Abstract

The present invention provides a method for detecting the time taken for a fluid to flow through a predetermined section of conduit, which method comprises the steps of: (i) inducing a change in the temperature of the fluid; (ii) detecting the passage of the temperature-changed fluid passed each of a first temperature sensor at a location upstream on the conduit and a second temperature sensor at a location downstream on the conduit; and (iii) determining the time interval between detection of the temperature changed fluid at the first sensor and detection at the second sensor. The invention also provides a heat exchanger apparatus having a holding tube with associated temperature sensors.
