Flow velocities can be determined by correlating the temperature noise conveyed by the fluid flows as found in process or chemical industries. Temperature fluctuations as low as 0.1 K provide useful signals. The system developed to measure flow velocities in thermohydraulic experiments comprises a sensor, one amplifier and a computer controlled signal handling system. Three examples of applications are presented: a) in the main coolant pipe of the LOBI facility; b) in the annular downcomer gap of a steam generator; c) in a Mettler calorimeter.
