Adjustable flow nozzle for air flow meter

摘要

The aspects of the present invention provides 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 an adjustable member having a substantially planar surface. The nozzle is configured for operative connection to an air flow meter. 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 adjustable member is operatively connected to the nozzle. The member adjusts axially to control the depth of insertion into the foam.
