ABSTRACT:
A method of and apparatus for measuring a fluid flow speed using a current controlled heat sensor. A first signal is extracted from the heat sensor for a first value of current. The value of the current flowing through the heat sensor is modified and, from the same thermal sensor, a second signal is extracted for a second value of current. These signals are then processed by a fuzzy logic microprocessor to obtain a value of the speed of flow of the fluid.
