ABSTRACT:
Apparatus for measuring changes in a physical property of a flowing fluid, including a cell through which the fluid flows, the cell having an inlet and an outlet, an inlet tube connected to the inlet of the cell, for delivering the flowing fluid to the cell, and an outlet tube connected to the outlet of the cell, for transporting the flowing fluid away from the cell, the inlet and outlet tubes being mounted in heat-exchanging relationship with each other, so as to transfer heat between the incoming and outgoing fluid and thereby reduce any temperature difference between the incoming fluid and the cell.
