Description

The BPS350 permeameter is a manually operated system that neatly performs liquid permeability determination experiment tests at pore pressures and confining pressures up to 5,000 psi. The standard system includes a low pulsation High Performance Liquid Chromatography (HPLC) pump for fluid delivery at flow rates ranging from 0.01 ml/min to 10 ml/min, and a manually operated hydraulic pump to generate and maintain confining pressure. Two fluid accumulators are used for fluid storage. Core plugs are placed in a horizontally-mounted Hassler core holder. Sample dimensions can be customized upon request. Pressure gradient is measured by a highly accurate differential transducer of 0-500 psid range. A manual bypass valve protects this sensor from dangerous overpressures. To prevent external effects, isobaric outlet pressure conditions are ensured via a dome-loaded backpressure regulator. An optional gas line allows relative gas permeability determination. Gas is injected through the core and the measured flow rate is utilized to calculate the end point relative permeabilities Krg (permeability relative to gas).
