ABSTRACT:
A flow meter capable of performing within gas flows exhibiting temperatures above about 600.degree. F. includes a thermally-stable housing formed of fire brick or the like through which a passageway is formed. A resistance temperature sensor (RTD), serving as a reference is positioned at the entrance region of the passageway, while a heater coil and RTD temperature sensor are located toward the exit opening of the passage. The latter components are located within a heat confining region of the passageway which is so configured with respect to its length and diametric extent as to define a heat confining chamber which substantially reduces radiant heat loss, conductive heat loss, and convective heat loss not occasioned by gas flow to achieve heretofore unavailable performance.
