ABSTRACT:
A device for studying an aging of a fluid circulated in a loop or closed circuit by imposing, for example, predetermined temperature, pressure or shear conditions on the fluid in order to determine rheologic properties of the fluid. The device includes a loading pump, a circulating pump, a filtration governor pump and an injection and draw-off pump, a flow meter, a viscosimeter for discontinuous measurings, a narrowing or reduction for causing a shearing of the fluid, a number of filters interconnected in series, a sampling cell, pressure and temperature pickups, heating jackets and heat insulation sheaths for maintaining a homogenous temperature all along the loop, and a control system which includes a programmable automaton associated with a microcomputer in order to pilot numerous operating sequences. The device is constructed so as to maintain constant conditions imposed on the fluid regardless of the type of measurements being effected.
