A method of monitoring the application of an insulation, which includes a layer of cellular insulation, to an elongated conductive material, was comprised of advancing an elongated material, measuring the capacitance and the associated diameter of the insulated elongated material, and utilizing the signals to control the weight of insulation per length of elongated material and the percent of voids in the cellular insulation material to maintain the capacitance and associated diameter within specified ranges.
