Abstract
The present invention relates to an apparatus and method of measuring effective porosity of various media such as rock or soil using radon that is an inert gas. An apparatus of measuring porosity according to the present invention includes: a gas component detector having two ports and configured to measure a concentration of a predetermined gas; a gas vessel having two ports and configured to accommodate the predetermined gas; a medium vessel having two ports and configured to accommodate a medium, of which the porosity is desirous to be measured; pipe lines connecting the ports of the gas component detector, the gas vessel and the medium vessel; and valves installed on the pipe lines.
Claims17
An apparatus flail for measuring porosity, comprising:
- a gas component detector having two ports and configured to measure a concentration of a predetermined gas;
- a gas vessel having two ports and configured to accommodate the predetermined gas;
- a medium vessel having two ports and configured to accommodate a medium, of which the porosity is desirous to be measured;
- pipe lines connecting the ports of the gas component detector, the gas vessel and the medium vessel;
- and
- valves installed on the pipe lines,
- wherein the pipe lines and the valves are arranged and installed to form a first loop wherein the gas component detector is not connected to both the gas vessel and the medium vessel, a second loop wherein the gas component detector is connected to the gas vessel and not connected to the medium vessel, and a third loop wherein the gas component detector is connected to the medium vessel and not connected to the gas vessel, and the valves switches between the loops.
