Manufacturer: Vinci Technologies
Model Number: Wholeperm
The wholeperm instrument is dedicated to measure horizontal and vertical permeability to gas (air, helium, nitrogen,..) of full size core samples at room conditions. The instrument is provided with a gas perrmeameter console, a full size coreholder and a data acquisition computer station. The air permeability determination is based on the steady state method. The instrument is designed for the injection of gas through the test sample at various conditions of pressure and flow rates. The injection pressure at the core face is measured using a pressure transducer and the gas flow rate is measured using a precision mass flow meter. The permeameter console features a precision pressure metering valve to vary the pressure differential and gas flow in the core which allows for the determination of slip factor and Klinkenberg permeability versus reciprocal mean pressure relationship.
