Abstract

A device for measuring the cross-sectional area of an article without direct contact therewith, of high precision and sensitivity, which can operate in a wide range of environments, comprising; a measuring coil to which an oscillator is functionally connected with means for measuring the variation of the inductance of the coil as the article passes through it, the measurements being expressed as cross-sectional area.
