摘要:
A flow measurement probe (300) includes an elongate probe having an averaging pitot tube (302) with a plurality of upstream and downstream openings (303) arranged along a length of the elongate probe, and a thermal flow measurement sensor (304) coupled to the elongate probe. A method of measuring fluid flow rate in a process includes calculating a flow rate of the fluid using differential pressure in upstream and downstream openings (303) of an averaging pitot tube (302) in an elongate probe when the differential pressure is at least a defined measurement threshold, and calculating the flow rate of the fluid with a thermal mass flow sensor (304) coupled to the flow measurement probe (300) when the differential pressure is less than the defined measurement threshold.
