Hot wire air flow sensor, also known as a hot wire anemometer.
A hot wire air flow sensor measures fluid velocity by sensing the cooling effect of a flow on a heated wire. The wire is heated by an electric current, and as the fluid flows over it, the wire cools down. The rate of cooling is related to the fluid velocity, allowing the anemometer to determine the flow speed.
High Spatial Resolution and Frequency Response: Hot wire anemometers can detect very small changes in flow velocity and respond quickly to these changes, making them ideal for studying turbulent flows and other dynamic airflow phenomena.
Instantaneous Velocity Measurement: Hot wire anemometers can measure the instantaneous velocity of a fluid flow, meaning they can track how the velocity changes over time.
Small Size and Portability: Hot wire anemometers are typically compact and lightweight, making them easy to transport and use in various locations.
Ease of Operation: While the underlying principle can be complex, the operation of a hot wire anemometer is generally straightforward, especially with modern devices.
