Hot-wire anemometer for spirography
Medical & Biological Engineering & Computing, 1998The use of a constant temperature hot-wire anemometer flow sensor for spirography is reported. The construction, operating principles and calibration procedure of the apparatus are described, and temperature compensation method is discussed. Frequency response is studied.

Uncertainty-Aware Calibration of a Hot-Wire Anemometer With Gaussian Process Regression
IEEE Sensors Journal, 2019Expensive ultrasonic anemometers are usually required to measure wind speed accurately. The aim of this work is to overcome the loss of accuracy of a low cost hot-wire anemometer caused by the changes of air temperature, by means of a probabilistic ...

A micro silicon hot-wire anemometer
1995 IEEE TENCON. IEEE Region 10 International Conference on Microelectronics and VLSI. 'Asia-Pacific Microelectronics 2000'. Proceedings, 2002A new micromachined hot-wire anemometer has been developed. Extensive tests of the anemometer's dependence on ambient temperature, over-heat ratio, and sensor length have been finalized. Due to its extremely small size, micromachined hot-wire has better sensitivity, temporal and spatial resolutions than the conventional hot-wire.

A constant temperature hot-wire anemometer
Journal of Scientific Instruments, 1967A compact, inexpensive, constant temperature hot-wire anemometer circuit using solid state operational amplifiers is described. A theoretical expression for frequency response and an experimental check are given. Theoretical and experimental response data for an existing unit are shown.

Calibration Unit for Hot-Wire Anemometers
Measurement Techniques, 2004The proposed calibrating unit for hot-wire anemometers can reproduce the unit of airflow velocity to within ±0.65% in the range 0.026–4.65 m/sec. Ways of improving the metrological characteristics are considered.

Practical hot-wire anemometer excitation modes
SPIE Proceedings, 2004The operation of a thin film hot wire directional anemometer is demonstrated using three modes of operation; constant voltage, constant current, constant resistance, and the heating response and characteristics for the different excitation modes observed. Evaluation is primarily by experimental approach.

A directionally sensitive hot- wire anemometer
Experiments in Fluids, 1997A new directionally sensitive velocity measurement system based upon a single oscillating hot-wire probe has been developed. The vibration of the hot-wire was effected by a piezoelectric oscillator that could be driven at different amplitudes and frequencies.
