Abstract
An enclosure 1 has a measurably variable volume chamber 2, a control for controlling the temperature of the fluid contained therein and apparatus for measuring the pressure of the fluid. The chamber is selectively connectable, on the one hand, to a filling device 6, for introducing the sample, and on the other hand to a fluid extraction apparatus 7, 8. The enclosure 1 is selectively connectable to a tubular loop 9 having a circulation pump 10 and apparatus 11 for measuring the density of the sample of circulating fluid. By varying the volume of chamber 2, the thermodynamic characteristics of monophase and diphase fluids can be accurately determined. The apparatus is especially useful for the study of fluid of hydrocarbon deposits.
