Abstract
A fluid speed or direction measuring apparatus utilizes a sensor where an output changes regularly with respect to a temperature change at the resistance-temperature characteristic of a piece of single crystal germanium, thereby converting the temperature change in the single crystal germanium in contact with the fluid into a resistance change, so that the resistance change is converted into voltage, a current or electric power.
