摘要：A thin tantalum foil is sufficiently stable mechanically for supporting a bridge of thin film resistors with a glass insulating layer interposed between them and the foil, while a fluid medium flows past the resistors for measurement of its temperature or for thermal measurement of the rate of flow of the mass of the medium. The resistors form a bridge one half of which is heated to maintain a predetermined temperature for measurement of the rate of flow by means of the heating current, while the other half provides a reference for the regulation of the heating current. A slot in the metal foil between the halves of the bridge provides thermal decoupling between the heated and unheated parts of the bridge.
