Abstract: The thermoresistive-based hot-wire anemometer operating at a controlled temperature is a classical architecture that is vastly found in the literature. Nevertheless, this architecture presents a problem due to dynamic range variation with respect to the fluid temperature. In this work an alternative architecture of a controlled temperature anemometer with automatic adjustment of the dynamic range is proposed. Simulations of the proposed system using the parameters from a commercial sensor are presented and compared with the results from a classical configuration.
