Abstract
A fluid speed measuring probe utilizing a change in the resistance of a sensor made of a small piece of a single crystal of germanium in accordance with a change in temperature. The peripheral surface of the sensor is covered with an insulating member of a synthetic resin or the like and the outer periphery of the covered sensor is further covered with a spherical metal having heat conductivity. Thus, the directivity of the sensor is eliminated, thereby enabling accurate measurement of the speed of a fluid irrespective of the angle formed between the direction of the flow of the fluid and the probe.
