Abstract:
1. A method of measuring flow of air in a foam, the method comprising the steps of: identifying a depth of insertion in the foam; adjusting a flange member to the identified depth of insertion, wherein the flange member has a substantially planar surface adapted to form a substantially air tight seal when abutting an external surface of the foam, and wherein the flange member is directly connected to a nozzle; inserting the nozzle into a point of insertion in the foam, wherein the nozzle comprises: using the planar surface of the flange member to form a substantially air tight seal with the external surface of the foam, proximate to the point of insertion of the nozzle; receiving air from an air source; and disbursing the air through the aperture, thereby causing the air to flow around fused beads of the foam; using an air flow meter to measure the air flow around the fused beads in the foam to obtain a measurement of air flow, wherein the air flow meter is directly connected to the nozzle to allow unimpeded flow between the air flow meter and the nozzle; and determining the density of the fused beads based on the measurement of air flow.
