An Assembled Hot Wire Anemometer Design

open access: yesJournal of Measurements in Engineering, 2023
The hot wire anemometer is a commonly used device for measuring air speed in laboratories. In this paper, the relationship between air speed and the hot wire temperature in different air speed ranges was analyzed based on the theory of thermal equilibrium.

Optimization of Single-Sensor Two-State Hot-Wire Anemometer Transmission Bandwidth

open access: yesSensors, 2008
Hot-wire anemometric measurements of non-isothermal flows require the use of thermal compensation or correction circuitry. One possible solution is a two-state hot-wire anemometer that uses the cyclically changing heating level of a single sensor.
