Vortex flowmeter providing extended flow rate measurement

A vortex flowmeter for measuring a flow rate of a fluid, the vortex flowmeter comprising:

• a flowtube;
• a bluff body positioned in the flowtube;
• a plurality of sensors, each sensor being configured to generate a signal representing one or more characteristics of the fluid as it flows through the flowtube past the bluff body, wherein at least one of the sensors is located on a portion of the bluff body, and wherein at least another one of the sensors is located downstream of the portion of the bluff body on which the at least one of the sensors is located;
• and
• a measurement processor configured to generate a first flow rate output representing the flow rate of the fluid based on at least one of the signals from the plurality of sensors when the fluid has a Reynolds number of less than approximately 2300 and a second flow rate output representing the flow rate of the fluid based on at least one other of the signals from the plurality of sensors when the fluid has a Reynolds number of greater than approximately 2300;
• wherein the measurement processor is further configured to compare the first and second flow rate outputs.
