PTV ANALYSIS OF COMPRESSED FLUIDS Russian patent published in 2013 - IPC G01N35/00 

FIELD: medicine.

SUBSTANCE: pressure-volume-temperature (PTV) test system comprises a portable medium control chamber 14, a first pressure capsule 12A built into the portable medium control chamber and a second pressure capsule 12B built into the portable medium control chamber with the second pressure capsule being connected with the second pressure capsule. The system also comprises a viscosity metre 18 configured for measuring the viscosity of a fluid flowing between the first pressure capsule and the second pressure capsule, and an optical system 22. The optical system is configured to measure the optical properties of the fluid flowing between the first pressure capsule and the second pressure capsule. Besides, the system also comprises an automatic control system able to maintain an electronic connection with the viscosity metre, optical system and pumps connected with the first and second pressure capsules.

EFFECT: creating the mobile pressure-volume-temperature test system enabling the analysis in place of sampling.
