Hot Wire Anemometer: Working Principle and Functions
Wed, Jun 29, 2022
The hot wire anemometer is a type of anemometer that converts the flow velocity signal into an electrical signal, and can also measure fluid temperature or density. The length of the hot wire is generally in the range of 0.5 to 2 mm, and the diameter is in the range of 1 to 10 microns. If a very thin metal film instead of a metal wire, which is called a hot-film anemometer. The function is similar to that of a hot wire but is mostly used to measure the flow rate of liquids.
