<p>A constant temperature hot-conductor anemometer includes a set of electrically conductive pins including a pair of inner pins and a pair of outer pins. A conductor is electrically and mechanically coupled to the pins. A current source is coupled to the inner pins. The current source is configured to provide a current through the conductor between the inner pins. A voltage sensor is coupled to the outer pins and configured to measure a voltage across the conductor between the outer pins. The current source and voltage sensor are configured to maintain a constant resistance of the conductor between the inner pins. In an example, a second set of pins, a second conductor and a second circuit are also used to measure dynamic temperature of a fluid and also to calibrate resistances at a known ambient temperature.</p>
