<p>Fluid flow properties often dictate the performance of processing operations. The present invention relates to a system for evaluating properties of a fluid flowing in a pipe. A test cell ( 20 ) which includes two parallel surfaces ( 5, 6 ) which are positioned in the flow. One of the surfaces is moveable relative to the other, to a position in close proximity to the other, to create a stagnant flow region between the surfaces. The system further includes a test input device ( 10 ) to apply input motion to one of the surfaces, and a test output device ( 13 ) to measure output motions from the cell in response to input motions. Furthermore, the system includes a processing device ( 9 ) to calculate rheological parameters of the fluid from signals produced from the test input and test output device. There is also a process for evaluating properties of a flowing fluid.</p> |
