A stream of fluid from a system to be monitored is passed through a tube of a fouling probe. One or more heaters surround the tube and heat it so that the resistance to heat flow through the tube wall can be measured. Heat transfer is assisted by a heater mandrel between the heaters and the tube. The space between the inner wall of the mandrel and the outer wall of the tube is filled by an alloy that expands on cooling to provide substancially uniform heat transfer. |
