Abstract
The aspects of the present invention provide for an apparatus for conveying air into foam so that the flow of air within the foam may be monitored to determine one or more characteristics of the foam. The apparatus includes a nozzle and a member having a substantially planar surface. The nozzle includes a tube sized and dimensioned to be inserted easily into the foam. The tube has a wall and an aperture formed in the wall. The aperture is sized and dimensioned to allow air to flow through the aperture and into the foam, and the aperture extends partially about the circumference of the tube. The member is mounted to the nozzle and is also connected to an air flow meter.
