The electromotive force of a thermocouple, contained by the probe, indicates a voltage inversely related to the rate of heat dissipation from the probe to the surrounding fluid. With the temperature of the fluid being known or compensated for the rate of heat dissipation from the probe indicates the fluid flow rate.Field of SearchThermal type | |
