Abstract
A flow measurement probe includes an elongate probe having an averaging pitot tube with a plurality of upstream and downstream openings arranged along a length of the elongate probe, and a thermal flow measurement sensor 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 of an averaging pitot tube 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 coupled to the flow measurement probe when the differential pressure is less than the defined measurement threshold.
