Flow measurement probe with pitot tube and thermal flow measurement

A flow measurement system, comprising:

• a flow measurement probe comprising:
• an elongate probe comprising an averaging pitot tube element having a plurality of upstream and downstream openings arranged along a length of the elongate probe and at least one opening extending between an upstream side of the elongate probe and a downstream side of the elongate probe, the at least one opening between at least two of the plurality of upstream and downstream openings;
• and
• a thermal flow sensor disposed in the at least one opening and within the elongate probe;
• and
• a process variable transmitter coupled to the flow measurement probe, the process variable transmitter comprising:
• a microprocessor to determine a flow rate output based on inputs from each of the thermal flow sensor and a differential pressure sensor coupled to the averaging pitot tube, and by blending the inputs together to form a single signal indicative of a flow rate for a flow range covering each of a flow range of operating measurement of the differential pressure sensor and of the thermal flow sensor;
• memory coupled to the microprocessor to store transmitter configuration data;
• and
• an output communication element to output the flow rate output signal.
