ABSTRACT:
A method for use in the on-line monitoring of a geometrical parameter of a continuously advancing elongated article and, more particularly, the measuring and controlling of a geometrical dimension of such articles. The method utilizes fluidics to selectively perform such operating functions as signal responsive measuring, comparing, averaging, sensing and controlling, with the apparatus requiring a minimum of circuit interfaces and moving elements. One preferred application of the method is in measuring and controlling the coating thickness of a plurality of pulp insulated wires during manufacture.
