New type of hot-wire/film anemometer

A new type of intelligent hot-wire/film anemometer was developed by analyzing the shortcomings of traditional hot-wire/film anemometer. The author established a more precise dynamic equation of constant-temperature hot-wire/film anemometer with main bridge prephasing circuit and gave its analytic solution and a set of formulae for design. Three adjustment parameters are reduced, thus the adjusting procedure is greatly simplified. The new type of anemometer can work more stably for its synchronous bias circuit than the traditional anemometer. And it also has other advantages.
