- 1 - Abstract: For use in a hot wire air flow meter, a platinum wire is coiled and coated with a glass material. Its ends are welded to support members to form an exothermic resistor with no bobbin therein. One such bobbin-free resistor is used as a hot wire element and another is used as a cold wire element in the meter. The heat generated in the coiled wire is almost entirely carried away through the air. In this way the transient response characteristics upon a sudden change of the amount of air flow can be improved.
