1. A fluid analysis assembly for analyzing a fluid, the fluid analysis assembly comprising:
- a chamber defining an evaluation cavity for receiving the fluid;
a fluid movement device having a force medium applying force to the fluid to cause the fluid to move within the cavity;
a pressurization assembly changing the pressure of the fluid in a continuous manner,wherein the assembly is adapted to change the pressure independently of the fluid movement device; and
at least one sensor communicating with the fluid for sensing at least one parameter of the fluid while the pressure of the fluid is changing in the continuous manner,wherein the chamber is characterized as a flow line.

Abstract
A fluid analysis assembly for analyzing a fluid the fluid analysis assembly includes a chamber, a fluid movement device, a pressurization assembly and at least one sensor. The chamber defines an evaluation cavity for receiving the fluid. The fluid movement device has a force medium applying force to the fluid to cause the fluid to move within the cavity. The pressurization assembly changes the pressure of the fluid in a continuous manner. The at least one sensor communicates with the fluid for sensing at least one parameter of the fluid while the pressure of the fluid is changing in the continuous manner.
