Abstract
A fluid velocity sensor can include a thermally conductive body comprising a first temperature sensor, a second temperature sensor, and a third temperature sensor. A heating element is secured within the fluid velocity sensor to heat the thermally conductive body. The first temperature sensor, the second temperature sensor, and the third temperature sensor each reside within the thermally conductive body at different radial distances from the heating element. A flowrate of a fluid in contact with the fluid velocity sensor is determined based on a comparison between the internal temperatures measured by each of the first, second, and third temperature sensors.
