<p>A transducer is disclosed for sensing flow of a fluid. The transducer includes means for applying a heat pulse to the fluid and at least one temperature sensor. The temperature sensor is adapted to detect a decaying response to the heat pulse to provide an indication of the flow. The decaying response may be detected by comparing measured voltages at a set moment in time or by comparing measured times at a set voltage threshold. A method for sensing flow of a fluid is also disclosed.</p>
