Abstract: A compensated flowmeter having a probe adapted to project into flowing media within a conduit. The probe includes a thermal dispersion sensor, and a compensating gas properties sensor contained within a no-flow chamber of the probe. The thermal flow sensor has active and reference sensor elements that responsively provide output signals relating to a flow rate of the media.
