ABSTRACT:
A method and apparatus constructed to measure the fluid present in a multifilament or fiber strand moving at high speed is described and involves conductive contact points along the strand path which contact the strand and generate signals. The signals which are conductance measurements are synchronously demodulated to produce a signal representing the volume of fluid in the strand.
