Hot-Wire Anemometers

GAO Tek hot-wire anemometers operate on the principle of convective heat transfer. They consist of a fine wire, usually made of platinum, which is electrically heated. As the fluid (air or gas) flows over the wire, it cools the wire, and the instrument measures the electrical resistance changes of the wire to calculate the flow velocity. The higher the flow velocity, the greater the cooling effect, resulting in a corresponding change in resistance. Benefits of Hot-Wire Anemometers: hot-wire anemometers offer high sensitivity, a wide range of measurements, fast response time, low mass flow disturbance, the ability to measure turbulent flows, compact design, and applicability in various environments.
