Abstract
An apparatus and method to measure different properties of a liquid film or coating traveling or resting on a horizontal support, including dynamic viscosity, dynamic surface tension and surface dilational elasticity, the apparatus comprising: a series of wires placed above a moving wet film or coating to which high voltage is applied inducing an electrostatic field that lifts the free surface of said film preferentially near the wires; a means for detecting the free surface displacement of the free surface in the section where the voltage is applied to the coating, possibly the means being a CCD camera coupled to a digital acquisition system; and means for processing the signal to determine the properties of the coating.
