Abstract: A fluid flow meter is of the type including a heated probe sensor of known electric resistance dipped into or swept by a fluid stream having a predetermined velocity. The sensor is capable of converting each flow velocity value to a voltage value, and is connected to a processor operating using fuzzy logic for producing the flow measurements. The sensor may be an NTC thermistor. The thermistor may be powered from a current generator, and the processor may include a neural network. The sensor may include at least two discrete thermistors, one being a hot thermistor and the other being a cold thermistor.
