Abstract
Apparatus and a method are described for measuring heating and/or cooling of air or other fluid that occurs between an inlet and an outlet, one being a low-temperature passage and the other being a high-temperature passage. Heat is supplied to a temperature sensor in the low-temperature passages sufficient to raise that sensor to the temperature sensed in the high-temperature passage where the sensor of the low-temperature passage is cooled both by the fluid temperature and its mass-flow rate, and the supplied heat is measured.
