DEVICE FOR DERTERMINING ON AN ACTIVE SITE SAMPLE CHARACTERISTICS OF FOR EXAMPLE PETROLEUM FLUIDS

摘要

in a thermostatic chamber (7) is fixed a rigid body comprising two cylindrical chambers (14, 15) with a bottom cutting edgefor example, related to one another by a channel end controlled by a valve v5. two rods (18,17) of piston with sealsprestressed sealing (j) can slide in the two chambers, separately or coupled to one another. the form is adapted tothe bottom of the chamber. the displacement of the displacement rod is vertically provided with means (12,13)threaded rods (7) rotated on command (me1, me2 by motors. a control system comprising two blocks ofoptical visualization and retrieval (19, 20) through the body at the level of the bottom of the lower chamber (14) of the sensors.pressure, temperature, displacement, under the control of a microcomputer, generates thermodynamic measurementsaccurate sample substance under high temperature and pressure. the gas is preferably provided in the chamber(7). according to another implementation method, the upper chamber can be replaced by a gasometer for validationfor the samples.
