ABSTRACT:
There is provided an apparatus for the measurement of the velocity of gases, especially for the intake of internal combustion engines, consisting essentially of an electronic unit and a hot-wire anemometer, with two or more temperature dependent resistances with the highest possible temperature coefficients which together with two temperature independent resistances are connected to form a bridge. The temperature dependent resistances are made of a thin metal coating which are placed on electrically insulating carriers.
