Low cost anemometers for wind tunnel and ventilation applications

Abstract:

Low cost and simple constant current and pulsed constant temperature anemometers are described. The proposed anemometers use a self-heated thermistor as a flow sensor and very simple electronics are used. Data acquisition and control use commonly available micro-controllers. A simple heat transfer model is used to simulate the main characteristics of the sensor and laboratory tests show that the calibration curves of the sensors are repeatable and even though the sensor has a spherical shape, a directional sensitivity is noticeable.
