Abstract:

Some pneumatic devices are discussed in which thermal-jet anemometers are used to convert negligible fluid flows into electric signals. Several types of differential thermal anemometers are considered by means of which it is possible to determine not only the rate of fluid flow but also its direction. Emphasis is placed on configurations with inner and outer fluid flow past heat-sensitive elements, and on single-chamber and double-chamber jet elements. It is noted that the sensitivity of semiconductor thermal-jet anomemeters is considerably higher than that of other devices. General design problems are considered for two instrument types with thermal-jet anemometers. Author
