ABSTRACT:
A flow metering apparatus comprising an elongated vortex generating element disposed transversely in a stream of fluid to produce on opposite sides thereof vortices which are shed in alternating fashion and a sensor disposed downstream of the generating element and aligned therewith in such a manner that the vortices alternately pass along opposite sides of the sensor. The sensor comprises an elongated, cylindrically shaped support having two high TCR resistive films longitudinally disposed on the surface thereof which faces the vortex generating element. This combination of vortex shedder and sensor produces a strong, highly reliable electrical signal.
