ABSTRACT:
A system and method for determining the operating state of a curable composition utilizes an acoustic wave or signal transmitted into a container holding the composition. In one embodiment, characteristics of a reflected component of the acoustic signal are measured and correlated to pre-determined values indicative of one or more operating states, or degrees of curing, of the composition. In another embodiment, characteristics of a transmitted component of the acoustic signal are measured and correlated. The characteristics include, for example, the speed of sound through the curable composition or the attenuation of the acoustic signal reflected by or transmitted through the composition.
