Abstract
A method and apparatus are disclosed which relate to measuring the quantity and thermal insulating value of fibrous material as it is delivered from a source to another location. A feeder mechanism is provided for delivering the material such as insulation to housing from which it is dispensed ultimately to some cavity such as wall space or surface. The housing includes rotary vanes which divide the housing into a number of separate chambers. A measuring system provided with electronic circuitry and acoustical apparatus delivers a controlled acoustical signal to the chamber containing the fibrous material. A sensor senses acoustical signal generated by a source but altered by the fibrous material within the chamber. Signals corresponding to the source signal and the sensed signal are both fed to a comparator which in turn emits a signal proportional to the volume and density, or thermal insulating value of material contained in the chamber.
