and the plumbing was insulated to minimize temperature fluctuations...
