Abstract
A rheometer and a method for measuring rheological properties of a fluid material, especially in an in-line arrangement in a manufacturing process, include capturing and confining a volume of the fluid material against movement within a chamber, advancing an orifice plate having an orifice into the confined volume of the fluid material in the chamber such that the fluid material flows relative to the orifice to pass through the orifice plate, and determining the pressure in the confined volume of fluid material as the orifice plate is advanced into the chamber and through the confined volume of fluid material and the fluid material passes through the orifice, the pressure being indicative of the rheological properties being measured.
