ABSTRACT:
A hot-wire sensor integrally measuring material or volume flows in a conduit must be so configured that an integral average velocity can be determined. This takes into account the variable velocity distribution along the radius. To achieve the foregoing, the hot wire either is installed opposite the longitudinal axis of the conduit or has a thickness which changes symmetrically with respect to the longitudinal axis of the conduit with the portions of larger thickness being disposed near the inner wall surface of the conduit.
